The car does not start

Will the starter crank? One possibility is the security system. I'm not sure what you mean about computer not showing anything? If you used a scanner that showed live engine data, it should have showed plenty. If you can't communicate, maybe something wrong with the datalink connector?

When i got it it would randomly cut off i replaced distributor ignition module and coil worked great for about 2 or 3 months. it shut off then came back on while i was goin down the road then the next day it cut all the way off an would not start back up. 2 days later it staryed back up an has been fine but i have not been driving it much due to not knowing if it is goin to cut off and leave me settin this is tje second one i have owned that is doing this an im stumped please help if possible also usually before it messes up i have noticed a kind of burnt smell

scan for codes and check fuelpressure with a gauge auto parts rent them.

Code reader pulled catalyst codes 0420 and 0430 isnt that the converter or exhaust system?

those are both converter problems could be the converter or an O2 sensor or an air leak in exhaust before converters. have a pro scan it as he can check to see if it's the converter or not. but it's probably the converters are bad.it's about $415 for both converters which you will need at rock auto less shipping.

Do u think those things could be causing the car to act how it has?

likely check fuelpressure as well though. auto parts rent the gauge.

Okay will try thanks

Electrical problem
1995 Pontiac Trans Am Two Wheel Drive Manual

when driving the car will just cut out the lights and radio all still work and the car will try and fire up but it just will just keep cracking. then when i let it set for a few min it will restart and drive fine till it dies again.

Hi, If it cranks good but won't start, when the problem occurs, have a helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. How long since a tun-up? You need to test when the problem occurs.

My car does the same thing. Maybe look into the Egr Valve..

Did you ever get a chance to do any testing?

when you turn the key it acts like its not getting spark i have checked all the obvious grounds and battery connections even had the starter taken off to be checked and it came back good four times any help?

Ok--i reckon you don't mean "no spark" (associated with turning over and no electricity thru the spark plugs)

The way i read this is, when you turn the key to "start" absolutely nothing happens.

Please read my answer in this link.

I am assuming that the wiring from the key down to the starter relay/ solenoid is good,

And the neutral safety switch is good too.

If this does not help, return and we will continue.....really give it your all. There's nothing like going thru a million motions, and finding out it was something overlooked days ago

Return with a voltmeter, someone on your end able to use it.

Missed that--has the battery been tested?

Headlights work good?

The medic

on my 94 trans am firebird. i turn the key and the starter turns fast but it jults on and off really fast. the battery connections are good and clean..... could it be the solinoid?

Drop the starter motor and get it load tested-sounds like the overrunning clutch is slipping-

were is the overrunning clutch located at? is it in the starter?

weres the overrunning clutch located..... its on the starter right?

Engine Performance problem
1993 Pontiac Trans Am V8 Two Wheel Drive Automatic

My car will start up fine but after running for awhle it will stall and wont fire up unless i let it sit for awhile engine cranks but dosent seem to be getting fuel any ideas?

Welcome to the forum, engine cranking, do you have spark at the plugs? Are there any trouble codes? Use a gage and check fuel pressure.

Its looks similar to this in the starter motor-

Yep. thats what it was. Thanks.

my car will not start it turns over and cranks It will run for a minute but then it cuts back off. It has been sitting for about a year changed fuel filiter starter, and ignition but I don't know what to do at this point. Do you what the problem could be. I am stuck and not sure what to do at this point.

scan for codes and check fuelpressure first. should be 41-47 psi cross a&b on aldl below lh dash by steering column count light flashes in series of 3 if it's 12 that is normal for key on and reading light.

I replaced a new fuel pump and filter and also a fuel relay charged my battery full and it sill wont start.. It turns but doesnt start. ? What could it be ?

scan for codes, and check fuel pressure first. check to see if you are getting spark.If you think it is a fuel issue, use a gauge and check fuel pressure. If it cranks good but won't start, have a helper crank it, while you visually check for spark at the spark plugs.

I have a 1993 Trans Am, after I installed headers I noticed that the car started running ruff and hesitated when I accelerated. Need help please, what should I do. Thank you so much in advance.....

Where O2 sensors installed?

Good question, I'm not sure unfortunately I did not install the headers so I'm not sure where the 02 Sensors were installed. I have uploaded some pics for better view. Thanks you so much....

Going to need to jack up and see if O2 is installed. Also check for codes find ALDL under dash next to column.

jumper from term A to B key on engine light will flash. so flash, flash pause flash is 21. post codes
