    i recently had a rodent get in through shifter boot and now truck won’t start. Turns over good and has fuel pressure of 28 at test port. Check engine light comes on when key is on which I was told indicates power to ecm. New batteries. Had to repair 2 cut wires found, but must be missing one somewhere. Ideas?

    Has the truck been setting? If the shifter boot is in that poor of condition, mayby its a problem that can't be properly diagnosed, without a trip to the shop. Rodents usually chew whatever at random. But the chewed up shifter boot is a new one on me. Good luck. Any code thrown up, start there.

    It sat a couple of weeks and rat chewed a hole in boot then. What i need to know is how to determine if i for sure have power to ecu and what might stop truck from starting after i do have power there. I'm thinking of crank sensor or low coolant sensor.

    Usually a bad low coolant sensor ( or if low on coolant) it would start then shut down. No power to ecm= no engine lights. Timing sensors good place as any to start. What about Clutch safety switch, wiring chewed up? Need to find the other wires that got chewed up. Good Luck.

    the rat might still be in the truck ..... waiting. .... just something to think about when you get it running and trying to get to sleep. .......... sounds like it's the clutch safety wife to me

    The engine will crank, if it was clutch safety it wouldn't crank would it?
