First, thanks for the detailed description. It helps a lot. I realize your post is almost a week ago; I hope this reply helps in your diagnostics (on time). I was just brousing around and came upon your post.
The issue you most likely have is the cam sensor being out of synch with the crank. You'll need to find the correct angle to which the cam needs to be set in relation to the engine block and crankshaft being BTDC or ATDC for piston #1.
For detailed info on P1309, go to motorcraft. Com homepage. Near the top middle it says Technical Resources; then in new window that pops up, choose OBDII Theory and Operation. You're given a list of choices. Choose your "98 model year OBD System Operation.
You'll have a *. Pdf file.
Lucky for you, Page 6 of 60 specifically indicates your fault code under "High Data Rate System". Your cam vs crank signals are out of synch. Also, the PCM needs to see the engine temperature rise to normal operating temp before all monitors can run, so make sure your Coolant Temp Sensor is accurate and functional. (Not the temp indicator on the gauge, mind you. You need to investigate the other sensor which the PCM uses to measure engine temp. It usually has 2 wires going to it.)
If you need details on how to set the cam sensor, let me know.
If you are confident about your cam/crank synch, you'll likely need a new camshaft chain and tensioners. Any excess slack in the cam-chain will thow off the timing for synch.
