Hi Folks,
Have a problem w/ engine run-on. FPR has been replaced w/ new. Have my suspicions one or more injectors is dripping after key is off. How to diagnose? Any good suggestions please? Thank you.

Bert

How do you know they're drippng? Is it leaking from the lines?

The fact of the matter is I don't know anything except that stupid car is dieseling and I want to fix it. If I do see any fuel puddling I will focus on that (those) injectors, thanks.
Do you have any other suggestions for the problem at hand? Love to learn something. See ya.

Autozone will pull codes for free. That may help point you in the right direction. Does it do it all the time or just when hot? How hot does the engine get?

Best way to tell if injectors are leaking is to attach fuel pressure gauge. PSI should stay within 5-lbs. after shutting down engine. If it drops below that, you've either got leaking injectors or a bad check valve in fuel pump.
