HELP!!!!!!!!!!!!!!!!!!! my GD engines not getting fuel!

so i replaced the fuel tank, fuel pump, ending unit, and fuel filter on my suburban....still no fucking gas to the TBI unit...what the fuck else should i look at?

???????

what year is it ? and what engine ?

dude..I had a similar thing over the summer on my Tahoe..turned out one of the fuel lines got caught on something and kinked it...like in the area where it goes from the frame up to the injector...have you pressure tested it at the injector?

its a 1993 TBI 350

this is an easy problem to diagnose. First make sure your pump is being powered, if you can connect your fuel pump to a power source manually and see if fuel is being pumped(you can just dump it into a can or something) if thats the case hook the filter up, again with the hose just dumping into a can see if the fuel makes it past the filter. If not well there you go, then check to see if that fuel makes it to the TBI, if so check those injectors.

those pigtails at the pump are notorious, did they give you a new one? also, you sure you didnt get a shit pump? are you getting pressure anywhere like lobdy mentioned???

i didnt check for that i got pissed and chucked a wrench down the street so i closed up shop for the day before i fucked something up gonna check it out tomorrow nite tho thanks guys! might have to Re-UP my membership if these tips dont work! LOL

well its a pretty simple design, i you pull the line right before the TBI manually power the fuel pump and no fuel flows and the pump is functioning then something is wrong in the lines. Clogged? Crimped?

they might be gonna check it out tonite...gotta GM certifed mechanic friend comin by too
