1994 Dodge Dakota 6 cyl Two Wheel Drive Manual 78,000 miles
i installed an aftermarket fuel pump and fuel cell on my dodge dakota. I spiced the fuel pump power wire into the stock fuel pump power connector. I can start the truck fine but after about 10 minutes at idle the fuel pump starts making a whining noise and the truck just dies. I put a fuel pressure tester on the fuel bar and its reading over 100 psi and my truck only requires 45 psi. I bought a fuel pressure regulator and installed it inline after the fuel pump and it is not regulating at all. Also with the fuel pressure tester installed the pressure holds steady over 100 psi then about 10 minutes at idle the pressure starts to bleed off and the fuel pump starts to surge. I tested the volts on the fuel pump and it starts at about 11.3v then as the fuel pump squeals and the pressure drops the volts jumped to about 13v. I am lost and this problem is killing. I am looking for any input at this time.
have the same problem?
