Taking out the remote starter might be a good place to start. Possibly there is an intermittent connection somewhere or the unit itself might be at fault.

 

I didn't know that the starter solenoid was outside the PCM. My fault for not pulling the manual, I figured everything went to the PCM first. In that case then I'd agree on ignition switch or remote interrupt.

 

I have an aftermarket remote start on my truck. I didn't install it and don't know much about it. I know that you are removing it, but would it start consistently with the remote?

 

It does the exact same thing. The lights blink like it gets the signal. Then it does nothing. It tries 2 more times and quits. This all started 5 months ago when I had a fail on the remote start try. That's why I'm going the route of removing it from the system. Don't know if it will make a difference, but it will eliminate that variable.

 

All the remote start does is mimic you turning the ignition key to start the engine. RS can do other things too like lock and unlock the doors, dome light supervision etc but those are not applicable here on this problem. If the RS can't start the truck then the problem is with the truck, not the RS. It still is a good idea to check the ignition switch wire harness and the switch itself. Those are your next most logical possible solutions.

Remote start can do more than just mimic you turning the key.

Some supervise the vehicle so that once it is running, if you open a door, then the key has to be inserted in so many seconds so or it shuts down. Most also have a timer so that it won't run forever.

But, no matter what, someone had to do something to the wiring. That could be bad. Not all installers are professionals in their work.

 

My remote start does a lot more than just mimic turning the key.
Push the button once and it activates the parking lights (the start button) and second time starts the vehicle. After 10 minutes it shuts down the vehicle and locks the doors if they were opened.
The doors can only be opened through the remote. If the doors are opened by the key while it is running after being remotely started it quits and can only be started by the key during the next 30 minutes.
Once the doors are opened via the remote and the vehicle remotely started you have to insert the key and turn it to the on position and put your foot on the brake before you can put it into gear or it will quit.
I didn't get a manual with the thing and had to figure all of this out myself.
As a matter of fact when I bought the truck I was standing inside the dealers office and messing with the key fob. I went out to get into my old truck and head home ( dealer was going to detail the truck). I drove by the truck on my way out and noticed it was running and the doors were locked. What??? So I stopped and used the key fob and that point realized it had the remote start. The dealer didn't even know it.lol

 

"RS can do other things too like lock and unlock the doors, dome light supervision etc but those are not applicable here on this problem."

I already said that a remote start can do more than just mimic OP starting the engine. I am aware of the functions and options on a remote start. I was only trying to say to OP that even if his remote start does do other things like run for only a specified length of time, shut down if you don't remote start with the parking brake on or put in the key within a specified length of time, roll windows up and down, interface with his smart phone and order him a pizza every Friday night, even if he has other options on his remote start the options are optional and do not apply to this engine no-start problem.

When you get right down to basics the remote start and ignition interface is what OP needs to check out. He also needs to check out the ignition switch itself and its wiring harness. Op has had the rs on the truck now for 8 years, most likely the installation is OK but that does not mean he could not have a loose or disconnected wire, a bad ground or a component of the rs that went bad.

I do not think the rs is causing this problem. If it were my truck I would check the ignition switch and harness next. Check the switch with a volt meter and test for continuity between the different poles. I believe the Haynes Book has directions for that test. Also check for the broken wire on the column with tilt steering problem. I don't have tilt steering so am not familiar with the problem first hand. You guys here with tilt can give info on that one. If the switch and harness check out OK then I would move on to the engine management sensors. OP's problem may very well be electrical but without codes it will be a process of elimination to find the solution. I believe the ignition switch, its wiring harness and related components are the next logical things to check.

The fact that the RS has access to all these systems can certainly cause a no start condition.
That is what I was getting at when I mentioned the other aspects of the RS system.
Obviously the RS was installed correctly and worked for a number of years and of course these systems will fail eventually.
Even as the RS ordered a Pizza for the OP it could have failed in the delivery of said Pizza and caused some type of chain reaction that resulted in a no start condition.
Sometimes Pizza is just what is needed to start.
As the OP stated everything worked fine until the "RS No start fail" at which point the problems started.
Of course it could be a loose wire, bad ground or failed system in the RS. But we all know how difficult electrical gremlins can be to find.

 

What and where is a remote interrupt? Also how hard is to replace the ignition switch? Is it on the column or in the key switch it self? THANKS EVERYONE!!!!
