All I could add would be to at least see if the pickup still has cold continuity (ohm it).

To add a bit of clarity, the engine is in a 65 Coronet 'vert. It's run by a Painless EFI system.

There are two different pickups for the magnum 5.9.
Might help knowing which version he has.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Heck if I know. The connector is different but I doubt that's why it got changed, more like it's to ensure you couldn't put the wrong one in.

I've seen stuff ohm out good cold only to fail when hot.
Also, wiggle that wiring while you are ohming it out to check for intermittent opens.
It would be best to monitor the running signal with an O scope as you wiggle the wiring to see if it drops out in use.
A data logger is real helpful in intermittent faults.

If you could data log that signal it would be useful for determining if that's the issue.
there are three lines to the pickup, not sure what they are. B+, GND and SIG?
If you could data log the B+ and SIG, make sure you aren't losing power to it.

If it's a 5.9 Magnum it's 93 or newer

so it is mpi, not tbi. it is a 3 pin halls sensor. not 2.
the 8 shutter wheel is the painless add on, so it isn't just cam position or to know where number 1 is, that actually tells the computuer when to fire.
it was originally set to tell a chevy spark "computer" when to fire, and I got it to work with the megasquirt system without the chevy part.
so it is more important than it was originally.
the computer I use to read the logs is having a battery issue again apparently. it died just as I started logging. will work on that issue and see if I can get back in there to check later this week. I have not fooled with any aftermarket EFI systems but I will soon as my son is super charging his Dart and will be using an aftermarket EFI system. On the factory setup I talked about and worked on at the dealer the MPI 5.9's had the crank sensor to tell the PCM when # 1 was at TDC and fire the ign but it used the dist/cam sensor that had the one long shutter to know when # 1 was on the comp stroke so it knew when to fire which injector. That's all it needed since it still used a dist to distribute the spark to the right plug. Is yours a factory dist with the Painless add on or are you using a different dist ? I think my son has decided on the Holley Sniper system when we add the super charger and EFI to his 400 in his Dart. I think he plans to get their fuel tank and in tank pump setup also. Look like I will finally get to work with an aftermarket EFI after 24 years at the dealer working with factory systems. Good luck with your car , Ron
