Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
Replace the CPS ( Crankshaft Position Sensor ) with a Bosch one,
if that doesn't resolve the issue, then next step is to borrow a fuel pressure gauge from Advance or Autozone and ensure you have 50-60 lbs of pressure at startup.
The test point is at the end of the fuel rail at the passenger side front of the engine.
Possible problems : fuel pump, fuel filter.
