Truck has been running fine now last 2 days. Intermmitent issues are always the most difficult. Anybody have any other ideas or input on the battery condition?

 

Truck not starting again now. Very clear the fuel pump is not kicking on. Double checked the 02 sensor relay and the fuel pump relay. All fine. I also hooked a jumper box up to the battery to make sure it wasn't a old battery low voltage issue. voltage was reading about 13.3.

I'm now going to contact autocomputerexchange where I bought a reubuilt pcm in 2010 and see what they think. Most likely probably buy a new one and return it if it doesn't fix the problem.

Another side note I didn't think could possibly be related until now is that my parking brake/abs lights have been coming on intermittently as well. I have researched that this is usually a bad rear ABS speed sensor. Could this sensor be related to my other issues? I just ordered one and will install that next week.

 

Wanted to follow up on this post with the solution. I installed a new Rebuilt ECM for the 2nd time now and the truck is running great. Hopefully this one will last longer than 40k

I guess I can justify installing the new fuel pump by calling it Preventative maintenance.

Thanks for help.
