I have a 98 transam in which I just replaced the fuel pump I had it running for a few days and i went to gas station to fill her up. When i went to start her up i can hear the fuel pump prime but it wont start. I have 12v hard wire to the pump So i know its getting power cranks but still wont start. Can anyone help please???

No codes as far as fuel is concern besides o2 codes. I went ahead and check the shraeder valve and it had no fuel going through it i was suggested changing the fuel filter. Inwill be doing so today. Pump still sound strong back there. I hopw the pump not fubar yet

Replaced fuel filter still the same issue order a new pump

Take it back out. Your line may have come off in the tank

X2. Even if your filter was clogged you would still have fuel to the schrader valve. Loose line is likely the culprit if you hear it priming but no pressure

What gets me is the 12v wire the grey wire wasnt sending 12v to the pump. I replaced it and ran a new line worked great for a few days and now nothing. I did trace the lines and seen no leak

zrultima

If there was a loose line somewhere i would have caught it ny now

Well guys reconnected every thing back together started right up now. One last issue is now the gas gauge doesnt work is there anything i can go to fix it

zrultima

Sorry to revive this but i would like to get a fuel pressure gauge that i can attach to the fuel rail i went to different auto part no one seem to know what i was talking about and guided me to the tester

Alright guys so the pump was only making 20 psi so I swapped it out for another one started right up but then when I went to go park it didn't start up again. it primes but wont start I open her up and notice that one of the black plastic tube in which what looks like a regulator had broken off

zrultima

Here is the part that broke goesinto one of the pressure lines

zrultima

Please anyone help this is my dd i dont want to get rid of it. It acts like its not gettig enough fuel but i know the pump working

Thats your return line with the regulator in it. Youll need a new one. Without it all of your fuel is comming back into the tank and bypassing the regulator thats why you only get low pressure then nothing. The other pump was probably good and you had a crack in the return line and when you replaced the pump it broke on off.

zrultima

But that was part of the assembly so it wont run without it???

I am running the walbro pump so i have to go find this at a junkyard

Yup, or you can make a WTB post on here and see if anyone has it. You can also run an aftermarket regulator if you want but replacing this would be cheaper

Also, next time post in the Fuel Injection section, youll get a lot more hits. Good luck

zrultima
