Chrysler Repair: 95: 3.3/3.5L LH no start, exhaust gas recirculation valve, side exhaust manifold


Question
i wrote in the other day about my car not wanting to start i did the ignition test where you turn your key over and the code it gave me is 1-2-5-5

Answer
Hi Brenda,
Unfortunately that indicates nothing has been noted of interest that would explain your problem. 12 just means that the battery power to the computer was disconnected some time in the past 50-100 ignition key cycles and 55 means "end of code readout". Unless you know of no disconnection of the battery in the recent past we have to look elsewhere.
So that leaves us to identify what else might be responsible for the problem and which isn't monitored by the computer.  
I would recommend that you take a look at the exhaust gas recirculation valve which is located behind the engine near the air intake throttle valve. The easiest way to find it is to look at the passenger side of the engine, specifically the exhaust manifold and notice a small solid pipe that braches off toward the rear of the engine. It is mounted in that pipe that runs between passenger side exhaust manifold and the air intake manifold. The valve is mounted horizontally and has a valve stem between its round vacuum actuator top and the body of the valve attached to the pipe, inside the flange that connects the two parts. The stem has a slot into which you can insert the tip of a flat-bladed screwdriver so as to lever the stem back and forth against spring-action which should move freely and close tightly. If the stem seems to be sticky so that stem doesn't close all the way by spring-action, then you can try spraying some penetrating solvent like WD-40 on the valve stem to freeup its motion, and then move the stem  back and forth with the screwdriver tip.
Then try and start the engine and see if that corrected the 'no start' problem.  
This part is not monitored closely by the computer, and if it were indeed to be stuck slightly ajar it causes very difficult starting and also die off of the engine when coming to a stop.
