Car Still not starting

[christiane]

Ok, I have posted this before and thought I had found the problem, but the car is still not running.
Here is what happend:
After getting some of my suspension work completed I drove the car from the garage to the driveway in front of my house in order to free up the garage for my other project. Once I got there I noticed that my A/F gauge was reading 0.000. So after some investigating I disassembled the wiring harnerss for the O2 sensor. Somewhere in this disassembly the 12V + wire grounded out. After this the car would not run correctly at all. like it was missing and would not rev over 4k RPMs. Then finally it would not start at all.

The car was and is getting spark. It is also getting fuel to the fuel rail. I checked with a noid light to see if the injectors were firing and the light did not illluminate. So I know I am not getting fuel into the combustion chamber.

I knew the car was going to be down for a while so it wasnt really a big deal as I still had to install the sway bars, and motor mount inserts. To this point here is what I have replaced: ECM relay, Cam angle sensor, crank angle sensor, plugs, plug wires, and O2 sensor. I also pulled the ECU out to check to see if it appeared to be fried and it looked and smelled as good as new.

I am at my whits end at this point. I have a few more little things I need to do before I get the car back on the road but with it not running it doesnt make much sense to spend any time working on her . If anyone can help me to get this thing running I would gladly pay them for their time. I just miss driving my car (I have been driving a mercury Cougar for the past month while I was working on my car, and its just about to drive me crazy getting passed by riced out honduhs).

DSMwisemen please respond with any input.

I was out tinkering with the car this evening and noticed the battery was dead so I decided to charge it and give it another attempt at starting. Of coarse it did not start, but after I got out of the car to turn the battery charger down I did notice a relay apparently behind/ around the intake manifold that was clicking like crazy. Can anyone tell me what relay this would be?

Starter i just pulled my engine/trans and i did't see a realy of any type, only thing back there is the starter under the intake manifold. good luck.

Ok I THINK I have found the problem and the solution Dave with DSMLink said the following:

The sensor ground track in the ECU is burned at 2G ECU pin 92, near the board mountiung screw on the top of the board. Repairing the burned track is usually sufficient, but not always.

The ECU is shutting off the injectors while cranking because it thinks the TPS is indicating WOT, activating DSMLink's cranking fuel cut feature.

PM me about my repair service if you can't resolve this yourself.

So the ECU will be sent out hopefully tomorrow or Friday at the latest. Im just posting this in the unlikely event that someone else would have these same problems.
If this does NOT take care of the issue I will post back here. But this is the onlylogical explanation at this point. DSMLink's tech support is second to none!

Just wanted to post an update to my problem. The problem was just as Dave had mentioned with the burned track on the ECU.

DSMLink's support is simply the best I have ever delt with. These guys are amazing.
