Depending on where you live, corrosion can be an issue on the PCB. Go over as much of the wiring as you can looking for issues. This will discharge everything is the system, and theoretically reset the security system. Insert key and attempt to start the vehicleĭisconnect both battery terminals and touch them together for 10 minutes (zip-tie). Removing key and attempt to lock/unlock doors using fob Leave key in on position for approximately 10-12 minutes until 'Security' Indicator disappears. Based on my research, performing the security reset procedure is affective 50% of the time. Even if the pump is priming the immobilizer will prevent ignition signals from reaching the PCB. Do you also hear the Fuel Pump priming? if not, do you see a red or yellow 'Security' Indicator anywhere on the dash? If so, your truck may be immobilized by the anti-theft security system. You said your dash lights are functioning at the key-on position, which is a good sign.If you guys have any advise or tips it would be greatly appreciated.Īssuming you've double checked all fuses for continuity, and you're confident that no pins or wires were harmed over the course of your blinker diagnosis, we'll start simple and go from there. 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. 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. 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. 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. 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. 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. The starter relay clicks when the key is turned. 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. After reconnecting everything I went to start it and found that all the interior lights/functions i.e. 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. 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 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. So I’m no expert but I can usually pinball my way around most jobs from a few YouTube videos and internet research.
