3vz not even trying :(
so i desided to work on my other truck, 91 v6 manual, it cranks over perfectly fine, checked for spark, fuel pump kicks on with starter and with afm door, and worst of all the truck will not even spit when i spray starting fluid in her, any ideas?

need more info... timing on? good spark? good plugs? what fuel pressure at? is the cold injector kicking on? good compression? might be more just give us time to think...

Checked codes??
If no codes, compression okay, timing belt & ignition timing okay, good spark and fuel pressure, then computer must not be firing injectors. Check that they're hot when ignition on. Check that ecu terminals #10 and #20 are hot when ignition is on. See page EG2–194:

had a mechanic check compression as i havent the tools to do that, or so he said he did.
for the starting fluid or sometimes just gas lol i would pull off the pcv inlet into the intake hose and spray there.
afm door works and kicks on the pump when i open it, after cranking i can hear it flapping so its fine
havent had the chance to check the belts, or the dizzy for that matter, will do as soon as i get the chance, but i have had the truck run once for a little bit then soon shut off and wont start.
with IGN on the injectors are hot and # 10 ad 20 are hot, if i manually ground them i can hear/feel the injectors hit.
dont really have a fuel pressure tester either but the cold start kicks on as it should, and if i loosen the banjo bolt some it sprays fuel EVERYWHERE so i am assuming the pressure is good, havent checked FPR tho.
also the plugs are new and get great spark
i noticed when i pulled the ecu out it does not indicate 4X4 on it, would this have anything to do with it running? the truck is manual if it matters.
