I just replaced the fuel pump in a 1994 GMC jimmy. Now the engine does not get fuel. I disconnected the line at the back of the engine and the fuel runs out, but the engine itself is dry. If I put gas in the throttle body the engine will run for a few seconds then dye. What I should I try next?

Re: No fuel to the engine
'puter wont deliver fuel if oil pressure switch is reading bad weak or faulty..or if ignition is not sending proper signal to 'puter....on the mechanical side...you could have a bad fuel pressure regulator sending all fuel right back the return line and not into the engine/ clogged fuel rail due to using some sort of nasty fule injector cleaner than turned the lines to jello inside..etc .etc.

i have a 1994 gmc jimmy 4.3l cpi. i could not pass the emission test.hard to start, spuddered, and smell of gas was strong. long story short, i replaced my spider injectors, good to go. $278 brand new from auto zone.
The pressure relief valve is in the spider fuel injector not the fuel pump. We have had our 94 gmc jimmy for 4 years & have had to replace the fuel injector 4 times which cost right at $500 each time for the part. Yes the spider fuel injector cost averages around $500.
