1998 mustang gt fuel pump / pressure issues
I am trying to help my sister with her 98 GT, 100,458 miles. I am looking for some input on the pretty consistant starting issues it is having.
1st thing in the AM, starts up ok. Drive it anywhere, even short distances, then it will not re start (engine just turns over). Sometimes it would start after sitting awhile. To date it has only died while running 2x.
I suspect it is fuel related. Here are some additional symptoms I noticed.
I don't see much fuel pressure, I press the Schrader valve on the fuel manifold and there is never anything there. The only time anything came out was when I pressed it while the engine was running (fuel of course came out).
I checked for voltage at the wiring at the back of the gas tank, looks good.
I sat under the car and had my sister turn on the ignition 5 times, I heard the fuel pump prime each time, wouldn't start after priming. Had her try again and quickly crank it over before the priming ended and it started.
Let it run a minute or two and then just turned the ignition on and the pump did not prime anymore.
I searched and read what I could find here and in other places, based upon that and the symptoms I noticed, I suspect the fuel pump is only working intermittantly.
Is that probably it or is there anything else to check like a clogged return line?
Thanks for reading.
