Well, the inevitable happened, "my 92 tracker rolls over fine, but won't start".
Yup. I happened yesterday morning, but it did eventually start within about 10 miniutes. So, I put some gas-line antifreeze in with some gas and away I went to work. Started fine last night again. This morning, it wouldn't start, after about 30 miniutes of trying, I gave up and took the car out to get to work. I've been reading that the ECM is a very common problem to this situation. I need some info on jumping the fuel pump, and possibly ECM location and removal.
If anyone can help, that would be great.

The only thing that has changed, is last week I used seafoam in my gas tank to try to improve fuel consumption, otherwise it ran great.

What is this seafoam stuff?

It's an engine cleaner, but you use it in your fuel system, crank case and you also suck it in through a vacuum line for a full cleaning.

wow this sounds exactly like mine did ......first thing you have to check is for the fuel pump working listen for the pump to prime when you turn the key to on ....then if it is not spinning got to your harness behind your left rear brake light and disconect the large harness.... the connections are most likely green...... clean these up or if ist is really bad cut them out of the harness and solder and heat sink together.....

this was the exact same thing that happened to me and i wasted $255 on a fuel pump....

If you here the fuel pump for a few seconds when you put the key in the "on" position it's most likely to be the ECM. The ECM is located behind the fuse box under the drivers side dash. It's held in by 2 screws on both sides if I'm correct. Have a look under there it's pretty logical  .
If you are able to get one from a fellow zuker with the same motor you have you could try to swap it over quickly and see if that's the problem

Truck started fine this morning and I drove it to work. I removed the ECM and one of the tech's I work with looked at it. We didn't see anything wrong, it looked perfect. So, we decided to replace the caps anyway while we had it out, plus, we had them here at work, so no cost to me. The first one he removed started to have a horrible smell as the solder iron heated it up, John,(the tech) said that's a sign of a bad cap and would cause something in the circut to be intermittent, which was my problem. When it was removed, there was a little corrosion on the board that can't be seen unless removed. So, hopefully this will be what was wrong.

Unseen corrosion

Sorry for the shaky pic

There looked to be a couple cold solder joints in this area, John(tech) re-soldered all connections.
