hey all, i'm stumped.

I have a 95 850 turbo that wont start. I drove it 2 1/2 hours with no problems at all. stopped at a walmart and wouldnt start 20 minutes later. Ive checked for spark, its there. New Plugs, wires. Checked for injector pulse with a noid light and it has pulse at the injectors. New fuel pump. the car has over 300K so i figured it was a good idea to replace that. New fuel filter also. there seems to be pressure at the rail also. why is this car not starting? I'm stumped. there aren't any fuel leaks between either. . . . . thoughts? I'm stranded 2 hours from home with this and its 10 degrees outside and am about out of options!
Thank you thank you thank you

    Hi, I You have fuel in rail it should start, if stalling in few seconds > 103 fpr.
    after few hour's drive no lawn mover syndrom but perhaps cam.pos.sensor?
    the second option is ignition-key-lock not giving power during crancking?
    very difficult to quess. the one and only stranded case was fpr with my 2x850-94s I got. good luck.

    I am sure you checked for trouble codes and found none. So, that means fuel delivery.

    Grab a paper clip and pull the fuel pump relay, short leads 15 and 87 with the paper clip. That should turn the fuel pump on while the key is on. Try to start again. The paper clip will get very hot rapidly, so be careful.

    The fuel pump relay is #103 under the fuses.

    You should also check the cam position sensor, the exhaust cam cover on the driver's side. Make sure the CPS wires go no where near the plug leads and are not cracked.
