1999 Chevrolet Silverado, WONT START

[rhandwor]

I would ask for all defective parts as you can look over the job in your spare time.

Thanks for the update. WE all want to know what is going on.

All,

The dealer called today with the bad news. Apparently there has been a "short" in the door lock sensor and door lock module which caused the PCM to think there was some safety/security issue and keep the engine from starting. They are putting in a new sensor, and module, and fixing any damaged wiring and reprogramming the PCM security stuff.

I know that is not much detail, and I may have the terminology off but that was all I could get over the phone. I will elaborate more once I pick up the truck and get the final rundown. Bottom line was it was an electrical failure that caused the computer to not let the truck start.

Cost, 1200.00.

Not to mention the 400 I threw away on the pump I did not need.

I am going to try to find out the steps they took and the tools they used to diagnose the problem. I will try to get the bad parts.

I suppose that I could have saved some money by just having them do the troubleshooting. I could have went down there in the parking lot and replaced the stuff they said was bad....

Anyway, more later once I get it back.

Thanks for keeping us posted on it.
I think we all spent to much time on that fuel pressure.
To late now but go back and read no 5 post.
Did you notice your security flashing at you?
Let us know how it goes.

[rmweber]

No, my security light did not flash unless my door was open, which is normal I believe.

thx

The security should flash if it has a problem. But if it was shorted out that could have caused it not to tell you any thing.
When the security system trips normally it will start and run 30 seconds then shut down.
Did you get to try the carb cleaner test I suggested in post 16?
That one usually tells the story on the security system?
We hope the dealer gets it going good.
let us know how it goes.

Does anybody know what size resister is needed for pass lock. Also this door deal can it be jumped or does it require a resister also?

First would need to know which system CTD or TM.
But I do not think the resister by pass will work on ether one.
As far as I can tell door locks 3 wire switch that switches from a lock to a unlock signal to body computer.
I hope his dealer knows what he is doing on it.
Usually when a theft system trips in will start and run for 30 seconds.
And or run on carb cleaner.
And security light will flash.
Newer one or the CTD systems will flash head lights and blow horn and some of them will disable horn.
It was strange he did not have any of them symptoms.
But strange things happen or it could have been dead shorted.

I was wondering if you got your problem fixed??

I had my 2000 Chevrolet Silverado die on me here recently and we thought that it was the fuel pump, but it turned out to be just the coil. Thank God I didn't change the pump. Now it starts up with no problem.

Folks,

This is what my recipt said,

" Performed multiple diagnostics pulling apart many interior panels steering column covers and carpet and traced wires from pcm and bcm and determined that the rt rear pass lock module and pass lock sensors have failed causign wiring to overheat and cause connector pin concerns. R& R and replaced pass lock module and sensor. Repaired connector and reassembled vehicle. Recalibrated body control module and pcm and pass lock system"

The truck is now running. However, the dome light stays on all the time.

I dont know why, I thought maybe it was a pin switch, but I cannot even find any pin switches!

However, since this was not happening before I brought it to the dealer, i may bring it back and complain.

However, they may find something else that was shorted out and charge me another 1200 dollars to fix it....

And o by the way, they inspected the truck and found that I need all new brakes rotors and parking brake shoes, and I have some kind of seal leaking in the front axel. They wanted another 8 or 9 hundred to fix that stuff.

I declined. However, my parking brake does not work, and I think I will have to replace those shoes since it wont pass inspection.

Stand by for new post on how to do that.

Thanks once again for everyones help. Cheers.

Bob

Thanks for posting back how it went.
And we are glad they got the starting fixed.
It sounds like they had a tough time fixing it for some reason.
Makes you wonder how well trained them goodwrench techs are.
What did they charge for it all?

I think the dome light switch is on the door latch.
On some I have got a the working by spraying skunk oil on the door latch.

Good Luck

I'm glad they got it fixed but it sure took long enough. I imagine you needed a rental vehicle also or did the dealer supply one.
