I just stumbled up this thread as my wife's car is showing the same symptoms - cranks and doesn't start. I followed the instructions above and got the following:
Testing the coil of the c/opn relay on pins 4B-9 and 4E-5 with the ignition off got a resistance of 170ohms.
Checking across pins 4A-8 and 4B-11 with the ignition in the ON postion I found the voltage to be 0. If checking the same pins individually with the multimeter grounded on the chassis I found 12v at both pins.
I then shorted the 4A-8 and 4B-11 and when trying to start I could smell unburned fuel coming from the exhaust but it still wouldn't start.
Do you think I'm looking at a faulty ECM and do I read right that the relay is integral to is and cannot be replaced without replacing the ECM itself? If this is the case where would I find it to get a part number or can it be found from the VIN?
Many thanks for any help you can provide :-)
