Keep getting code p1391

You may need a shop manual for this one.
Code 1391 means the crank sensor or cam sensor signal is not steady or dead at times.
The distributor acts as the cam sensor, so it could be that or the crank sensor, or a problem with the wiring harness.

Check camshaft and crankshaft sensors and wires leading to them. This code means it the computer isn't getting signal from one or both sensors.

What Is This Error Code P1391 Mean

I have done some research and found my shop manual for a Pacifica doesn't show a code P1391. I found it at another web site it's a crankshaft or cam sensor. What I found is if the car is running somewhat smooth replace the crank sensor if it is shaking when you accelerate there is a good chance your flexplate(flywheel) is cracked or broken.

Here are the meanings of these codes.
P1391 FORD - Glow Plug Circuit Low Input Bank #1
P1393 FORD - Glow Plug Circuit Low Input Bank #2
I think you most likely have a burnt out Glow pug controller. Whenever this controller is replaced all glow plugs should be tested for proper function.
