Just wondering. I have Bosch FI at Colorado altitude. My car will not start up right away unless I turn the key and wait about 10 seconds for the fuel pump to prime. All plugs and wires new, new fuel pump, and fuel filter. Moroso electronic conversion. New battery. I try to drive the car once a week. Just looking for advice. Car is a 1976 2.0 with 1973 2.0 engine. OEM fuel injection.

Get a pressure gauge and install it on the rail before the fuel pressure regulator and check the pressure after turning the key on only once.
My car is converted to a 2-port pump but the pump only runs for 2 seconds and achieves my set 3 bar pressure easily. (EFI not Djet) |
