January 31, 2011I`ve been having issues with my wife`s 99 F150 w/4.2 starting. It seams after it gets hot or sets in the sun for a few hours it will not start. When you turn the key nothing happens, all the lights and gauges work but the engine will not spin. This is very random sometimes it starts sometimes it doesn`t. It has a new battery and starter but the issue is still happening. The truck has a Viper remote start system and I`m beginning to believe that might be the problem. This system has always had issues starting after setting in the sun, it would spin the engine but would not fire. Any thoughts?

February 1, 2011have you tried another key ?
sometimes with the PATS system the chip in the key goes bad causing a no start situation. just a guess.
February 1, 2011does the viper alarm have a valet setting?
have you tried putting it in valet at night and let it sit till the sun has been on it and then try starting it in the valet mode?
I don`t like the viper alarms
February 1, 2011gearjammer98, I thought of that too & yes I tried both my key and my wife`s....still does the same thing.
lounge lizard, actually the time it wouldn`t start for me I kept flipping the valet switch back and forth and that`s how I got it to start. That`s the reason I was thinking the Viper system may be the problem.
Thanks for your input guys!
February 1, 2011Buzz, if you look next to the battery, you will see a plastic box on the firewall. Behind this box is the starter solenoid. What I want you to do is to drive the truck around to get the motor nice and hot. Turn the truck off and get it to fail on you. Once you meet this, connect a multimeter across the 2 big terminals on the starter solenoid. Attempt to start the truck again. Did the multimeter stay up at 12.5 VDC, drop to under 1.0 VDC or go to somewhere in between.
If the multimeter jumped to something between 1.0 and 12.5 VDC, then your starter solenoid is bad. Replace. If the multimeter dropped to under 1.0 VDC, you have either a bad starter or a bad cable between the starter solenoid and the starter. If the multimeter stayed up at 12.5 VDC, remove the small wire connect to the side of the starter solenoid. Temporarily connect a short piece of wire between the large post on the starter solenoid that has battery power on it and the small post on the side of the starter solenoid. Did the engine turn over? If yes, you have a wiring issue inside the dash. If no, then your starter solenoid is dead. Replace the solenoid.

February 1, 2011Thanks Thermo, I was hoping you would see this post. I will try what you suggest but it may be a few days before I can try this as we had an ice storm this morning.
February 11, 2011Update: I`ve replaced the starter solenoid a few days ago and have had no problems at all. Time will tell if this fixed the problem, it looks like it has as you couldn`t go one day without having the no start issue....I`ll update this post again after more driving time.
February 23, 2011Update: Still no starting issues at all, so I`m saying this has been solved!
Thanks for your input Thermo....your the man!
