Stops running at a redlight have to reset alarm then it will start

Insert ignition key,turn forwards to run. Just till red lights & theft/alarm light goes on. Do not try to start or engage starter.Leave on till light stops flashing. It may take up to 10 minutes. Once light stops flashing turn key off. Then start car & let run for awhile.

you CANNOT bypass the alarm.but you can reset by locking/unlocking the boot with the key or use the drivers doorlock.to do a reset as per the book.

I had this same problem. I put in a can of engine restorer and lubricant, the 8 cyliner formula and had no more problem with that light coming on. this is found at advanced auto at about 10.00 a can. it will restore your engine's compression.

it is possible that the battery for your remote is dying,replace it and if needed, do a reset of the alarm/immobiliser.

start the car. if that dose not work remove ground form battery then after it stops put ground back on that will reset the alarm.

If ithe alarm is factory when they will have to reset the alarm module with a scanner. If the alarm if aftermarket go to the control module and see if it has a reset button. FOBs (remote) can reset alarm. You Jeep is always set for break-in mode. The FOB sets this when ever the FOB is used to lock the doors. May be bad alarm module - Sorry - Good luck

There is NO kill switch on the 2000 Elantra... HOWEVER, there is a thing called the Key Fob (keyless remote entry system). There is, however, a system in place called the 'starter kill' circuit and it is activated when the burglar alarm goes off.... it's called the burglar alarm relay and it is activated to prevent the engine starter system from being used. There are three ways to get the engine started in such a circumstance... 1. use the key fob to 'disarm' the system... 2. put the key in the ignition and turn it to the 'RUN" position and wait until the alarm stops (horn stops beeping and the parking lights stop flashing), then the engine will start.... 3. pull the starter relay from the UnderHood junction box and bypass the starter circuit (key in ignition and in the 'RUN' position), jumper the starter solenoid circuit to energize the solenoid to start cranking the engine -- it should start then.

Electric fan on radiator is goofing off. chk if it comes on at all but watching gauge and listening for fan start uo just above operating trmp. Fan helps cool under 35 mph. Forced air cools over 35 mph.

You need to disarm the alarm, the 2 problems are related, the start and stall is caused by the fuel pump interupt function of the factory alarm, you triggered it when you replaced the battery, The reset procedure is in the owners manual.
