1989 F150 5.0L

The problem is, I started the truck, and started driving. I noticed it seemed to be running a little rough at first. Before I went a mile, the truck just cut off, almost as if I'd turned the key off. The truck will turn over fine, but will not start. It seems that it's getting fuel, at least as far as the filter. I don't have a code reader handy, and when I tried to read the "Check Engine" light, I got code 22, 21 and 12, at least as far as I can tell. It's entirely possible I wasn't reading them right.

Edited because it seems that the 89 5.0L doesn't have a camshaft or crankshaft sensor.

 

had the same type thing happen on my old taurus. dam thing would just shut off with no warning. after lots of hunting turns out it was a bad engine ground the connection was corroded almost down to nothing.ive found when a crank or cam senser goes it wont start at all.

 

Keith, any ideas where I'd find the ground cable on the 5.0L in an F-150? I'll check that out before I start replacing those sensors.
