Hey DARRELL47,

Let start with a scan but it sounds like the crankshaft angle sensor has failed does it have fuel pressure?

Here are a few guides that will help you get the problem fixed.

I have no spark at cylinder one ( it has individual coils for each cylinder ) so to trouble shoot the coil I plugged it into another coil plug that had spark and the coil worked. So I plugged it back into the number one cylinder and still no spark. So I checked power to the number one plug that plugs into coil and found power in one of the three wires but still no spark. All other coils get spark. Except for number one coil. No codes show up.?

Check fuel pressure and check compression and basic engine stuff like plugs wires etc. Then see if there is a vacuum leak like a line off etc. Spray choke cleaner around intake and throttle body.

Did all that. All wire plugs that plug into coil pack have power. Each spark plug has its own coil pack. But no matter which coil pack I plug into the no one cylinder wire harness has no spark. But if I plug that same coil pack into the other individual wire harness for the other cylinders it gets spark but I have power at all the plugs that clip in to the coil packs could it be a crank to cam timing issue

I don't think so, check your wiring as all the coils ae powered by the same wires and grounded the same except for two. Diagram at bottom of coil wiring. Might be a capacitor problem as well. Turbo motor in second pic
