cranks no spark to coil

I have a 1997 Eagle Talon esi with a 420A motor. I'm getting no volage or spark to the coil. I have checked for fuel that seems good. I do have low voltage at the crank and cam sensor only 5.8 instead of 9v to each. does any one have any suggestion on where to go from here. No codes present

Hi welcome to AF.

We have a lot of 420 guys. Im a 4g63 guy so I don't know alot about specifics but, I would say start at the coil pack and start eliminating possibilities.

Are you sure you aren't getting spark (easy to test). If so just need to figure out why. Could be a few things causing it so start with the most likely and we will work our way back.

Here are the first steps I would start with. Check voltage at the middle pin on the coil pack. Remember there will only be voltage here when the engine is turning. So you have to be trying to crank it when you test for the voltage. Also do you hear the fuel pump prime when you turn the keys on? I would also unplug the fuel injectors and make sure they are getting power. This should get you started. To be honest I am not sure what the voltage is suppose to be at the crank and cam position sensors. Are you sure that its suppose to be 9v and not 5v? I might go put a meter on mine just to check it out.

If everything has power but the coil I would look into wiring issues. If nothing has power than the ECU is responsible for not giving power to everything and it is sensing a problem.
