What happens when fuel pressure is at specification?
CASE 1: Fuel pressure is at specification This result confirms that the fuel pump is OK and doing its part. Also, this test result confirms that the following components are OK too: Fuel pump fuse. Fuel pump relay. Fuel pump inertia switch. And so, there’s no need to spend time testing them or money replacing them.

Where is the fuel pressure gauge on a Ford pickup?
Now, what makes testing the fuel pump pretty easy, is that your Ford pickup (van, SUV) has a Schrader valve located on the fuel injector rail to which you can attach a fuel pressure gauge. So, let’s say you attached a fuel pressure gauge, you’ll get one of two results:

What kind of engine does a 1988 Ford 350 have?
I have a 1988 Ford F-350 with an EFI 460 engine. It will start, run about 2 seconds, then dies. Will not re-start, seems to be flooding at this point. Wait a couple of hours, it will start, run a couple of seconds, die again. I have replaced the high pressure fuel pump, fuel pressure is at about 43 PSI key on, engine off.
How does the fuel pump work in a Ford 350?
If not, Ford use to have 2 fuel pump; One in the tank that send AMOUNT of fuel under low presure, and the other, (the one you replace), for high presure. If the primary is not sending suficient amount, the second will not stop asking for more, so you wil have a few seconds of propper fuel in the engine. Got it? No other idea for now. Good luck.
Why does my 88 F-350 have zero presure?
I was having such kind of problems with my f250 88, (An 5.8 Lts.), so if the new fuel pump do not stop, it may implied that the FUEL PRESURE REGULATOR is gone. All the fuel is passing to the tank again, you would have near zero presure now.
