The check engine light on my V8 EX just came on. I checked the codes and I'm getting:
P0191 Fuel Rail Pressure Sensor Circuit Range/Performance
P1237 Fuel Pump Secondary circuit fault
P1000 OBD-II Monitor Testing Incomplete
The light only comes on when the truck is started. I can clear the code when it's running and it won't come back until I shut it off and start up again. The truck runs fine without any other issues. I'm thinking the secondary circuit fault is causing the other 2 faults. What would cause this problem. Fuel pump seems fine, the truck runs fine!
Anyone else have this issue?
