Chrysler Repair: 95 sebring wont start code 42, obd ii scan tool, crank sensor

Question
QUESTION: the code 42 is from mil. my obd2 wont link with the cars computer and emmisions sticker does not read obd2 compliant it plugs in fine but wont connect. I orderd a new crank sensor already but still unsure. no spark and fuel pump comes on for 1 second when turn key... please help .   THANKS

ANSWER: Hi John,
The MIL 42 according to the manual is to do with the pcm not being able to close the ASD relay, or not being able to energize the fuel pump relay . But as you note, it does indeed close the fuel pump relay for that 1 second period of time as expected, so the 42 code doesn't apply to the fuel pump as being an issue. The ASD relay however doesn't have anything to do with the fuel pump on this vehicle, so it is possible that you have a bad ASD relay or a bad control wire circuit from the PCM to the ASD relay as the explanation for the no spark. You probably don't have a crank sensor problem therefor, but rather an ASD issue, if the 42 MIL code is valid.

history:
1995 sebring quit while driving --no spark and codes 12 & 42. bought obd 1&2 and cant find obd1 data link connector since the obd2 plug under the dash dont work apperently there is one under hood but cant find... think it is crank position sensor because fuel pump can be heard--- please help also have no spark ... THANKS in advance
 
Answer:  Hi John,
According to my '95 Sebring manual, there is an OBD-II plug under the dash by the steering column. There is no OBD-I plug anywhere in the vehicle.
The 42 code seems to pertain to the ASD relay's output to the PCM not being present/ignition coil primary circuit (depending upon whether you got the 42 code from the MIL light or the OBD-II scan tool. Which was it?). The crank sensor code is 11 via the MIL or 40 via the scan tool. So check it again both ways and let me know and we'll go from there.

QUESTION: where exactly is the asd relay and can bypass it

Answer
Hi John,
You will see 4 relays on the drive's side of the firewall, from the in-board to the out-board they are: fuel pump, ASD, transaxle, and back-up lamp. You can pull the relay and jump from the front pin socket to the rear pin which will get you 12V to the spark coil, the injectors, and the oxygen sensor heater. But don't leave it that way of course, for fear of running down the battery and also for safety in the event of a collision.
