I've been prepping my front end and valance the last month for new paint. My buddy uptown called and said his PPG salesman was there and to run it up so we could get the exact shade of 8774 ordered. It hadn't ran for awhile so after I got uptown I let it idle for 20 minutes or so. After I figured it was charged up enough I walked over and shut it off. Twenty minutes later I get in to leave and it just turns over and over and over.
We didn't have time for any precision testing but here's what we were able to find out; There's pressure at the rail (shot up and hit the hood insulation). We pulled a plug and there's spark. What we did find that was not working was the injector(s). When we pulled an injector wire and put a tester bulb on it, it didn't light. So the three questions I'm mulling over is;
-Does the ECM power the injectors?
-If by coincidence the one injector wire we pulled was bad, would the car still run on the other 5?
-Why would a perfectly idling car not have injection after it was shut off?
No codes by the way, which is weird, because it was storing a 42 up until tonight... It did flash a 1-2 1-2 1-2 over and over which I think it means it's clear, but Would a fried ECM even flash a 1-2?
Thanks in advance.
Swapped ECM with one from a '90 supreme. Nothing...
Check the basics, car needs air, fuel, spark to run do you have all 3?
Code 42 seems to point to Electronic spark control, chances are its been trying to tell you something. If I were to guess I'd check for spark and replace the ignition control module if no spark.
