    4.3 MPI Not Starting - Starter solenoid click

    Here’s what I found. On my engine I don’t have a slave solenoid, but relays for the main power, fuel pump and starter. The starter relay was clicking when I turned the key. I swapped it with both the fuel pump and main power relay and all three clicked. I plugged the main power in as well as...
