1995 GMC Jimmy.. brand new battery... has problems starting. ...but it just makes THIS sound and will not start. started once before and made an ... GMC Jimmy \ Chevy Blazer Fuel Tank Removal -Fuel Pump Replacement ...

Thye fuelpump relay is located to the right of the brake booster. this is for a 1991 gmc jimmy (s-15)

I have enclosed a diagram to help locate the relay.

The most common reason for no fuel pressure on these trucks is not the relay but rather the fuelpump itself. the pump is located inside the fuel tank.

There is also a problem with the wiring to the fuel pump, you will need to locate the top of the tank and then off to side of tank is wiring .
This wiring comes off the top of the tank, you will need to check and there is connector problems..
there is one or two ground wires that come off wiring to top of tank which run to frame, check to make sure the grounds are good. if you end up with a bad pump you will see a notice to rewire a new fuelpump connector. hope this is helpful. good day.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????

Fuel pump relay inside the glove box is kaputz? http://www.ehow.com/how_5486354_replace-jimmy-fuel-pump-relay.html

Unfortunately your fuel pump is in your gas tank. I have to do three of them - tons of fun

check your gas. did you get fuel at a different location than you always do? if it's not the gas then your fuel pump is going bad

fuel filter has no fuse. Do you mean fuel pump or fuel pump relay fuse?

Relay - Fuel Pump 1991 GMC Truck S15 Jimmy 2WD 4.3L TBI 6cyl The Relay - Fuel Pump Under hood, driver side, upper firewall, mounted in relay block

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.

Hi

A very common failure on these is the CPFI unit , or SPIDER as people like to call it.

There is one single injector which feeds each cylinder via a pipe and poppet. The injector becomes blocked and the engine won't start or run.

Before you go condemning this though, just make sure you have good fuel pressure because the fuel pressure regulator or fuel pump could also have a hand in the problem. Make sure the pump is running, and if not then check the fuse, the relay, and the pump itself.

Very best regards
