I am really stumped and can't afford a mechanic. My truck died while driving and had it towed home. I have replaced the plugs, fuel pump, timing belt, spark on driver side (can't figure out how to on coil packs, but i assume if the driver side is working than the passenger side should be. once or twice it would fire but die right away except one day after replacing the coil packs and reinstalling them because the ones i got threw codes the truck fired up and ran like a charm till i gave it gas. Than it ran like crap and now it wont start again. Need help
