Re: Crank No Start

As you have probably learned from research, the CPFI fuel system is very sensitive to fuel pressure. The specification is for a minimum 61 PSIG. I've seen them start at 58 pounds, and on occasion run at 54 pounds (as a record low running pressure).

If there is reasonable spark at the end of the plug wires, the next thing to check is the spark plugs themselves. I've seen a LOT of plugs still running the engine with over 0.090" gaps, and the some with side electrodes nearly eroded away to the rim.
