Turning the key over I get no crank no start. Dash reads pwr str, service engine, coolant. I just charged the battery. I had multiple fuses not getting power at my ECM. Ran a hot wire and they got power. I'm still not getting anything. Please help.

Hello,

I would highly recommend not running a hot wire to your vehicle's ECM. There is a fused circuit that provides power to the ECM, and any power spike or deviation that would be protected by the fuse could fry your ECM's computer chip and ruin it. I have seen this happen before. In the diagrams down below I have included the wiring diagram for your vehicle's starting circuit as well as the location, layout, and callout for your vehicle's Under hood Fuse Box. We will be checking the starting electrical circuit, so you will need to have a Digital Multi-meter [DMM]. here is a link explaining how to use one, if needed, below:

Please go through these guides and check the Crank Fuse 46[30A] and the Run/Crank Fuse 38[30A] in the Under hood Fuse Box. Here is a link below explaining how to check fuses, if needed, as well, down below:

Please check the fuses and report back here. We can go from there, if needed.

Thanks,
Alex
