Oskar this is what i got from the manual. Again this could just be a start since it is a broad error.
Test the fuel pump control unit.
-Disconnect fuel module
- with test light and ignition "On", probe connector "C" to ground Circuit it OK if light is ON. There is an open if light is " OFF.
- Probe Connector terminal "C" to "D" with test light. Circuit is OK if light is "ON". There is an open in the ground circuit if light is "OFF"
- Ignition "OFF", probel connector terminals "A"to "D" with test light. Ignition "ON" test light should illuminate for two seconds. There is an open in the circuit if the light is "OFF".
- Replace fuel module if there is no twenty second fuel pump operation.
See the attached image for the location of the module.
When the key is first turned ON, without the engine running the ECM will turn the fuel pump relay ON for two seconds. This builds up fuel pressure to normal operating pressure. If the engine is not started within two seconds, teh ECM will shut the fuel pump OFF and wait until ignition reference pulses are present. The ECM contiunues to power the fuel pump during engine operation. If the fuel pump relay fails, it is backed up by the oil pressure switch, witch continues to operate the fuel pump as long as oil pressure remains above 28 kPa.
So check your fuel pump relay. The location is on the attached image.
Good luck for now and let us know how it is going....
