95 dodge intrep. wtith error 12 55

if the timing belt was installed correctly and there were no bent valves
the next place to check mis the distributor
is the firing order correct or is it 180 degrees out

The first thing you do is run a test of the engine control computer through the OBD2 diagnostic port with a scan tool.

Please post once.

If the Eagle is 2 wheel drive try to determine if it has a 41te or 42te transmission. These can be interchanged by a knowledgeable mechanic assuming your vehicle is compatible. Many times these transmissions are referred to as a 604 or 606 respectively. The weak link in the 604 is it's output shaft splines.

Heather, new battery new starter. it sounds like the starter ring on the flywheel is worn. did anyone check the voltage output on the old battery. did anyone check the old starter? when you turn the ignition key is there any clicking sound from the starter?

Bad solenoid i would guess. Not making a connection there. Any basic wiring and ignition switch problems should be alleviated by jumping the starter with a screwdriver. I would check the solenoid and starter brushes

have your battery load tested at parts store

I HAVE A 98 INTREPID AND I WENT TO A JUNK YARD AND JUST PULLED THE PASSENGER SWITCH OUT OF THE DOOR AND UNHOOK.WIRES....VERY EASY....PUT IN YOUR CAR AND THAT SHOULD WORK...ITS PRYS OUT OR PULL OUT WITH PLYERS....THESE SWITCHES CONNECT LIKE A CIRCUIT AND IF PASSENGER DOOR SWITCH IS BAD IT WILL NOT WORK FROM DRIVERS OR PASSENGER SIDE...98 TO 2000 ARE ALL THE SAME PARTS....HOPE THIS HELPS.....

Have you checked the Automatic Shutdown Relay (ASD) under the hood?

Do all the warning lights in the instrument cluster come on when you turn the key? If Yes, then you need to check the neutral safety switch on the side the transmission[Automatic in your Montero?], as these are a known failure part for higher mile Monteros. You lose power to the starter solenoid as a result of the switch contacts going bad. Have someone put a test light on the solenoid wire at the starter motor, while you or a friend carefully tries to start the engine. If the circuit is working correctly, you'd see the test light turn on brightly. I'm betting you'll see no light, since I suspect the switch isn't letting power through.
