There is no check Engine light. It just surges/hesitates under somewhat hard acceleration, and up hills. a light foot on the pedal it is fine.

see if you can fit a manual fuel gauge to the rail , then place the car under a load and see if the psy drops off ??? like a faulty fuel pump ?
if there is enough hose tape the gauge to the windshield and find that hill as your load , sounds like a junk pump my friend ?
your psi should stay 30-40 psi at all times .
hope this helps
I'm in tx but may be able to help over the phone ??
