ya i did that for a while and then i just got my alarm disconnected it runs a starter bypass so you cant start or steal the car... if you no the starter works and everything else was working before i would have to say it is a safe bet to just go get your factory alarm dissconnected it workes great now just tell them the alarm is stopping the car from starting and they will uninstall it for like 100 buck or so

im almost 100% sure it is your guys almarms... you can bypass it for now but i would hate to hear that someone stole your cars cause you ran a bypass like that

I ran 12 gauge wire from the top post of the battery to a push button switch I bought from Pep Boys (heavy gauge style) that I located just below the hood opening mechanism then back out and spliced directly into the wire that plugs into the starter on the bottom side. (it is easily pulled off the starter and I had plenty of room to work)
I just turn the key on and if the Bi### doest start, I just push the button and on my way.
It just did it this morning but not after getting gas or stopping for coffee. As I said, there is no pattern and I am an electrical engineer : )
Good luck !

so i'm guessing it was the negative terminal on the battery?

lmao im ghetto when my starter is crapping out i just hit it with a screwdriver for a couple minutes urn the key and im off =]
