starting trouble/ electrical or ignition?
I have a 94 Toyota 3.0 v6. Truck will start and run for a second then
It looses fuel pressure and dies right after. After doing this 2 or 3 times
The truck will crank and run perfectly. But if you turn it off. Repeat the
Process. Is it something with the ignition killing the fuel pump?
Or something else. Replaced fuel pump still same problem.
Please help

"Starts and runs for a few seconds" is the classic sign of a problem in the VAF-COR circuit. Very easy to diagnose: jumper FP to B+ in the diagnostic connector. With key-on, the fuel pump will run. If that corrects the symptom, you have a problem in the VAF or COR.
Don't drive around with the jumper in. If a collision breaks a fuel line, the pump will continue running, spraying you with gasoline as you struggle to get out. Sound like something you want to happen?
