Chrysler Repair: 93 concord 3.5 won t catch and run, coolant temp, engine coolant

Question
QUESTION: My Concord will not start its just cranking over i hear the fuel pump going on but nothing it happen once before but then just started the next day?

ANSWER: Hi Joe,
Do a readout of the engine controller for fault codes. Use the ignition key:"on-off-on-off-on and leave on" doing that in an elapsed time of 5 seconds or less. The check engine light remains 'on' but will then begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then repeat the whole thing to be sure you have an assurate count of the flash numbers. Then group them in pairs in the order of appearance to form the two-digit fault code numbers.

for a translation.
Let me know what you find and we'll go from there.

QUESTION: codes 12 22 32 33 also the timing belt and water pump was just replaced on it but the not starting has happen once before that

Answer
Hi Joe,
The 12 and 33 are unrelated to a no start. 12 says the battery was disconnected sometime in the recent past, and 33 say there is an issue with A/C compressor clutch circuit.
The 22 could be involved in a no start. It says the the engine coolant temp sensor reading is off-value. Check the sensor's resistance across the pins. It should be 10,000-14,000 ohms when cold, and drop gradually to 700-1000 when the engine warms up fully. It is located next to the thermostat housing on the top front of the engine and has black/light blue and tan/black wires.
The 32 says that the egr valve is not responding to a test. It very well could be that it is sticking in its action. You will find it in the pipe that connects the right exhaust manifold to the intake/throttle body area. It has a round body bolted into that pipe, and round vacuum operator on the top and a flange area in between those parts. Inside the flange is a rod that has a circumferential slot. That is the egr valve stem. Use the tip of a screwdriver inserted in the slot to move the stem back and forth against spring action in one direction. The spring should fully seat the stem (close the valve). If it is sticking, then spray some WD-40 on the stem where it enter the body of the valve and work the stem some more to loosen up the action. The engine will not start unless that valve is fully seated (closed).
Then try to start the engine.
