Having problems with your 1986 Ford F150 SuperCab ?

86 F150 with 5.0. is not getting fuel

\015 I have checked the pumps and they are good. I tried to check relay, but not sure which one it really is. I bought a Chilton manual and they say to ground the service plug to get the pumps woriking and that does do the trick. However, it does not seem to tell us what may be the problem other than the PCM. If I disconect the jumper wire that kicks the pumps on, it dies. I pulled a relay on the firewall, It died. So I think I may have the right relay and it is good. I also believe the inertia switch is good since I can get it started. What else may it be?\015 Posted / edited by AnonymousUser on : 23-11-2020

Answers :

These are the relays located by the solenoid usually it is a connection problen in the connector check the red and brown wire even it wont look bad if you stick a test light in and you hear it click then you know you have a connection problem
Jump across inertia switch to be sure thats usuallyyhe first thing to go
