98 Chev P0216 and P1214 looming troubles?

[dtreid]

98 Chev K2500, 200000kms, transplanted engine from 94.
Truck has been running great. Last night it would run for a few seconds and stall.
Started it this morning no problem. Truck runs great, but now throws P0216 and P1214.
I'm assuming that the no start has something to do with the new codes.
Switched PMD with another truck and didn't make any difference. Codes come back after a few seconds.

Is my pump on the way out or what?

My 2000 throws a p0216 once in a blue moon in the dead of winter if i didn't plug it in but I clear it and it doesn't come back. IN your case...not good.

The weird thing is that the truck runs great.

Check the Timing Stepper Motor. Make sure nothing is causing it to hang up.

What's the best way to check it? What should I look for?

grounds clean ???

I can recheck them, but the truck only has about 10000kms since we swapped the motor in and they were all clean then.

Cleaned the grounds (that looked really clean!) and the problem went away.

You put a 94 engine in a 98 ? Which IP did you use ? The 94 most likely has a 5068. The 98 will probably have a 5521. Different. Will cause issues with the PCM.

OH the stories I could tell about connections....

I put in the 5521 pump. It runs like a top.
