What times the relay to start and then stop?
The ecu does. it grounds pin 86 of the fuel pump relay. You can duplicate the effect by pulling the 4 pin connector in the back driverside corner of the board and grounding pin 3 (drivers side front of the plug). Not likely though that is the problem.
The power routing is complex and includes the main power relay - swap it out if you have a spare. Also involved is the fuse on the board (the rear one if you have two). Does your heater blower work? It is on the same fuse. A voltmeter or test light is really helpful. If you have one check:
12V on the drivers side of the fuse. No? Fuse
Pull the fuel pump relay. 12V at pin 85? No? Main power relay or ignition
Pull the main power relay. 12V at pin 85? No? problem is likely in the cockpit. check fuse 8 then the ignition switch.
Just to remind you of the obvious. Pull the power to the coil when you have the ignition on for testing and the motor not running.
