The dealer thought it was the fuel pump, replaced it, and it's still not running right. But it does start and run now at least. They don't know what's wrong with it now.

How much weight were you towing? It doesn't help that your lifted with larger tires. The bigger tires make the engine work harder causing the weight you can pull to go down a hair. I could never pull a trailer with my 4.7 liter and 34's unless it was small and only weighed a few thousand lbs on flat roads with no hills

It was about 14' enclosed tandem axle. It was empty, so probably 3000-ish.

Now they're saying everything points to the FCM needing replaced. Another backordered part, no idea on ship date.

You could try a few local scrap yards... pull one from a donor vehicle.
I thought they needed to be VIN programmed but guys on JF have been installing them plug&play style to fix the recall issues
Yup all plugs and play. Did the QT I to QT II swap on a V6 back in the day and it was all plug an play

Sorry to jack the thread, but I was unaware anyone had successfully done this swap. What all was needed to go from QT-I to QT-II?
