Alan;
Here is a digifant cause and effect I noticed while trying to
trouble shoot a problem. FWIW the problem disappeared so I have not been
able to verify this.
Symptom: After about five minutes from cold start my truck would die.No
bucking or warning associated, just dead. Let it sit for ten minutes it
would start right up and be fine until next cold start cycle.
What I was trying to accomplish: After much T/Sing I was convinced the
Hall effect sensor was failing. I removed the distributor cap and
grounded the center coil wire (highly recommended for safety). I had a
voltmeter at the output and was watching when the hall unit should be
activated as I turned the crankshafts.
What I noticed: It appeared like every time the aperture rotor passed
through the Hall generator the fuel pump ran for a second and the
injectors fired. Check it out.
The problem never came back after this, it had occurred on the previous
ten consecutive drives. I must have seated a bad connection at the Hall
sensor when I was probing it.
Drive Safely & Good Luck
