gt40 engine shut down

1997 gt40. Skiing and after a turn the engine surgd a little. Stopped and did a few other idle things then started back up.  It ran fine for about thirty seconds and then shut down entirely.Back at the d I checked and no power to the fuel pump. Ran a wire from batery to pump and it is good. I ordered and installed two new relays. Still nop power to the pump.  Checked voltaqge to the three solenoid switches and they are good.  Checked the ignition voltage and it is good goingto the pump.  disconected the kill switch and hooked wires together, no change.  ohmed out the wire from the relay to the pump and it is good.  I would really appreciate any ideas.Thanks!!

He said he changed the relays. It could be the ECM. No fuel pump power is a symptom of a bad ECM. They aren’t made anymore but myself and many others have had a lot is success creating ones cheaply with the instructions in the “Hope for GT40 ECM” thread over at Planet Nautique.

Also, interchange number for the Echlin relay that can be found on rock auto is: RY241 and is around $6

I might suspect the PIP signal to the computer from the distributor as a place to start troubleshooting

It's not a missing page.........the manual is no longer in the reference section.........temporarily
