What to do if remote does not start the truck?

What makes you think you have Remote Start on your MYSTERY vehicle. It sounds like you don't.

On an OEM Installation, it comes with the vehicle and you get a special remote. On aftermarket remote starters you have a separate remote.

It may be the Security module. The "cold start" routine is necessary to make the engine run cold. When you are already inside the vehicle and turning the ignition switch it is not using the "wireless" feature of the FOB's. The ignition switch is hard wired to the vehicle module and would be sending the signal through a wired connection. For the warm start, the "cold start" sequence is not needed and all this proves is you have spark and fuel. Many engines are running too lean to start without the "cold start" sequence. Another remote possibility is a stuck temperature sensor is keeping the cold start off, but that does not explain the truck starting with a key.

you may go to shop ignore your prob

i have a viper alarm on my car with remote start. it has a setting where i can choose how long my car runs after it is started. you might check to see if yours has this setting as well. if not it could be a faulty remote

If you are sure that everything is connected properly, then the only explanation could the ground when running from the remote starter to the bypass. If you are using data to data(D2D), switch over to wire to wire. Test the ground when running connection from the remote starter (white) to the ground when running connection of the Xpresskit (blue). You could even go so far as to connect the ground when running of the bypass to constant ground for the test. You CANNOT leave this wire connected to chassis ground.
Also, that vehicle has a second ignition wire(white) that MUST BE power up for remote start. If not, it will trigger the check engine light.

Sounds as if your immobilizer bypass is malfunctioning. To test, remote start vehicle. Check vehicle cluster (gages). If the immobilizer bypass is the issue, there will be car/lock symbol flashing rapidly. To confirm, put the key in the ignition(do not turn), remote start the vehicle. It should start. If the vehicle starts, remove key, remote start again without key. If the vehicle does not start, have the immobilizer serviced. If the vehicle does not remote start with the key in the ignition, the issue may be with the remote starter's starter output.

Aftermarket remote start systems are notorious for starting concerns due to the fact THEY ARE BYPASSING YOUR THEFT DETERENT FROM THE FACTORY.Definately in the remote start system.Are you using the factory remotes to open the doors?

IF ENGINE CRANKS BUT NOT START -, sounds like a short in the tach wire, plug remote starter in and cut the tach wire to the engine for the remote starter. if the truck starts then you remote starter module is faulty.

IF ENGINE WON'T KRANK -, then there is a starter kill hooked in with it. if you bypass this you should be fine. just follow yellow wire from ignition switch till you find where it is cut. rejoin these two yellow wires and you should be good to go

if the signal lights blink when you try the remote start take your truck to advance and have them check for codes tell them you want a code check and if there are codes ask what they mean and have them cleared my 2007 silverado did that if the check engine light was on
