I have a 74 2.0L original FI and the fuel pump has been moved to the front trunk. I converted to the in and out style (75-76).
My fuel pump used to go on for 2 seconds to prime, then off until cranking or running. I know this is how it is supposed to work. Mine now is on constant with the key in aux position (before starting/cranking or running) What controls this? The computer? I also have only 7 volts to the pump and 9 volts at the fuse on the relay board that pump power goes through. Good 12+ volts at battery. Finally to the question: Does the computer control this 2 second prime? |
