I Just had injectors replaced, and I think it got to like 40 degrees last night, well when I went to crank it this morning it turned over fine, smoked like crazy and would never hit on anything, just kept turning over and smoking real bad. what do i do?

GPR? Is it throwing any codes?

My FICM threw codes of low voltage inj 1-8.

Did you have all 8 injectors replaced? My dealer did 2 at a time and each time the truck would crank for a long time until they swapped out the next set of injectors.

plug in your block heater if its not starting and its cold out, i have to plug mine in if it gets in the 40s. check to make sure the cps is plugged in, wiggle the wires. Just throwing this out there, it worked in my case
