F4I fuel pump not turning on

Fuel pump works if I bypass everything and put 12v on it directly. I checked relays, tip over sensor. The relay is good but I dont hear it clicking, The tip over sensor works as intended because I hear the relay click when i tilt the sensor. Any ideas?

You gotta follow electrical from where you are getting current to where you are not.

Its a pink wire running directly into the botom of the ignition... its a diode right cj? I have heard a little about this problem... could be your rectifier also

Re: F4I fuel pump not turning on

yea, theres a diode in the ignition that drops the voltage from 12~volts to 9, the computer wont allow the spark or pump to function with out it. the pink wire in the 4pin connector that comes out of the ignition
