Well this could get complicated. But here is what I would do check all your fuses very carefully with a test light.
Check all fusible links.
Check your grounds under the hood. Their are several of them displaced around the firewall and the transmission bell housing.
If these are all good then you need to check for a 5 volt reference signal from the crank sensor. Before you do that if your car has a tachometer, check while you are cranking and see if that tach needle is moveing.
My guess it is not. Now you will need a schematic you will find in a service manual you need to check all the grounds comeing out of your computer. And then all the power wires comeing from your computer. If a ground is not grounded then you have a bad ground or a bad pcm.
I know this all seems complicated but obviously you are mechanical inclined or you would not have been able to complete the things you have changed. If this don, t help or you have more questions please feel free to reply. Ty BillyMac
