Hey guys, I recently bought a used truck of 1 owner, only has 80,000 miles
So one day I went outside tried to start-it and no no click or anything, I thought it was my battery checked voltage and it’s above 12volts perfectly fine, I then go to dealer and purchase the ignition starter switch, replaced that and still nothing, I go to the starter relay pull it out and jump pin 30 and 87 I hear 1 click from the starter , went and bought a new starter, installed it today hop in the truck try to start it and nothing same issue still, went back to the starter relay and jumped pin 30
And 87 and it’s cranking so now I know the starter is working, I try my remote start it turns over once and stops, I checked all fuses at the fuse box in engine compartment and all good, swapped relays around still nothing, I’m really stumped now and hoping someone here can chime in and help me figure out this electrical issue, any help would be appreciated , thank you

 

My problem was slightly different than yours but maybe this will help. I have a 2009 V6 Silverado and last January I first had trouble with intermittent start. When the key was turned there was no crank, no click but dash lights and headlights were ok. This happened a couple of times but it would start after sitting a while. It gave no problem at all from early spring until this past October when the problem recurred but it would not start after sitting. My mechanic replaced the ignition switch and it started fine for 2 days and then the same problem. He then replaced the circuit board for the under hood fuse/relay board and it started fine for one day. He thought the ecm was bad so I ordered one from Amazon and had to take it to a different mechanic to have it programmed. When this person was disconnecting it he said he found some loose connections at the wires and he "tightened" them. He said he didn't think it needed the ecm since it was starting fine and showed no trouble code. That was 3 days ago and so far it has worked fine but I still hold my breath each time I start it. When I had the problem and the start relay was bypassed the engine would crank but not start.
