OK...so you have THREE PROBLEMS....no spark at the coil or plugs? No fuel pressure at the schrader valve and no signal to the injectors. What brought this on?

These engines are all about electricity. They need it everywhere all the time. Start with fuses and grounds, grounds are mucho important. Listen for relays to click. Get a wiring diagram, if you need one let me know. With this many failures I guess it could be the ecm but that's not real common.

Read the wiring diagram and start tracing.
.

Check the "kill" switch. On the passenger side floorboard is a little black box with a button on top. Press that. Did the truck take a hit and just die?

The EEC power relay provides power to every problem you have. Start testing there!

fuseable link going from the selenoid to the #1 post on the "computer" ... thats what happened to mine.. no spark no injector pulse,, no fuel pump.... It was right near the selenoid.

that was my first truck and i put 280,000 miles on it so i got to know it pretty well lol!! great lil trucks. well x2 on the fuseable link it happened to me twice and the fuel pump relay went at the same time. both times with no warning. also ive heard that the ground in the computer sometimes goes haywire, cant remeber what pin it is but a wire dia. will tell. good luck

thanks for the replys it turned out it was just the comp power relay

thanks
