Does this shut down the starter too the truck turns over and fires when I spray carb cleaner in the air box I will try this tomorrow and let you know so is the key switch bad
Expert:  Dan replied 1 year ago.
The security system will disable the injectors so vehicle will still run on starting fluid. Let me know if relearn helps, thanks.

Didn't do the relearn cleaned the injectors and it started but barley seems like it's running on one cylinder spray carb cleaner in the box while it's running and it smooths right out. What is wrong
Expert:  Dan replied 1 year ago.
It sounds like your injectors are clogged. Remove injector rail and watch spray pattern, if it seems to be weak or inconsistent replace the injectors. Let me know how it goes or if you have more questions, thanks.
