okay so im pulling out into traffic when all the sudden the truck just dies. i try to hurry and start it but it just turns over normally but wont start. i then push it to a parking lot and cycle the key for codes and try to crank it again. it cranks but now a check engine is showing so i plug the smarty in to check codes and it shows a p2149 and p2146 both are unknown along with a p1751 any thhoughts on what theses codes might be?

my mods are as follows:very big fluxes, helix 2 cam and springs, smarty beta 4.4, tst r49, ppe dual fuelers, twins and alot of others.

 

P2146 Generic Fuel Injector Group “A” Supply Voltage Circuit/Open
P2149 Generic Fuel Injector Group “B” Supply Voltage Circuit/Open
P1751 Chrysler Transmission Throttle Valve Position Sensor Minimum Range Performance

I would check the wiring harness on the TST, but with your mods there are a lot of possibilities.

 

1751 is tranny related...bad solenoid or possibly just clear the code and it goes away. I've experience it a time or 2.

i would look at dual feeder wiring

 

did you ever run a edge juice on your truck?

 

maybe something in your tst harness?

 

Sounds like a bad harness,you might have to take the tst off and see if that will solve your problems.
