After I had an accident short-cutting the instrument panel I cant get the car running.
The car starts, the engine runs for a few seconds and then stalls. And I can do this over and over again....
Jumping the relay solves this problem, but I'll probably get some new ones driving without the FPR working.
I've already replaced the fuel pump relay, and that didnt help much...

Does someone know where to search for this problem?
-Seems like I need to know what's controlling the relay....

I'll be very happy for any help!

Thank you very much, but a little to "engineer-like" to me...
Couldn't fine any fuse to change, so I probably will try to change the whole instrument panel instead, and see if the problem lies there....

Could that be a solution..?

Or might the OVP cause this?

12 volts going to the FPR is hot at all times. Pull the FPR and check contact 30 for 12 volts. If the supply voltage is there, then you might have a ground problem, either coming from the ignition switch, or from the OVP relay.

Now I've replaced both the relays without solving the problem.

I've jumped the FPR and the car runs without problems.
It's a little difficult to check the relay bases, but both the 30 on the FPR and the 15 on the OVPR are hot.

Sombody got any idea how to get it working?
