3406E won't fire up.

As little cat said if it didnt try to start the either never got to the motor
Don't b scared of the either it won't hurt ur motor trust me iv got pissed at some of our trucks and tryed to thrash them with either haven't been successful yet

 

If it's got air trapped in the fuel rail and u don't have a primer pump u can pull ur hair out or start it with the either keep it running with the either till all the airs out
Or put a battery charger on it and crank on it till u burn the starter up trying to get it out
Good luck

 

Check power to the ecm along with the ground.
4 is constant power, 5 is battery ground and 6 is keyed power. Check these three wires and that will alleviate that concern one way or the other. Next crack the return line where it meets the filter head and crank the engine, if not fuel comes out while cranking you have fuel issues, if fuel comes out then it's electrical. It's really that simple and will tell you what the problem is.

 

So ur saying no or low fuel pressure the cam won't fire the injector ?

 

Yes sir ur welcome

 

Yes they are the pins on the ecm. The cam does not fire the injector, the solenoids do. The solenoids allow the fuel into the injector where the cam forces it into the cylinder. The engine starts and stops from the ecm telling the injectors to fire or stop.

 

im going to leave this one alone Bahaha

 

No that's not what I'm saying , the injector won't have enough pressure for lack of fuel to Pop off.
