Hello JACUSTOMER, this can be caused by a number of different issues. I would start by checking the connections at the starter and making sure that the batter cable is in good shape. You really need to do an OHM test on it with a meter. If these items are fine then the problem may be a bad crank position sensor or a bad ignition switch.
the truck has a history of running great, then start missing for a minute with just about total lack of power. But the truck continues to run. Then it starts to run smoothly again. The issue of not running only started after a number of times when the motor has has repeated intermittent missing bouts. Putting a charger on the battery has appeared to give the battery a increase which has enabled it to start, after which it runs smoothly.
The bad crank, and ignition switch possibilities would not be an issue in the motor missing intermittently issue.
Okay, are we having a problem with the engine cranking and not starting right away or a no crank condition? Or are we more concerned with the misfire?
I thought that they might bee related. However, I went out to start the truck today and the battery was sufficiently low that it would not engage. Put charger on it for 2 hours and it spun over quidkly and ran. When it runs it runs very well, until it has it's missing spell. The misfore lasts aboujt 1 maybe 2 minutes and then you are off to the races again.
What made me think they were related is the manner in which the started engaged but would not turn over the motor. The starter engaged, with sufficient force or seemingly fast enough that it should have turned over. Yet for 3 times it stopped dead after initially engaging and the gauges on the dash would flip over as if they are receiving lots of amps. I stopped trying to start the motor in hopes that in the contition that the truck was acting I could determine what was wrong. Unfortunate the next time the battery would not turn the motor over, and now it runs just fine.. Until next time..
