Hello there my good chaps!!! I've got quite the puzzling issue where the WF won't fire up after having briefly disconnected/reconnected the battery.
Yesterday I got code P0174 and swapped in a used MAF from one of my donors as I'd been experiencing backfiring, poor drivability & reduced MPG since Wednesday. I took it for a test drive after replacing the MAF and felt that it ran better but continued to backfire every now and then. I figured to disconnect the battery(Negative then Positive) for a while to clear a Check Engine light and to reset the ECU to have it relearn the Air/Fuel ratios incase it was all jacked up due to the defective equipment.
I reconnected the battery(Positive then Negative) after about a half hour and to my dismay have not been able to get the car to fire up. The fuel pump primes up just fine and the engine cranks with no problem but fails to ignite. I'm baffled by this as the Mark was turning on without issue prior to disconnecting the battery and am at a loss as to how it wont ignite. I checked the Fuel Pump Shut-Off but it's pressed in and won't depress. Is that normal?
I've read about the Crank/Cam sensors possibly being the culprit but swapping them in with new units did nothing.
Any and all suggestions are appreciated.
Thanks!!
