Im not sure if its my fuel pump or not but i know my car is getting spark and its also in time im positive of this. When i turn my key i cant hear my fuel pump prime not it was working on/off for alittle while. Like it would work for alittle while i was driving and then boom nothing no fuel i could hear it prime or run at all. I have a hyper tech ecu chip thats about the only mod electrical wise.Im gonna use a volt-meter tomarrow and see if its gettin anything if not guys any suggestions on where to start first????Is there some type of fuel silenoid i need to check out???? Have any of you guys ever have this problem???

 

take the chip out and try again

 

I f you can't hear the pump run then check the fuse in the fuse box..it's a quick easy check after that grab a test light and go back to the back of the car and reach up if you can and un plug the harness connector and test for power and ground.......what I do is loop the test light in series with the power and ground that way it'll kill two birds with one stone...have some one turn the key on and if the test light lights up then goes out you know the integrity of the circuit has potential to operate the pump.....what I'll do next is have someone crank the engine with the test light still in line and watch if the test light lights back up and stays lite while cranking......if it does then the circuit is most likely okay ..then plug the connector back in and if you don't hear the pump while performing the same tests but with the connector plugged in then most likely the pump is bad.....however if you don't have power back at the harness connector while performing the above tests then you'll need to trace the circuit via a diagram... the fuel pump relay is under the drivers seat.

 

nice thanks guys ill go snag a test light tomarrow i tried with the chip out no difference

 

id check the fuel pump inertia switch in the hatch, .trunk. Use a piece of wire to bypass the switch

 

did it already. Im thinkin it may be a wireing problem because some freakin a-hole decided he wanted to put a super bad-*** stero in it but i dont see how it can work 1 second and then die the next i dunno im gonna check.Im gonna check the switch under the drivers seat and then check the wires for good flow.

 

ok its fuel pump checked the fuel cut off swith wires and i had power so its good.Now i have a question what is the stovk size fuel pump im talkin LPH does my 92 HO gt come with???WIll i have to get a FPR if i get a upgraded fuel pump like the 155 or 255 if so what else will i have to get to go with the FPR

 

stock was 88lph...most will tell you if you plan to upgrade alot in the future just go with the 255lph......if you don't plann to supercharge personally I think the 155 or 190 is just fine if you want to get an adjustable FPR go ahead it's a good upgrade

 

well i plan on goin nitrous or maby boost but nothing major. Will i have to go to an adjustable FPR if i get a 155lph pump??????

 

when running nitrous as I am it's always a good idea to bump up fuel pressure expecially if your running a dry kit but I suggest running a wet nitrous kit as it adds fuel and nitrous not just nitrous as for boost it depends on how much you plan to run as far as how much you'll need to upgrade the fuel system but just do the FPR it's a beneficial upgrade
