Why not just replace "the computer"? It would make more sense (just kidding).

How did it test bad?
I should've had some voltage on cranking but I was getting zero. Additionally Resistance was zero. As far as the crankcase sensor, I had voltage, but resistance was lower than spec (20 ohm)

So what numbers did you get after replacing the sensors?

On crank fluctuations from 1.4 to 3 volts, 5 with key on. 200 ohms give or take 1 to 2.

Do you have a meter where you can measure the output of the sensor for frequency and amplitude? If so, Check to see if you are getting the same amplitude at the computer that you get from the sensor itself. If so, The wiring is good and If pin tension is good on the connectors than that circuit is fine.

I ran a check again, only code I'm getting is P0016.

Shoot, that's the timing chain. Do not crank the engine anymore.

Yes, change the timing chain and balance shaft chain. It is off by 1 or more teeth. You risk bent valves if you start it.

Excellent, I'll adjust timing tomorrow and report back here how it goes.

Adjust? You have to take it all apart to set the timing. At 150,000 miles, you need to put in a new timing set.

You should take it to someone that can fix it. You have no idea what you are in for.
