I've been searching up and down the interwebs to try and find something that may be the cause to this car giving me problems on mornings when the temperature is under 50 degrees.
First off. The Car is a 1988 323 Sedan with the 1.6L SOHC engine. (was automatic, but has been swapped to 5spd, in case it matters)
This started in the past week when temps fell under 50 or so at night and basically in the morning the car turns over but won't start. Come back in the afternoon and the car starts just fine. I started by jumping the test pin and I get one flash. To me it seems like a "long" flash which would indicate a code of 10 which is for the Intake air temperature sensor. I have checked the resistance of the AFM and checked for continuity to in the harness to the ECM, and both test fine. I have even tried swapping in a spare AFM and ECM both with the same results. I also took into consideration that the flash may be a short flash which would make it code 1 for ignition pulse. The connector is fine. I checked the continuity between the (-) on the coil and the (1M) terminal on the ECM and that was good too. I've also swapped in 2 different coils (including a MSD Blaster SS) and the results are the same. The distributor, distributor cap and rotor, plugs, and plug wires have also been replaced within the past 6 months and all still look good. The battery is fairly new, and reads 12.65 volts in both the cold and warm weather. I haven't had a chance to test the amps of the battery, but since the engine still turns over at the same speed as normal it doesn't immediately seem like it would be the issue.
Has anyone had a similar experience or know of where I may turn next?
Thanks in advance!
