Dont entirely right off the fuel pump yet.
Get the fuel pump test gauge with the TBI adapter.
I believe OReillys loaner has that.
If not, Harbor **** tools is now selling a kit that looks like it has a TBI adapter.
Use a new fuel filter.
Install the guage inline with the filter plumbed in the right direction and the gauge measuring output through the filter.
Find pin "G" on the obd 1 port.
Be very very carefull to not touch anything else.
That port goes to the ECM and if you **** it up you will fry the ecm.
Put 12 volts to it, Look at the pressure and the timing of that pressure.
13 to 15 psi in about less than 10 seconds.
Including pumping out the air.
Probably a good pump.
But on the margine of a long run time.
And dont discount the fuel pump relay either.
They have low volt intermittant contact problems where they internally melt and cause wild and unpredictable random voltage loss.
