Hi

I have a periodic problem with my '93 saph Cos 4x4.
Sometimes the fuelpump doesn't run when I try to start the car. It happens something like 2 times during a week.
I have changed the pump, as I thought the old pump had let go.
then it was working for a while and then started to cut out again.
Then I checked the wiring and at last I checked the relays. I have changed two relays connected to the fuelpump and the problem still occurs about twice each week.
And it seems to get more and more often.
Could it be an ECU-problem? I'm running a Stage 1 chip.
I'm now running with an extra wire in the boot, so I can connect the pump to the bootlight, so it can get some power to start the car.
When the car has been running for some time (varies alot!), I can unplug the wire and the car runs as normal.

Please help!

Thanks!
