Do P-Pumps Knock When Going Out
I have been having problems with fuel delivery on my truck. I haven't been able to figure out what it is, but tonight when I was in the driveway it died. When I started it it started to knock on the pump side. I couldn't tell if it was the p-pump or the lift pump.
After it was knocking it died after about 15 seconds of running. I primed the lift pump and it stoped knocking but it was still very hard to start.
1994 12 valve
any help before I take it in would be great
After it was knocking it died after about 15 seconds of running. I primed the lift pump and it stoped knocking but it was still very hard to start.

I have a 12 valve also and mine you will be on interstate and interstate only and it will loose power start with a peck on the injection pump and will try to die out having seem like air is in the line. It only does on interstate but idk if its supply or plunger sticking also throttle seems to lock while it is pecking
