Was driving down the highway cruising along at around 80mph,truck lost all power and wouldn't start back up. Read to do the crank sensor and put a new on in, nothing changed. Have since done
cam position sensor
Throttle position sensor
coil
Full tuneup
Checked and made sure the asd is functional. Side note if I toggle the asd by manually opening and closing it it starts to come to life but quickly dies

I'm am legit stumped and beyond my knowledge as thus far. It's my only means of hauling and to work so any input would be awesome.
Also it does have spark and fuel pressure, seems like it's all coming on at the wrong time

 

What brand sensors? If they aren't Mopar that could be your problem. Sounds like the ASD relay isn't being turned on. If the truck is stone cold will it start?

 

Autozone, but only used them to test a theory and what exactly should the asd be doing? I can clearly see the relay pulling in with key on and starting. As for it being cold startup it will literally not turn on at all....

 

No power at all to anything?

 

I have power everywhere I should I have spark, injector pulse and 50lbs of fuel pressure. Turns over good but never fires. Sometimes I don't always have spark, it's very intermittent

 

Any codes?

Nope no codes, leads me to believe its the ecu

 

Verify spark, and injector pulse. See what's missing.

 

Ok verified everything, decided to jump 30 to 87 on the asd relay circuit and it wants to fire soo bad, like it will legit almost idle but die once you let off the starter

 

Also if held under wide open throttle it goes up and down from like 350 rpm to just about 600 rpm and only at wide open Throttle
