1981 5.7 Diesel delay to shut off

Hello Everyone,

I have a 1981 Chevrolet Caprice with the 5.7 Olds Diesel. The car starts and drives great. My problem that has occurred in the past month is that when I shut the car off, it takes about 5 - 10 seconds for it to shut off after the key is out of the ignition. I looked at the pink wire going to the injection pump and when you shut the ignition off, the pink wire shuts off to. This is telling me that the problem may be that the shut off solenoid in the injection pump is possibly sticking? I don't know.

Well I got a new fuel shut off solenoid today and installed it in the injection pump cover. Cost around $ 60.00 for the part. Fixed the problem right up. Got the fuel shut off solenoid from Diesel Care and Performance. Here is the website page 12V Shut off solenoid - Stanadyne pump applications, Diesel Care and Performance Inc

There was a diesel caprice coupe for sale within the last year or so in northern Iowa. Looked nice in the photos except for the horrible 70's carry over color scheme.

A few years ago there was a Parisian diesel coupe for sale in western WI. Looked pretty beat, had a greasecar kit on it, and was asking like $5k.
