Runs but shuts off

Good evening,

Yes, the question will be the fuel pressure. Plenty is not reading. It needs to be a specific pressure. Do you have that pressure?

Did you see if the spark dropped out? when the engine dies does the tachometer drop before it stalls?

It could also be the crank sensor as well.

The relay is incorporated into the CCRM on the left front fender. It is not a conventional relay but built into the module.

PURPOSE
The Constant Control Relay Module (CCRM) interfaces with the Powertrain Control Module (PCM) to provide control of the cooling fan and A/C clutch. The module includes the PCM power relay to provide power to the PCM.
These relays are contained in one housing, resulting in longer service life and reduced wiring requirements for operation.

CONSTRUCTION
The CCRM has one 24-pin connector. Relays contained in the housing are independent of one another.

OPERATION
The relays contained within the CCRM are interdependent and work with each other. The following describes the different relay functions within the CCRM:

EEC Power Relay
For any other circuit in the CCRM to operate, this circuit must be powered up. This prevents actuators from being turned on without the EEC system having control over them.

Fuel Pump Relay
The fuel pump relay circuit controls the fuel pump. The PCM provides the ground circuit for the primary side of the relay. The secondary side supplies Battery Voltage (B+) to the fuel pump itself.
