This 5th gen pickup (190k) has been in the family for 26 years and has been indestructible. The past couple years an issue arose.
Issue: The truck runs absolutely fine, but when its warm and you shut it off, it wont start, but its cranks fine. After sitting for 5-20 minutes, starts like nothing ever happened. Fires up cold perfectly every time.
Diagnostics: Pulling the coil wire from the ignitor to check for spark, there is NO SPARK.
Checking for fuel injector pulse with a node light, fuel injectors are NOT GETTING CURRENT.
So something is wrong that controls both. Again its cranking like normal. No check engine light.
Replaced: I've replaced a lot without any luck: ignitor, coil, distributor (crank sensor inside), MAF mass airflow sensor.
One more note: In the summer the truck also sometimes stalled, and when it shut off, you had to wait 5-20 minutes to start it again which almost caused an accident on the hwy. Not sure if this is related or not, but the stalling issue magically disappeared now (winter). Regardless, everything seems to be worse in the hot summer.
Please help, I used to live in this truck and drive across country, would love to confidently get back on the road!
