Hey All,
I'm dealing with some issues with a 1996 Ranger 4x4 4.0 auto tranny.
It has had a rough running engine.
Originally had a DPFE CEL code, so I replaced that. At the same time I also installed a new MAF and an IAC (they were the original parts, figured it was time to replace).
The new DPFE CEL cleared, but about 4 days later it threw a 'P0231- Fuel Pump Secondary Circuit Low' code, and started running rough.
I installed a new fuel pressure regulator, but rough running condition remained.
Had the truck tested at a Ford dealership, and they confirmed the fuel pressure was a little below specs, so I just installed a new Bosch fuel pump.
It is still running rough.
Fuel CB. and relay are new too.
Now it's throwing out a 'P0232- Fuel Pump Secondary Circuit High' code!
WTF?!?
Oh, and the Ford tech said that the ECM was bad, what are the options for replacing it?
Thanks for any help,
Robert S.
