Okay, one thing to be careful about, if the engine stopped cranking, do not try to force it, if the wiring for the fuel injectors was wired up incorrect and there are fuel injector(s) staying on they can hydro-lock the cylinders with fuel, That can break connecting rods, pistons, and serious internal damage. It's better to take the time and get the correct wires to the correct ECM pins that they need to be at. The flashing check engine light means you have cylinder misfires that are bad enough to damage the Catalytic Converter. So, let's take the time and get every right before you try to start the engine again. At this point I would recommend you take the spark plugs out of all the cylinders. Unplug the ignition coils and injectors and crank the engine over to get any fuel out of the cylinders that might be in there. Just put some paper towel over the spark plug holes, because if they are filled with gas, it's going to come out all over the place.
I can imagine what you are dealing with, I've seen it before. Rodents chew the wires because they like the taste of the chemical in the wire insulation. They will chew the whole thing if given enough time.
So, let's Ohm out each wire to the ECM connector so they are all going to the correct control pins.
Will go step by step, Starting with the front ignition coils. But clear out the cylinders, and make sure the engine will still turn over. It will crank over fast without any spark plugs in it because there won't be any compression, so expect that. Also remember that with that fuel being sprayed into the cylinders and it not starting, it's going to wash the cylinder walls and cause low compression until fresh oil is able to get back up where it needs to be. Something to keep in mind if you want to run any compression tests. You will need to change the oil after all this as well, it will be contaminated with fuel heavily by now.
I'll go through the wiring diagrams and find the ECM connector pinouts that we'll need. So besides clearing out the cylinders, try not to crank the engine over much anymore until we get things straightened out.
If you're getting codes for other components, we will deal with them after we get the coils and injectors fixed up. You can post the code numbers here if you want, I'll look up the definitions myself.
