2000 Isuzu Rodeo (just purchased), anti-theft alarm goes off periodically for no apparent reason. Was going to remove fuse, but it is already gone. How can this be possible, unless someone has bypassed the fuse box for this component? Nothing is readily apparent to my untrained eye.

Your alarm system should have a sensitivity setting screw, if you can locate it, it's probably buried behind your dash. If you adjust the sensitivity it might help with the problem.

Have you verified the timing belt isn't broken? It's getting fuel?
Have you recently purchased a new ignition key, or did the battery go dead on your fob? Could be fuel pump, or even a fuse.
Start the cheapest....Check all fuses, under the dash and the hood. Listen for the fuel pum to buzz when key is turned on.

post symptoms.
same car ?
what fails,
1: engine wont run immoblized
2: alarm dead.
3: alarm trips when all is good.
4: does car drive perfectly day and night.
5: do all other things work perfect. radio, lights?
6: do any cluster lamps fail, keyon, for example
the immobilizer lamp must go out, per operators guide.

we can not guess any of that.
it must be stated up front
why not start your own post.?
with all symptoms. good and bad.

well the only thing that states about a anti theft alarm, in my manual, is if you leave your key in the ignition, and open the door it will sound a buzzer, to remind you that you need to remove your key, this is on page #114, nothing else is mentioned about this sorry not much help.

Most cars that are mid 90s and newer had a remote feature. If you take it by the parts department of and Isuzu dealer they should be able to order you one or two.

A 98 Isuzu rodeo alternative alternative little key does that work the alarm system

This has to do with the Auto's Computer system and should ONLY be done by a Factory Rep who knows what he/she are doing. not a home mechanic chore!!

Could be your neutral safety switch, or it's not all the way in park. Broken or loose wires in the starting circuit. Inspect all wires and connectors at the battery, starter solenoid, and ignition switch. Or your starter pinion is jammed in the ring gear. Remove starter and inspect. Last but not least, your engine is seized. You don't want that one. Good luck.

I'm assuming its an original alarm or system that came from factory or dealer. When the light blinks is because the alarm is activated. Look underneath the radio the alarm brain might be there. There will be a label on it saying alarm or security system etc. Disconnect the harness to it and try operating your vehicle.

i put a new stereo in my 1998 isuzu trooper now the anti theft wont let car start what do i do
