Hi All...
This certainly is a frustrating situation!!! I am having basically the same problem and I too am lost! My 1987 s-10 2.8ltr V-6 starts and runs fine 'UNTIL' it warms up. As soon as it does it's all over but the cryin'.
When it runs long enough to hit that 'NORMAL' operating temp. the fuel shuts down and it will not start. I have had to have this sucker towed 3 times in 1 week.... (thank god for AAA).... When DEAD it still has spark.
It's like the thing thinks it's overheated but it's not 'HOT'. After it sits
awhile..... COLD.... it starts right back up and runs fine again 'UNTIL'...
Well... You know the scenario...
Here's what I have done (so far) to try to rectify the problem:
CHECKED:
1. Wiring and all plugs and connectors to fuel pump/tank etc.
2. All other plugs and connections under the hood
REPLACED:
1. OIL/FUEL SENSOR/SWITCH
2. FUEL PUMP
3. FUEL STRAINER
4. FUEL FILTER
JUST PRIOR REPLACED
not necessarily related)
1. ALTERNATOR
2. ALTERNATOR BRACKET
3. SERPANTINE BELT TENSIONER
4. SERPANTINE BELT
6 MONTHS PRIOR REPLACED:
1. BATTERY
2. BATTERY CABLES
3. WATER TEMP SENDING UNIT
(NOTE) When I replaced the temp sending unit my temp guage had pegged but the truck was not overheated. I replaced the sending
unit but the guage still pegged. Truck still ran fine though and later
I discovered that there was a direct short in the wire that goes to
the sensor. I repaired the short and all was fine again but at NO TIME
did the short affect the running of the truck. The reason that I mention all of this about the sensor is because I don't understand the fact that
if the sending unit/sensor is supposed to tell the ECM(?) to stop the
engine if it senses a problem then why didn't the short affect the
running of the truck?
Good luck to all of you AND ME on resolving this as I too am REAL
FRUSTRATED!!! Thanks for all of the info that everyone has posted.
