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.
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.
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.

Are there any problems with the Ford 4.6 liter engine?
Many of the 4.6 liter Ford engines use plastic guides, which isn’t the best for reliability.

Why does my Ford 4.6 engine misfire so often?
Engine misfires aren’t really a problem. Rather, it’s usually a symptom of another underlying problem with the 4.6 Ford engine. One of the primary causes of misfires is the ignition system – spark plugs and ignition coils. It’s standard maintenance stuff, so it’s probably not fair to call it a true issue.
