Electrical Tech / Cranks but won't start--is the ECM bad?
The car was started one morning and ran fine for about 15 minutes, then it stalled. Now it cranks but won't start.
When the key is turned on, I hear a click and then the fuel pump starts running. I assume this means the relay is working and the ECM is getting power.
The check engine light should come on when the key is switched on. The check engine light does not come on now.
To check for spark, I connected a timing light. It did flash while the engine was being cranked.
I grounded STI to run the self-test and get codes. The self-test does not appear to run, and I am not seeing any codes. Normally, when STI is grounded and the key is switched on, the fuel pump should turn on briefly, then it should run the tests and give out any codes. Instead, the fuel pump stays on. It doesn't run the tests, and It doesn't give out any codes.
