Error Code 42 Need help trouble shooting a code 42. This is an 88 TBI engine. While in park or in motion car will begin to stall and the check engine light comes on. Thanks |
42. Fault at electronic spark timing circuit OR Fault at direct ignition system OR Fault at fuel cutoff relay circuit |
42. Fault at electronic spark timing circuit OR Fault at direct ignition system OR Fault at fuel cutoff relay circuit good luck check your distributor they tend to go bad |

it shouldn't display the code for the icm, mine didn't, I actually am running code 42 right now because my timing is off just check your distribution components |
It would show a code 42 if you had a short to pin "D" of the ICM.:D |
yeah that i learned today, but if it isn't working properly it wont if he is starting and stalling.......... |
You'll also show a 42 if the EST connector is disconnected for you to set the base timing and you forget to plug it back in. :D Ask me how I know. |
Error Code 42 The code 42 is intermittent and I have already replaced the pickup coil and the ICM. The EST connector is connected. The car starts to stall, comes back to life and kicks on the SES light. I only find the 42 in the ECM and not sure how to start trouble shooting. I cannot reproduce the problem at will. |
ECM Swapped out my ECM and the issue seems to be resolved. |
