Why does it take 4 or more tries to stsrt

Does it not crank... or crank and not start??

Avital is one brand of remote starter that features easy-to-use keyless remotes. These remotes can be programmed wirelessly to your engine and then added to your keychain. Once programmed, you will be able to use the remote from as far as a couple hundred feet away in your house, the street or a parking lot. If your remote is not working, you can troubleshoot the remote and get it resynced in seconds.

Enter your car, leave your driver's door open and insert your key into the ignition.

2 Turn the ignition to the "On" position and press and release the "Valet" button on your remote.

Press and hold the "Valet" switch again after releasing the first time and wait for the system's siren to chirp and the LED light to blink.

4 Continue holding the "Valet" button and then press the starter button on your remote.

5 Wait for another chirp and release both buttons to complete the process.

You can talk to a transmission shop, but generally the problem is a weak pump or valve body. Once the fluid warms up the problem goes away.

If it feels like the transmission or engine locks up, it could be something in the trans or the torque converter.
It could be something electrical but it should do it every time you shift it if it is.

This is usually the crank position sensor...some parts shops can help you with the location...hope this helps:) This should keep you from being stranded...

What about the fuel pump relay. I had a car that would stall and would take 5 minutes to restart and it wound up being the fuel pump relay.

when you say it won't start again until the next day? does that mean after turning your truck off it won't start immediately? After a couple of hours of sitting have you tried it again. Are you sure your truck is running fine? is there a sulfur smell or extra warm coming form the floor? It could be your catalytic converter which is clogged, when the truck is cold.. you are getting enough exhaust escaping allowing the truck to run, but it will be very restrictive and I highly doubt that you are getting good acceleration, once this is hot is so restricted that it will not allow the truck to restart.
This can be a serious condition and if parked over dry grass or trash could actually start a fire. Take you vehicle to a respectable exhaust specialist.

About the only thing within time that can change from sitting that would effect starting performance is the fuel. The fuel is probably evaporating from your lines and other areas of the system.
Try turning the key to start with a pause till you hear the fuel pump stop, THEN turn it to run.

you have a faulty injector

Remove plugs, clean and dry(warm) them and try again-common fault
