So I'm looking for a little guidance on this. I've been driving along with no issues or warning signs of things crapping out. I had gotten a full tank of gas, drove for about 12 miles. Stopped the car. Started again. Drove another 12 miles. Stopped the car. Now it will crank over but not start.
For some context I have a new in-tank fuel pump. New fuel filter. New fuel pump relay. Tested the main relay and it's working. Tested the fuel pump by jumping between fuse 4-6 and that was okay. Checked all fuses and they're okay. Tried starting with the MAF unplugged and that didn't change anything. I also cleaned the grounds on the intake manifold. I also noticed that the OBD wasn't giving me any codes. No 1-1-1 from either terminal. It just lights up for as long as I have the button pressed down. This led me to wonder if it's a problem with the ECU.
THEN I tested the ECU according to the Bentley service manual and boom. The only test to fail is the first one. ECU power supply from ignition switch. (Every other test was fine.)
So I'm a little unsure where to go from here. Can I assume that this is a problem with the ignition switch its self? Or is it probably just a break in the wire at some point?
Any advice would be greatly appreciated!
