This car will not start. When I first began experiencing problems, the car would just quit running occasionally and after many attempts to start, would finally start and run a few minutes to maybe twenty minutes.
Here is what I know so far.
The injectors are not working. There is battery voltage at the BLK/WHT wires of each injector. Using a LED test light connected to battery positive, I'm getting no flash when touching the second wire of each injector while cranking the engine. I haven't tested continuity from the injectors to the computer yet, but that's unlikely to be the issue because each injector uses a different wire from the computer.
I disconnected each wiring harness from the computer, inspected it, and reseated it.
I cleaned and tested all grounds. Engine and multi-wire ground on back of intake.
The spark plugs are firing.
Fuel pressure is good.
I have no DTC's. The engine light is not on.
I suspect CKPS issue, MAP sensor, or ECM.
Thank you for any help. Mark H.
