My truck would not start this morning and I had to catch a ride and leave it at the house. I won't be able to get to it this afternoon but here is whats going on:

I went to auto start (Viper alarm) this morning and well it did not start.......hmm odd. Get dressed and go out to my nice and cold truck. Turn the key forward and nothing!

Hmmm, battery? Nope shows 12v on the gauge and the lights are bright. Radio and AC works........ooookay. No lights left on, in park..........looks good............try again, nothing. Does not click, does not turn over.

It acts as though you turn the key forward but never enough to crank.........so you hear the fuel pump come on but thats it.

IDEAS:
Alarm is equiped with a starter kill so I'm going to disconnect the alarm first and see what happens. Is it possible anything froze up (cel)? 18 degrees last night.........sounds stupid but the truck is stuck.

Just because your battery shows 12volt does not mean it is good. Try having someone crank the truck while watching the voltage drop at the battery. I bet you will see 9 volts while the assistant is turning the key forward. I bet you need a new battery.

the batter is about 10 months old and over sized for my truck by about 1/3.........i was going by the gauge on the dash, nobody there to help me.

i did clean the + terminal as it was a little "rusted" looking, not corroded

I have also seen alot of people have trouble with aftermarket starting systems. I would check your fuses under the hood and inside the truck. Probably labeled ign, or eng cntrl.

It is also possible that you have a bad starter. You can check voltage drop across it to see if it is ok. Usually a bad starter will show more than a 3 or 4 volt drop if it is bad.

I went back and the dang thing cranked right up grrrr. I think it was a relay in the alarm not working due to the cold as they are known to do. I'll try early tomorrow and see what happens while its nice and cold.

who installed you alarm?? they probably used a bunch of T-taps and butt conectors, ao you have poor connections. Installing an auto start is tricky job, everything needs to be soldered

Starter motor i think its called, went on my 03 2500hd 6.0. Lights, guages, radio, everything worked, but it wouldn't crank.

Starter Solenoid sounds like the culprit in your case.

Again, I'm pretty sure Tthomas's problem is the after market start system. I don't install them for this reason.

My brother and I installed it...............issue was probably a relay getting stuck......which happens.

Everything is soldered and wrapped. If it happens again I'll replace the relay but this morning it stared up with no issue.

Sometimes the neutral safety switch can cause that to happen, but I doubt that is your issue.

I have run into this a couple of times. Once it was a loose battery cable, the other time I just shifted into neutral and it started right up.

What is your gas milage? Curious as I have a Isuzu with a 6.0 Chevy V-8 and been anywhere from 8.2 mpg up to a high of 10.5.... Curious what others with this engine have been getting

I just got 11.6.........all highway due to a distant job. Today I was towing around a 5,500 pound machine + trailer.........tomorrow a couple 10,000 pound loads..........I'll get about 7.5-8.5mpg with this tank.

It does not really matter if the trailer is loaded or empty........I get about 8mpg with it behing the truck. NO trailer....I'll get about 11 mpg.

4.10 rear, 54,000miles on the truck, automatic........ext cab, long bed, 4x4

8.1L would be nice but the 6.0L is no slouch and is a hell of an engine in these applications

I can get 8mpg all day with the 8.1L, It will tow anything.
