Hi, Ford Puma 1.7 Zetec, year 2000, 50, 000 miles, only recent change is the timing belt- could be significant. Used the car for a bit, then, one day it was idling, I turned on the air- con;, and it stumbled to a stop. Has not gone right or run since. If I start it (OK, and I can hear the fuel pump), it will turn foir a bit, especially if I am quick enough to run it a 2 - 3000 revs, but eventually it starts to die. Checked OBD, had a P0115 (Engine Coolant temperature problem). Changed the sensor, but still there and no improvement. I did tap the MAF once, and it seemed to cure it. Changed that, but the problem is still there. The fuel pump seems to go more often than I remember. So, wiring problem; fuelpump problem, timing or injection?
