Wally,
If the relay isn't stuck then T2 in the MAP sensor should be checked for a short. It's an NPN transistor that can fail shorted or open (mine failed open). It should have been a PNP which always fail open (run-on safety issue).

The relay has two separate coils. One is driven by the starter switch and the other by the AFM (MAP sensor box in your case). Start by unplugging the MAP sensor box and see if that stops the pump. ----- Original Message ----- From: [EMAIL PROTECTED] To: [email protected] Sent: Wednesday, August 20, 2008 5:15 AM Subject: Fuel pump prime - not stopping? 92 Link ECU car, when you key on normally the fuel pump runs for maybe 3-4 seconds, then stops until you start the car. Just before the rear/tranny munch-fst, the Sub started not stopping.. i.e. I key on and the fuel pump runs and runs and runs. What would cause this? I can't think of any electrical/sensor/programming changes that happened, so what are the triggers to tell it to stop priming? Wallyman p.s. the car runs, 47 days without it really sucked!! Replacement tranny is good to go (fairly smooth and quiet), 4.10 rear end with the torsen swapped in is silent... now to tackle the insanely long list of problems that need to be fixed, starting with the fuel pump issue. _____ _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
