Changing the key switch....
I have a 1989 F150 300 2WD
I have had some problems with fuel not getting to the engine. I have found the pumps are OK with plenty of pressure. I replaced both the EEC and FP relays but the only way that the pump will kick in is when I manually force the contacts together which allows the EEC to activate. If I keep the contact together I can fire the truck up and all seems fine until I release the contact.
My question is since nothing happens (gas) when I turn the switch unless I hold the contact does anyone think it could be the switch?
Thanks people,
Earl
