Sounds like your Sentry Key Immobiliser Module may be at fault. That's a Main Dealer Problem. Try disconnecting the battery lead for a minute or 2 then reconnect. Red.

The door security has nothing to do with the jeep no starting. Check your electrical leads and also terminal leads that run to the battery. If you can, get your battery and your alternator tested to see if theyre any good. If your dash indicates the following while driving;" Transmission Overheat", then, with the engine running, check your transmission fluid level. If the transmission dipstick indaictes that the amount of fluid is low add maybe a quart to it. if you do this again and you find thats its doing the same thing, then there might be a couple of things wrong;

- 1. You may have a leak somewhere. Check your lines and check around the transmission pan. If you find a leak around the pan, than that means that you need a transmission filter kit. This includes a pan gasket and filter.

- 2. If you lift the hood and look over to the left (standing at the front of the car) and find the reserve tank to have a dark color liquid in there, open the top and see what color it is. If it smells and looks like Transmission fluid, then that means you have a busted radiatior. If you open the radiatior cap and look down into it and see the that the color of the fluid is a pepto bismal- looking color, then its deffinatley time for a radiator replacement and flushing of old fluid out of the system.

-3. Transmission is burning up gears and needs to be replaced. i dont know what jeep was thinking when they put a three speed transmission in a car of that size that idles high beacuse of the gears, when it should be a five speed that idles lower being thats a bigger size car.

-4. Check your fuel lines and your fuel filter.

-5. The sensor that sends a signal to the number one cylinder to fire may have gone bad and needs to be replaced.

It's most likely, looking for a security key, not a regular key. Security keys have a chip in them, to identify them as a valid key, not a screwdriver. It's a passive anti theft device. Available from the dealers.

Somehow, your security key becamed unrecognized by your security system. I don't exactly know the fix for this, but maybe the dealer can tell you what to do next.

Just replaced the fuel pump in my 03 Toyota Matrix, car still doesn't want to turn over. What else could be the problem?


Explain doesn't want to turn over ? If the engine cranks when key is turned to the start position . You have a cranks but won't start an run condition . When you say it won't turn over , we as automotive technicians think the engine won't do anything when the key is turned to the start position. We don't just replace parts with out doing testing on the electrical circuit for the fuel pump , an hook up a fuel pressure gauge to test fuel pressure . It has to have spark , fuel an compression for the engine to start an run . Also the anti-theft system can't have any problems . Is there a security light lit on the Dash ?

Electrical problems


Same thing is happening right now on a 2002 Monte Carlo. When the key is simply turned to ON, all of the lights on the dash starts blinking rapidly. When I attempt to turn the car over, there is no CLICK or anything from the engine - nada. Ignition turns and the dash goes dark, as if it wants to TRY to start - but nothing happens.
But, when I press the brake pedal (and the key is just sitting in the ON position), all of the blinking lights stops flashing and just stay lit. Therefore, I changed the brake switch, thinking it might make a huge difference. Didn't really help at all. When the key is turned, you can hear the fuel pump engage and everything seems to be ready to go. But, the car won't start (it will only start when it feels like it)...hit and miss, pretty much.
Does anyone know the TRUE solution to this issue? Does the ignition need to be replaced in order to get this car to crank over

I have the same problem on my T &C 1998, There is a lose solder connection in the behind the dash, instrument cluster. I found that pounding the dashboard once gets it going again. Hint, if you see the gear display ( P N D 1 2 ) lit up you are good to go. If you don't see it lit up with the ignition on, give the dash a god pounding with your fist, works for me every time. I actually had the van towed twice and as soon as it was at the dealer it cranked up. Good luck, MJ

you need to check all fuses one by one for loose contact.leave the igtion key to on position and try to tap the fuse box, shake wires from battery going to inside the car.A testlight is effective in diagnosting this trouble.Probing the wires on the ignition switch while turning on the key.Need somebody to observe the cluster while performing the troubleshooting.
