4.7 wants to stall

[11ramkelly]

Guys I need help! So I just replaced my fuel pump on my 2011 ram 1500 it has the 4.7 liter. After replacing everything seems fine when I crank it up it idles amazing cranks right up and all, but when I’m driving at about highway speeds, the truck just stalls and engine dies but I don’t lose any of electrical and no engine light comes on, I shut the truck off and it cranks right back up, any idea what in the world it could possibly be??!!!

You just replaced your fuel pump, and this is a new symptom, that appeared after replacing the fuel pump? If so, I suspect that the problem is your fuel pump.

Did you use an OEM Mopar fuel pump, or aftermarket? If OEM, where did you buy it? If aftermarket, what brand?

These days, with all the horrid cheap garbage and counterfeit OEM coming from China, the only way to get good parts is to buy a known quality brand from a reputable seller.

If you did buy an OEM fuel pump from a reputable seller, I'd start inspecting all of the electrical connections that were touched during the replacement job.

So, the cliff notes from part 2 of that video,

The problem was traced back to electrical noise back feeding into the PCM, from an aftermarket ignition coil.

Any aftermarket parts of dubious quality installed near the time this symptom manifested?

Edited to add:
Here is another similar event, caused by an aftermarket car alarm.
