CJM Fuel Hat and 340lph Pump ISSUE

phunk

These issues cannot be related to the billet top hat since it merely a replacement mount for the fuel pump module. Based on your DTCs, it sounds like there has been some incorrect wiring performed, or the vehicle was turned on with the connector disconnected at some point.

If the fuel pump is turning on as it should, but the car doesnt start/run correctly, assuming it originally did start/run correctly before installing the 340 pump, your problem is most likely the idle pressure fix was skipped when installing the pump... and its just too rich due to excessive pressure.

Section 9 covers what is almost definitely the source of your problem based on your descriptions so far.

Because the engine was flooded. When you disconnect the pump and then crank the engine, fuel pressure will drop and momentarily pass through an acceptable range to run the engine before it falls too low and the engine stalls.
