Fuel pump issues while ditching my CNG
I'm having trouble with my 94 9c1. It used to have a CNG alternate fuel system that I got tired of hauling around and disassembled. Lately the car started stalling out suddenly while driving and in the process of trouble shooting it, I decided the octopus of a wiring harness had to go as well as all the left over CNG components as they only gave me extra variables to work with. Now that it is all gone, my fuel pump doesn't work. It doesn't prime and the car won't start. My service manual mentions a fuel pump test circuit but I'm not certain how to use it other than maybe shorting it with 12 volts, but I'm concerned that I might toast the circuit and compound my problems. Can anybody help me?
