Intermittent Hot Start Issue!!
Hows it going guys. Truck has a issue where it cranks fine if cold. Go to start an hour later it doesnt want to start. Only happens once out of ten times. 2003 silverado 5.3. Rewind back to November of '18. Walked out of store, go to start my truck and it wouldnt start in park. Put it in neutral and started first time. It then continued to do this occasionally until a month later it did it again and wouldnt start at all. I replaced the neutral saftey switch that evening and it ran fine for a couple of days.
Then it did it again. When you turn the key it has lights, power to everything and what not, but in the start position no sound or crank. I figured since i had to play with the key to get it to crank it must be the ignition switch. Replaced that in the on my lunch break in a restaurant parking lot. Worked great a few days, went to get my oil changed and then it pulled it again in oil lube bay. Tomorrow I'm gonna pull the starter and bring it in for a bench test. Only issue is it only does it when hot and only occasionally. I'm wondering if maybe any of you have had a similar issue? Thanks in advance. Also, once i figure it out I'm gonna post results.

Yeah. So the starter on the nbs is an utter bitch to to get out. My truck has zero rust on it, i fought with it for close to 2 hours getting it out finally pulling the dipstick tube to get it out. Other then that i got it tested and it passed a few times in a row. Im going to buy a test light and the next time it acts up im starting to diagnose it then. If its passed the relay i know its the starter/solenoid, if not i know its between the ignition cylinder and the relay. Go figure i couldnt get it to act up today on my day off. Intermittent problems are the worst. Ive never had to deal with them, just seeing other on fourms have them. You cant diagnosis them until it acts up, and even if you fix it it kills your trust for the vehicles not knowing if its gonna rear its head. Im gonna put this on my youtube channel and document it so hopefully jt helps others when i fix it.

Yeah the only time it likes to happen is when i drive around for 15+ mins. Then it only happens every so often. Seems like the only time it likes to do it is on lunch at work. Then get stranded in a parking lot for 10-15 mins. Im a lead electrician usually running a crew but this last week ive had to be on site with the owner of the company with a big project and it happened twice last week on lunch. Im at the point of probably gonna just replace the starter just for the sake of it. Anyone been burned on remans before?God knows how many times that starter has been turned over in 200k miles. Also, thanks for your condolences
