No start no fuel 200

posted by  someone claiming to be hillbilly on  Thu Jan 16 02:57 CST 2003 [RELATED]

When you turn the ignition switch on, the fuel pump relay is powered up from the switch to terminal 15 (the blue/red wire...positive) on the fuel pump relay. At the same time, the ignition control module (right fender well) sends a short duration ground signal to the fuel pump relay and the negative side of the ignition coil. This negative causes the fuel relay to actuate and power the fuel pumps for about 3 seconds to pressurize the system. Upon cranking, the ignition module supplies a pulsed ground signal to the fuel pump relay causing the pump to run continuously. If you have power to the blue/red wire and the relay doesn't actuate, the fuel pump relay is the likely culprit. If the relay is not defective, then the problem is in the ignition control unit, ditributor or wiring between these components. The engine should crank with the fuel pump relay jumpered between terminals 30 and 87 (red wire and yellow/red wire). Also check fuses #7 and 13.
