Aight, here's the deal, i am officially lost now, the truck was acting up every now and then, driving down the road it would just shut off for a few seconds, and then get goin again with out me doing anything. Well, it finally died on me a few weeks back, wouldn't start, i didn't hear the fuel pump in the tank, which i normally could, so i just figured it was dead, Autozone crap, almost 3 years out of it, figured as much. Was under warranty, free replacement,,,didn't work,,,replaced the pump relay,,,worked for awhile, got in it the next morning to go to work,,,no start. Not seeing any fuel spray from the injectors, i try to start figuring why no pressurem changed out the oil pressure switch,,,no go,,,fuel pressure regulator,,,no go, ECM (have a friend at the zone let me try it) didn't work, luckily these parts i oaid for, are not that expensive, but it came down to the injector itself that was bad, replaced it with another Autozone crappy,,,,,,runs,,but like crapola, very rich, idles poorly and the spray pattern just wasn't uniform. Took it back to "the Zone",,, went to Napa, paid like $150 for their top of the line, "new" unit (which BTW, looks identical to the stock unit).....same thing, alittle better spray pattern but still looks like it is "building up" seeing a few little dropletts going shooting off to the side every now and then. Just thought i'd post up here, and see if there is something i am missing, or forgetting to do, i am pretty knowledgable with this engine and truck, but this one just has me stumped, if i had the correct dianostic tools, i may have been able to finger out the problem first off, which i am working on now, got the laptop, just need the cable Any other idears??? what am i missing?? do i need to reset the timing or something, the throttle response it a bit better than before, but that could just be from the extra fuel it's dumping. It DID just start throwing a code 45, which i would expect, rich condition/oxygen sensor thing, did some weird idle thing, up and down a few times, then coded out. ANYHOO, talk to me fellas, and chickas? EDIT: to give you an idea as to how it idles, it runs like it has a big cam, loping, smokin out the back, pretty steady lope too, not like an intermittent misfire.
