Out of curiosity, have you ever checked your fuel pump drive module?

It's located on the rear driver side near the fuel tank, on the outside of the vehicle.

I've had one corrode on the cover, water gets in and when the temperature and moisture change in the fall/spring it can create very sporadic fuel delivery conditions.

I suppose if you have FORscan and actively monitor your fuel rail pressure while driving, you can see if the pressure blips or can't maintain pressure.

Just a quick aside and easy enough to check.

Thanks for the reply. I wish I had a laptop and Forscan. Any idea if my code scanner would give me live fuel pressure data< (I'm replacing the fuel filter today even though I did it 2 years ago).
And as far as the fuel pump driver module...blew my mind to find it had one AFTER IT TOOK 3 FUEL PUMPS LAST YEAR TO CLEAR THE CODE, (1ST TWO WERE AFTERMARKET PUMPS AND RAN THE ENGINE JUST FINE BUT WOULD NOT CLEAR THE CODE.
So you very well might be onto something here with the driver module!
Depending on the quality of scan tool, you may be able to get live data.
Your absolute best bet is FORscan with a laptop and OBDII compatible USB device.

the ones with the MS and HS switches are the best. Can’t remember the name on mine right now, I can go look. But I’d consider getting one.

the drive module has such a poor design and location. I don’t know who decided on putting an electronic on the outside close to a wheel with lots of salt spray. It’s a likely culprit. But I could be wrong!
