So I’m no expert but I can usually pinball my way around most jobs from a few YouTube videos and internet research. So the other day I set out to figure out why I was not getting voltage for the right trailer turn signal at the receptacle on the bumper. This was just supposed to be an easy job but I made some mistakes and could have swore I checked all the fuses, but of course it just ended up being a blown fused the end.
So anyway after pulling the top of the fuse box off and finding the actual wire for the turn signal and following its pins directly to the blown fuse I went to put it all back together. After reconnecting everything I went to start it and found that all the interior lights/functions i.e. radio, AC ext.. came on, but when you turned the key further to crank it, nothing would happen, mind you the truck had been running fine the day before.
So this is where I’m at right now. The starter relay clicks when the key is turned. Also to rule out the relay I swapped it out with the other 4 of the same kind of relay in the fuse box and it didn’t make a difference. I also know the starter is good because I made a jumper cable out of a small length of wire to bypass the starter relay. When I did that the starter spun and turned the engine over just fine, but it would not fire even when the key was turned.
To me I have to assume that somehow I dampened or provoked something to fail while I was messing around with the other issue, and making/breaking all those electrical connections, but I’ve triple checked everything, and can’t find anything visually out of order. To me it’s seems like it has to be some kind of electrical ignition issue since I know everything is working, and I’ve even bypassed it to turn over, but it still won’t start.
Like I said before I’m no expert on this, but I used to work on fighter jets in the Air Force, so I’m pretty mechanically inclined, and for the most part I know electrical repair, but when it comes to vehicles I’m just not that knowledgeable about them. If you guys have any advise or tips it would be greatly appreciated.
