Make sure the transmission gear selector is in the Park position, before attempting to start your Jimmy.
I don't believe the problem lies with in your security system.
Make sure the negative and positive cables are firmly attached to your Jimmy's battery, and also the contact's on the starter motor's solenoid, which you should be able to see by lifting up the splash shield on the passenger side, front of your Jimmy.
If none of the solutions above don't work then the problem is probably due to the battery in your Jimmy not having a very high charge level.

Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

SOURCE: can't remove key from ignition 2001 gmc jimmy

I dont know how much help this will be, but I'll offer it and let you be the judge.

Ive had this issue before in a different GM vehicle, a Pontiac Grand Prix. The issue turned out to be that the voltage from the battery was low due to corroded terminals. Once that was cleaned up and the voltage restored to normal, the key came out. Come to find out that this was a common issue in that vehicle, voltage goes low, you cant remove the key.

Now, on my vehicle and since yours is a GM product as well I will assume it will hold true for your vehicle too, there is a small hole on the bottom side of the column right in the area of where the ignition key cylinder is. If you have this, you can take a small tool like an allen wrench and push it up in there and that will press on a release mechanism that should allow you to turn the key back to its release position and pull the key out.

Hope this helps.

SOURCE: 2001 gmc jimmy not starting

Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

2001 jimmy loaded xrt egnition some times wont start lights go out on dash but nothing later 10min or so it starts


It sounds like the immobilizer is being set off. The factory reset time when it gets set off is 10 min. There is a wire that connects to the sides of the key where the "chip" is. Those wires eventually break or get loose just from time so its not uncommon. To fix it you'll need either a new ignition cylinder and key set that needs programed at the dealer or a non security key cylinder and key set and install a security bypass module that they have to use when you install an aftermarket stereo.

2001 GMC Jimmy with a 4.3L V6 auto trans. Will not turn over


The starter relay may have a bad connection, this is where your battery connects, and a power wire runs to the starter, also these have a ignition wire which is approx 14-16 gauge wire. The relay could be cracked or the contacts inside are going bad. But the other is the neutral safety switch that you mention. I would check these first.

Security will not let Jimmy start


You might have to let the truck sit for a few hours in the anti-theft system has been triggered. Also, try unlocking the drivers door with the key. There may be a switch in the door lock.

Turn ignition key and engine cranks but wont start. Does the security system need to be bypassed or maybe it's a problem with the coded key. Any suggestions?


the security light should be on if its causing the problem,do you hear the fuel pump when you go to start it,should hear a hum for a couple of seconds,does the key have a small plus sighn on it ?

How do i bypass security on 98 gmc jimmy 4.3


I experienced this problem, intermittant failure to start. This procedure must be done with the truck RUNNING.

Remove the cover off of your ignition switch. On the top there is a small wire connector that, once the truck is running, should be disconnected. This will turn on the 'SECURITY' light. All will be better, except the security light will be on at all times, much cheaper than replacing the ignition switch, however.

Wont start in rain


Jimmy fx:

Since it is moisture related I would suspect the ignition system. My F150 pickup started running poorly and on a hunch I replace the plug wires, the distributor cap and plugs. It made all the difference in the world

Good luck Loringh
