98 GT losing fuel pressure...
Hi. My 98 gt w/4.6 litre shows 30 - 32psi fuel pressure at start and within 30 seconds to 1 minute the pressure drops and it stalls. This happens at idle and on deceleration while driving. It has a new fuel filter, air filter and IAC. I'm not sure if its the pump, regulator or a signal problem from the PCM. Any ideas out there?

Look for a leak possibly somewhere.

Re: 98 GT losing fuel pressure...
Now I think it's the Constant Control Relay Module causing the problem. I hot wired the pump from the battery and the car runs fine. Does anyone have experience testing a CCRM for faults? It's $175 that I don't want to shell out unless I'm sure it's the problem.
