fp is too low. spec is 41-47 for the prime. thats the sign of a weak pump or a line restriction. check for kinks or leaks, and change the filter if you havent already. then check the fp pressure again.

I do agree... The Pressure is Low...

My Old Bonneville specs out lower than the 95 SSEi and I am producing more pressure than you currently are...

Your FPR is working properly.

Either your fuel pump is bad, your filter clogged, or you have a strainer sock (on the pump) filled with debris. If a filter change doesn't improve it, replace the pump and sock (they come together). You'll need to purchase a tank seal seperately.

put new filter on and the car will go now. but pressure is still low .
1.38 .lb. prime
2.34 .lb.run
3.42.lb.fpr unpluged

what is the scale there? and thats in psi?

[willwren]

That is PSi, and your're still low, but it helped.

You need to drop the tank and change the pump.

Any auto parts store pump will be fine, looks like Autozone has it for $215

If you have time to wait for one to be shipped, RockAuto.com has several options available from $109-137.

Also, if you are in a pinch, a used pump from a junk yard will do the job just fine...
