[QUOTE="CCS_56_EX, post: 14480945, member: 124071"] My cobra worked one day, then wouldn’t start the next. With key on, I have 0 fuel pressure - confirmed with both gauges and there was absolutely no pressure when I pressed the schrader valve on the rails. I’ve replaced both the FRPS and FPDM, and those didn’t do anything. When I turn the key on, I can hear the fuel pump whining for a couple seconds. I see 5 volts on the outer pins of the FRPS harness. The FPDM seems to get an inconsistent 12v from the green/yellow wire. My fuel system is completely stock, battery is 8 months old & shows 12v key on, and my fuel filter is 3 yrs 8k miles old. For DTC codes, I’m getting p1235 consistently, and p0190 sometimes. Any ideas on whats going on? [/QUOTE]
