88 blazer tbi problem
i got a 88 gmc 350 tbi i just bought. it used to be a buddys, When you started it it would run for a few seconds and die. if you held the throttle down it would run and act as if it were loading up. He put a fuel pressure regulator on, fuel filter and plugs. Now it will start for about 2 seconds and dies, after those few seconds its not gettin fuel to the tbi unit.
to me it sounds like a fuel pump. anyone got any ideas? |

Re: 88 blazer tbi problem
sisters 91 rs started doing this as well, but new fuel pump (2 years less than 10k miles). Started every time till we let it sit for a couple months after she got T boned, then needed to move it to get the trailer out, and wouldnt fire, primed it and she ran, but then died out.

Re: 88 blazer tbi problem
#1 SIGN A FUEL PUMP IS GETTING WEAK FUEL SMELL ON THE PASSENGER SIDE THRU THE FENDER U CAN SMELL IT WHEN U OPEN THE PASSENGER DOOR
 Yeah Sounds like the fuel pump i have had 1 of my 87 trucks die out in the drive way and then not have a problem for a week than i parked it and it wouldnt crank lol i have 3 tbi trucks the fuel pressure is suppose to be 13-15 psi ideally 14 constant would be great but they go up and down the psi isnt constant u can put a FP reg and put it all the way to 15 but no more or u will have more problems
