Hi guys I'm having an issue with my 96 grand cherokee limited edition V8.
Here is the information as i have it.
Issue: Turns over but will not start.
Facts: -The alarm is active (no sound but lights flash, I believe the fuse for the horn on the alarm was removed).
-A new key was purchased from the jeep dealer (turns in the ignition but not in the door locks)
-I live in Northern Ontario, so it is extremely cold this time of year.
-It has been parked for roughly 5 months
-It turns over and goes on briefly but dies off within a matter of seconds.
-Used gas line anti-freeze to no avail.
-Attempted to boost through another vehicle.
So basically my question is, could the alarm be allowing the engine to turn over but essentially stop it before it is able to run? If this is the case, my key fits into the door locks but won't turn (i don't know if it is cold related) so as of yet I can't disengage the alarm like that.
If it is not the alarm, what would cause a vehicle that retrospectively ran perfectly before to no longer turn over after sitting 5 months in the cold.
NOTE: Should we not find a solution by the weekend it will be towed to a heated garage at which point cold will no longer be a factor.
Please fill in your Jeep profile info...

Welcome to JF!
Disable alarm with remote fob.
If your keys worked before, then perhaps the dealer didn't cut the new one properly.
After sitting for 5 months, make sure battery is good.
Check for proper fuel pressure at the fuel rail.
The remote was lost with the original key, the new one turns in the ignition but not the door lock (driver passenger and hatch), if that makes sense? It turns over and runs for a short couple seconds (less then 5), would it be able to do that if the battery was gone? Will check the fuel pressure tomorrow when I go see it. Thank you.
