Getting Code 542 - Fuel Pump Circuit
Don't mean to double post, so I apologize, Im new and I posted this question in the classic trucks section here https://www.ford-trucks.com/forums/9...ll-issues.html but I figure this was the proper place to post.
Basically while cruising the truck would very briefly cut out, whithin a 30 trip it would only happen once. My KOEO test gave me a 211 - PIP erratic or missing (which explains the engine cutting out) and a 542 - Fuel pump open, bad ground or always on. Power / Fuel Pump circuit.
Ive replaced the relay, checked the main ground (rear frame of the trucks ground gets 12.6 volts. Checked the fuel roll-over switch, and tapped all the wiring to try to get the engine to cut off.
Any ideas would be helpful,
thanks, mike
