no crank, no start?

Hi,

Does the light stay on solid, or does it flash? Also, have you tried a different key?

If you have, we need to scan the can-bus to see if there is an issue with a module. CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link showing how it's done:

Let me know if that is something you can do or have done. Also, let me know if the starter is engaging.

Take care,

Joe

Hello Joe,

If it's okay with you, I'm going to use lower case for responses.
Yes, the light is solid when the key is turned. I've used these three tools, two of them to reprogram my original keys.
i have tested the battery, actually everything works under the hood except the PCM perhaps. don't take my word for it. i removed the immobilizer and switch. but not the actuator.
i don't know if the PCM is bad or the immobilizer and switch.

Hi,

I attached the directions for programming keys with the immobilizer module. Take a look through them and let me know if you are able to perform the procedure.

Take care,

Joe

See pics below.

Hi, is there any way you could help me or teach me how to test the ignition switch before i put everything back together? Also, how do i install the immobilizer? I'm having trouble with it because the key release button is in the way. i don't remember how i got it out. everything on YouTube is bypassing the immobilizer. couldn't find one that was installing it.

yeah, disregard the immobilizer. i figured it out. the switch is challenging to install.

Hi,

Do you have everything reinstalled? Is it working now?

Let me know.

Joe

Hi Joe,
I still have to install the switch. It's a bit challenging-trying to find out how to install it from YouTube. I don't think there was anything in my Hanes Jeep book. I'm also going to see if I can find anything in my two other resources. 2003 jeep KJ Service Manual.pdf
Engine03jk_PARTS_FICHE.pdf
When i get the switch back on then i can try your recommendations.
Do you have any ideas how to install the switch. Because i don't want to break the plastic stick and the u shape metal, it seems that the u shape metal breaks easily on the actuator. So, i have tried a dozen times with no luck going in the switch properly.

Hi,

I attached the directions below for the removal and installation of the switch. Take a look through them and let me know if they help.

Take care,

Joe

See pics below.

It didn't work. i really don't understand why or what is broken. I know how to program a key. i tried to capture every step i did so you could see the error. I took 34 pics. i don't understand why it will not start. I did other scans also just to see what would happen and every scan gave me an error. i also tried the SBB PRO2 and it didn't even come on.

i just checked the fuses inside the jeep with the key in the on position and none of them turned on the light in the tester. the obd didn't come on with small obd reader. But when i turn the key everything lights up in the console.

i just tried to start the jeep and of course it didn't start but the mileage light was on with out key in it. maybe a minute then went off.

Just keeps getting worse!

Thanks for all your help i really appreciate it.

Oh, by the way, my high beam light comes on when i plug into the OBD. I don't know why. sorry about the pics being upside down.

Just some more pics. I'm not going to send you all of pics.
if you want a particular pic let me know and i'll get it for you.
I have to flush the radiator on my other Jeep.

thanks.

Hi,

I went through the pics with the computer upside down. LOL It doesn't appear you missed anything. Is it doing the same thing?

Joe

I don't understand what you mean by "is it doing the same thing?". It's doing the same as i mentioned above. if not worse. I also don't understand why i have to keep entering the vin number over and over. then getting errors when i run the key immobilizer test or any other test. the other tests also error out. do you think my XTool is not working properly? I also don't know why my dash lights come on but the fuses don't register. I only tried to do what you told me to do and now the fuses don't work. i wonder if there's a relay for the fuses which i can test. How do i fix this issue? i would think that's the number 1 priority. because i can't check anything in the jeep if the fuses don't work.

On a side not on Friday I was installing the thermostat housing on the other jeep and i guess i tightened it too hard and it broke. I wanted to go to Home Depot to get a clear vinyl hose so i could clean the heater core also. Now i don't have anything to drive.

Joe i noticed you sent me a email at 12:34 A.M, where are you at? Just wondering.

Hi,

I'm on the east coast. I work two different jobs. That's why I'm on so late. Just trying to help others but can't get here until late.

What fuse isn't working?

Joe

Hi Joe,

You're not in Fairfax, VA by any chance? "That would be too good be true". that's great man. i believe all of the fuses on the driver side panel. I can check them again. As much as i don't like to do this, should i disconnect the battery, and computer for a while, then reconnect them to see what happens. i don't remember where i heard this or if I read it somewhere. that if you disconnect the computer so many times then it stops working and the dealer has to reset it.

Thanks,
d

Hi,

Not in VA, but not too far. LOL, I'm near Pittsburgh.

As far as disconnecting the battery, that won't hurt anything. Actually, once it is disconnected, you can take the positive and negative cables and tie them together for about 15 minutes. That drains power from any capacitors.

Let me know.

Take care of yourself,

Joe

So, nothing has changed, the car still hasn't started. i'm at a complete loss. What can i do next? Please help me.

How would you know if the computer is bad? I don't think the computer is bad, because it lights up everything. The immobilizer and switch seem to work, I think. It's that key light in the dash still comes on and i think that's the problem.
when i tried to use the XTool tablet it didn't recognize the car at all. You have the pics i sent. Other ideas from anybody.

Thanks,
d

Hi,

If the scan tool didn't recognize the vehicle, there could be an issue with the powertrain control module. I am going to ask the site owner for his input to see if he has any other ideas.

Take care,

Joe

Ah, PCM is the computer. I thought the computer was ok. It turns all the lights on and tries to start. But I don't know. I'm so frustrated that i can't get the jeep to start.

When i start a vin scan i have to manually insert the numbers and the scanner doesn't keep it in its memory. Maybe I'm doing something wrong and it doesn't keep it memory.

My SBB Pro2 used to recognize it and now it it doesn't. Because I started to use the XTool. so i thought the scanner/XTool might be not working properly. I hate to ask you this, is there someone during the day can also assist me.

Can you consult with other co-workers/experts.

Thanks,
d

These are pics from last October on the SBB PRO2. That's my fuse box in the car.

Hi,

I have a feeling it is the PCM, but I will ask the site owner for his opinion.

Joe

Yep, I would check for power and ground at the PCM, also when you try to start it does the security light flash? Here is how to swap out the PCM and the wiring diagrams with a guide to help you with the testing:.

https://www.2carpros.com/articles/how-to-check-wiring

You can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know how it goes

The security red light does not flash. The key light with a line through it comes on and stays on.

Yes, I have a few of them. They're in this thread up above with the error's pics and so on. I appreciate the wiring diagrams but i don't know anything about electrical stuff. I was trying to take a beginner's course on the subject. But I'm too old for that. It all sounded like mar chin to me. I guess 58 is not the age to learn mar chin. I can check voltage on a battery but that's about it.

I see the battery voltage at 10 volts. can you confirm you have a good battery?

https://www.2carpros.com/articles/car-battery-load-test

Please go over this guide and get back to us.

Yes, it's a good battery. I don't know why it shows 10 volts. My small OBDII always shows 10V. If i use the voltmeter it says 12V and I'll charge it. I have a charger so I can charge it. My car has not been driven for a long time, so I make sure the battery stays up to its voltage. Do you know of a scanner that can program my PCM with my VIN? I'm returning the XTool scanner because i was out there working on the jeep for hours and I got nothing to work on the XTool. All I got were the errors. They're on the pics I sent on page 1.

I can't do a load test. My battery is good. If not, I'll charge it. I'm going to check the battery now. Charging it as well. I don't think pics from the scanner are going to help.
The light in the car works but not the low or high beam and the horn doesn't work when i lock the car with the fob. The flasher works.

I think the VIN got erased from the computer!

Hello,

Can anyone or everyone recommend a good car scanner? The XTool D8 didn't have a lot of options for Jeeps and my Jeep still hasn't started.
thx
d

I will forward this to one for help with the scanner.

Can the PCM, ECU, and ECM mean the computer? Can it be reprogramed with my VIN, so I know the car will run then. "Just put my foot in my mouth". I'm quite certain that I may have accidentally erased the VIN with the SBB PRO 2 tool.

Yes, PCM, ECU, and ECM means the main engine computer, you can get a preprogrammed unit by searching Google or Ebay.

You know I would consider getting another computer, but the jeep wants to start and i have the cabin lights coming on. I'm sorry, I'm just trying to figure out if I can reprogram the vin number and i would hope that it starts. I don't know much about car computers. I think that if a computer is on the fritz, it would ruin everything or not. Sorry, I'm just one of those people that has to find out why, why did this happen to me. It's also educational for me. So, is there a way to reprogram the VIN back into the PCM?

Yes, you need a scanner capable of doing so, you can search Google for models.

Well, I was wondering if perhaps you could suggest some. I wouldn't know one from another.

Gotcha, they are expensive, here is a scan tool that can program the PCM that I can recommend for $2,100.00.

https://amzn.to/3pt4Zz2

These units can go as high as $5,000.

Yeah, that's out of reach for me. Money is a big factor. Disability doesn't give you much. I Don't know how I'm going to get the jeep running.

I would get a preprogrammed PCM by searching Google or Ebay. Much more inexpensive, especially if you are going to use it just the one time.

I got a new PCM and replaced it with no change. The PCM is not the problem. My car is still not starting.

Not cranking over or cranking and not starting, also please clear the codes and try to start the engine and rerun the codes, can you please send a video of the engine cranking over if the engine not running is the problem. Please upload pictures or videos of the problem so we can see what's going on.
