92 chevy blazer will not start/run

Ok guys heres a Fun one.

I've got a 1992 Chevy Blazer S-10 Tahoe 150,000 Miles. 4.3l Mutliport fuel injection I think its a "w" vin #

Will not start just Click, Click, Click.

I've been sitting on this car for over a year with it not running. It's been to 3 mechanics and they can't get it running or if they do not for long.

The sad thing is its got loads of new parts it in. I'll try to type them all but i might forget some. The following parts have been installed by me or by a good mechanic.

Entire fuel injection system. Injectors ,spider system(twice) Computer(twice) All plugs wires etc. (starter is good) battery and alt are good. fuel pump(twice) filters and gas lines.

First mechanic say it was stalling because of the spider system needed to be replaced so he did and it ran good for a while. i got a few hundred miles until it just shut off while going down the highway.

2nd mechanic. Said to change the fuel pump and computer. (allthough I allready changed the pump.)I got a few hundred miles and same thing. It just died. then he found a "short" in the wiring some where between the fuel pump and the front of the car. Then i got 600 miles and it just shut off on the highway.

3rd mecanic scrathed his head for 3 months played with everthing changed the computer looked for a short and just told me to throw a match at it.

Its got a great body......clean interior....New 30" tires......New raditor hoses etc...etc.....etc......its just a shame to junk it.

When it starts it runs super super smooth and very very strong. I think my problem i electrical but I can't find it........it also throw no codes.

Any body have any ideas or stories that would relate please help me...............................Wife said shes going to divorce me if i don't move on or get it running.

thanks.....if i think of more i'll update this post.

The Clicking sounds like a bad battery or bad starter solenoid or bad connection between the two. H

I don't think so because when it does start it runs great then decides to just shut off..........like its out of gas or the ignition is shut off....allthough there is enough pressure at the fuel rail.....battery is good etc.....

UPDATE:................called another garage and it will be towed again in about a week.

I love GM products but they have the worst electrical systems... You have a wiring problem some place. As far as the start problem, if you are absolutely sure the battery is good and the battery cables are good then check to make sure the frame/engine ground is still intact. You negative battery cable probably goes to some place on the engine block (in most cases to the intake or heads) and then there should be a wire going from the block to the body/frame. It's clicking so that means the starter switch and starter solenoid are good. It would be my bet that the engine ground is shot. I would replace the battery cables and check all body/frame grounds.

good luck, mark

Ok....i'll try that...............I wonder if i ran a jumper wire from the negative to the ground on the engine then another to the frame...............if that will be good enough to rule out the faulty ground wires..........any way I'll try that tommorow morning.....gotta go to work

thanks

Bad ignition switch or the bulkhead connector on the firewall. Both can cause the symptoms your having.

bulk head connector?................is that where the fuses are at under the hood?............Not sure where to look at that one.??

The big connector that goes through the firewall. Usually behind the fuse box. Removable from the engine side. It connects the cab wiring to the chassis wiring. There are a couple connectors in there that sometimes get fried.

OK so far I've checked all the connnections and nothing obvious I've ran some Jumper wires from the battery ground to the frame.............then from the frame to the engine block and nothing....................when I first got to the Blazer I Jumped it with my Jeep...........it started right up.......but then shut off after about 30 seconds..............not stalled but as if the key was turned off. ( I jump it when Im trying to get it running cause the battery han'y got a great charge from trying to start it so many times......when I do get it running for a while the battery charges back up.)

I'm going to try and get under the dash somemore and check for rusted wires...........as far as the coil.......i replaced that a little while back. no difference.

Thanks guys..............keep 'em comin.....................BRIAN
