I have 1994 chrysler concorde was getting off ramp and car stall would not crank check and is not firing plugs what cause this

May be a small vacumn line...trace all the lines to/from your intake manifold...Hope this helps.

Check that the wiring harness to the coils is getting 12v, this will confirm if the pcm is sending a signal for the sparks to fire. Check the ignition coil is sending spark to the plugs with a spark plug tester.

NO POWER TO FUEL PUMP......CHECK ALL IN LINE WIRING
NOT FIRING... START WITH COIL PACK, DIST CAP ETC...PLUGS/WIRES??????
"HOT WIRE" (DIRECT W/ FUSED JUMPER) TO FUEL .PUMP....NO - GO,,,BAD PUMP

How long since a tune-up? Check fuel--spark when problem is ongoing.
I always check for codes even if the lite isn't on. Of course if the mil doesn't work that presents a problem. The procedure below for using the mil to check codes.

Have you checked for spark? It might have a bad crank sensor.

Check the fuel filter on car for a restriction. Check the air filter for a restriction(dirty). also check the IAC valve (idle/air/control) located on the side of the throttle body. To check the iac valve, start the engine and disconnect the electrical plug from the iac. Listen for a change in the idle of the engine. then reconnect the plug to the iac valve and turn on the a/c and listen for the engine idle speed to change. If not then replace the iac valve. Hope this will help you.

need to read codes no free code from auto / shops

check for a bad eec relay in your buss box, probably under the hood.

I CHANGE CAM AND CRANK SENSOR,FUEL PUMP,COMPUTER BRAIN BOX AND COIL PACK STILL GETTING NO FIRE UNLESS I JUMP A FIRE WIRE FROM BATTERY

What you are reading is a 1-2 (12) and a 5-5 (55). The 5-5 is always at the end of the code string. The 1-2 (12) indicates that the battery was disconnected and the ECU (computer) has been reset.
