Fuel Pump relay/PCM issues (Page 1/1) thesolution33 AUG 09, 06:15 PM I have a 84 with the 3800 swap done, was running fine, untill I went to start it today and fuel pump was not kicking on at all. swapped out the relay with no luck, started digging. I have the "a" terminal of the relay going to the Pin 3 of the PCM as per the diagrams but when i pin it it shows only 10.2V going to the relay, both at the relay and at the PCM connector. Nothing should have changed between the last time i fired it up, so kinda stumped. Car turns over fine, and if i jump the pins it will fire up and run fine as well. Help?
