1993 Buick Park Avenue Won't start

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it

my care will not start, when I turn the key, I hear a sound that sounds like a muffled popping noise, but the car never turns over. I had experienced the problem before and took it to a mechanic and he told he unhooked the crankshaft sensor and then plugged int back in and it did start after that which was about 2 months ago until now. The mechanic stated that he did not see anything else wrong and if the cranskshaft sensor was bad it woudl have not cranked at all. Do you think the crankshaft sensor is going bad or is it something else.

thanks for the info. the engine will turn over but will not start. the last time it happened i had a mechanic remover the crankshaft sensor and put it back in and it started with no problem until yesterday. he stated that if the crankshaft sensor was bad it would have not started at all, but i will get the other issues looked into as well.

thanks,

one day i left the doctor's office & it took me about two hours to get it started. Once it started i was able to drive it home. the next day i tried to leave my house it would turn over but wouldn't start. the fuel pump seems to be working, it seems to be getting fuel but maybe not enough? any suggestions?

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

We have a new battery, redone tranny, car will start then immediately die. If a door is ajar or if we have locked the car sometimes it won't start either. We have to reset it by locking them again then the horn/security system will honk after 20 minutes and then SOMETIMES you can start the car. We have been leaving it unlocked, all doors closed tightly and the car hasnt' started for 2 days.
Security system issue? Key issue? Crank Shaft Positioning sensor maybe?

First of all thank you so much for your donation.When the car doesn't start is the security light on or flashing?Also does the car turn over when it doesn't start?If it does turn over when it doesn't then i need you to check for spark and what the fuel pressure is.Also what is the 8th digit of the vin?

Thank you for your response. The engine starts and immediately dies, lasting 2-3 seconds tops. The security light had been on solidly and my husband reset the security sensor (just since I posted on the board), hoping to be able to start it and at least get it home for the weekend - but it did not work. The 8th number of the VIN is K


Thanks so much,
Adrienne

I emailed you some trouble tree's one for crank's but won't start and one for security light stays on solid or flashes plus a wire diagram.I would print them all out so there easier to read and portable.You will also need a multimeter to do the testing.Let me know what you find.

Thanks Louie,

I received those pages, thank you so much for sending them. I did print them out and will take them home with me this evening. I am encouraged and hopefully this won't be another $700-$1000 fix.

What did the digit in the VIN tell you (out of curiosity)?

Thanks,
Adrienne

I Have Change Spark Plugs, Starter, Alternater, Fuse and the just will not turn on the engine wont even turn over

Check and test all the following: The starter,park and neutral switch and ignition switch

The 8th digit tells me what engine you have with your car there is the same size engine one being super charged one isn't the letter you gave me tells me you have the non super charged engine.That was just in case i needed to know so i could get you the correct info.I don't think it is going to be a really expensive repair the main thing is to get it diagnosed right now.Let me know what you find.

This buick has a security system don't know the name of it but you have to put the code in the radio in order to unlock the system and the car turn over made sum noise but did not start but my sister put and music cd in and the car does even turn over it just show error on cd player and keeps making noise and one you turn the key it just makes a click noise with a beep. But does a engine do that when it is locked? or sum thing wrong with the cord from the start to the batteery?

I emailed you the location of the pcm and the decoder module.

Engine Mechanical problem
1994 Buick Park Avenue 6 cyl Two Wheel Drive Automatic 130k miles

My car will crank, but it wont start. I have fuel, but i heard it has something to do with the spark. If that were to be the case, what should i do to get it fixeD? just replace the spark plugs? if its not the spark, then what should i do?

check your ignition module/coilpack to see if you are getting spark, then take it from there .

Have a 1997 buick park avenue was driving down the road and heard a loud noise and the car cut off. Tried to start car back up and would not turn over. Then noticed that coolant was coming out heavily.

Try turning the crankshaft manually, can you do it -if not could be siezed up hydrolock or it thrown a rod thru the cylinder wall

Okay, I am working on a 1996 buick park avenue ultra. The owner said that it died at a stop light, he tried to start it again and after several cranks it eventually started up again. He drove it home and called me to come take a look. A few days later I arrive to diagnose the problem. I ask him to try to start the vehicle. It starts right up and sounds like it is running perfectly. I have him turn it off and restart the car and it just continues to crank without turning over. He continues until the battery is almost dead and still no start. I am getting spark to the plugs and plenty of fuel pressure from the main fuel line. I changed the plugs, which were all consistanly carboned up, the fuel filter by the tank. Still no start. When cranking the engine I am hearing a unique sound. Sort of like rur,rur,rur,rur....... 3-4 sec. pause rur,rur,rur,rur.......3-4 sec. pause rur,rur,rur,rur....over and over consecutively with my jumper cables connected. I have thoroughly cleaned both battery post connections as well. Also I have a blinking security light on the dash that the owner claims always did that, but I bet he is not totally sure about that. The dummy lights seem to be flashing speratically as the engine is cranking over. The supercharger is spinning with little resistance as it should with the belt removed and the oil level is full. I am at a total loss as this engine does not have the conventional distributor, but rather electronic ignition. No check engine light is coming on, so I have not pulled any codes as of yet. Should I anyways? I am not sure what to diagnose next but I am committed to finding the problem and am experienced with an ohm meter and would love to get some direction on where to look next. Thanks a million!

Yes look for codes need any clue you can get. fuel pressure should be 48-55psi check it out. Also pull plug wire hold 1/4" from block crank should have blue/white spark. let me know

I am getting a strong spark by this method, and what seemed to be a lot of fuel pressure after removing the main hose from the tank. If you were going to inspect and test the crankshaft position sensor, camshaft position sensor, the ignition switch, coils, and control module, what would you start with? Also, as items check out okay, what order would you inpect these items (time saver). Finally, do you think that I am on the right track? Thanks a million, I really appreciate you taking the time!!!!

With presence of spark crank, cam, coils, module are functioning. spray carb cleaner into air intake crank if it fires then fuel is problem.

This car will turn over, but will not start. I thought it had something to do with the ignition switch, so I bought a new one. The key that came with the replacement did not contain the "chip" in the original key. I went to my local dealer, and had a key made that has the "chip" on it. We drove the car for a half a day, and had no problems. Now, it is doing the same thing again. I have noticed when the security light is solid the car WILL start. When the security light is blinking the car WILL NOT start. Any ideas what I can do now?

By the way, I also pulled the serpintine belt from the supercharger, and the pully spun with seemingly the appropriate resistance and the oil was at the correct level. I will check those electronic items off my list, that makes good sence to me too now. What a time saver, thanks a million. What do you think about the security system being the culprit? I will get back to you after I pull codes and check the fuel pressure. Thanks again.

The only suggestion I have it to take it to the dealer and have them diagnose the problem. They are the only ones that will have the needed test equipment to diagnose and repair a security system problem.

Just sprsy into super it will get to cylinders

[quote:35435ecd88="Docfixit"]Just sprsy into super it will get to cylinders[/quote:35435ecd88] okay, I definately have spark to the plugs, although it is of an orangish yellow color instead of blue/white. I definately have plenty of fuel pressure to the fuel rails, but I have not checked beyond that. I sprayed starter fluid into the throttle body and the vehicle still does not start but does turn over. I am at a total loss!!!! Any other ideas?

Orange not good weak coil need to replace

the car will crank over,is getting fuel but no spark from coil pack,i replaced coil pack,crank sesor,still no firing from coil pack

Check the electronic spark control mod, on right side of the firewall, Testing info emailed!

[quote:adcc66a2f0="Docfixit"]Orange not good weak coil need to replace[/quote:adcc66a2f0] Okay, replaced all three coils today with new ones. The Buick still cranks and still does not start. I did a "screwdriver" test with the spark plug wire and am still getting the orange/yellow spark even with the new coils. What else would cause this weak spark, and would the weak spark be enough to not allow the engine to start? Thank you in advance for your continued advise and help.

Ignition module or PCM assuming no woring problems are present.

Thank you in advance for your continued advise and help.[/quote:ccecdd6c6b] update...decided to change the crankshaft position sensor. When preparing to remove the harmonic balancer bolt I found that the bolt hold come loose and cracked the harmonic balancer near the keyway, offsetting the the crank sensor and creating the weak spark. Thanks much to docfixit for leading me in the right direction of a weak spark that lead me to the problem. Hat off to you docfixit, thanks a million!!!

That's great news sorry I was outof town Fri thur Sun. And was not able to respond to still weak spark condition. My hats of for following through to crank sensor.

My hats of for following through to crank sensor.[/quote:c2702cbd82] Thanks for the congrats and all of the help on this project! One last question for you on the subject. The woodriff sheared off when the harmonic balancer bolt came loose. As you could imagine, I am having quite a struggle pulling the remaining inch of the woodriff still in the keyway. Any tips on extracting that from there besides pulling the engine out and tearing it down to remove the crankshaft......(fingers crossed!!!)?

Try a punch tap on end of key it is cresent shaped so the backend should rotate up so you can grab it with needlenose.
