Having problems with your 1992 GMC Sierra ?
The truck will start when cold but after driving and then returning 30- 60 minutes later it won't start. Turns over fine and the problem is occurring about 30% of the time.
When this happens,you need to see if it is fuel related,or spark related,check the fuel pressure,and check for ignition spark.By just guessing,I would say the crank shaft sensor is failing.I hope this was some what helpful.
