3406E won't fire up.

Wow this just gets better by the day
Pull the dash panel the speedo is in and right about the steering column behind the dash panel there's fuse block holds 4 fusses check make sure non of them are blown
If there all good try to start the truck with starting fluid just mist it in the breathers and keep misting in there making it run if it will run on starting fluid but won't start on its own u got ECM problem
The starting fluid will not hurt ur motor unless u just get stupid with it just don't drowned it with it
Just FYI And there 2.5 amp fuses on all trucks thy won't just blow unless u got a short so dissregrad that post

 

I have never seen a shut off solenoid on an e-model cat. Somewhere on there all you have is a relay. He mentioned fuel was dribbling out the bleed. Disconnect the return line and crank it and see how much comes out. If none does then work your way back to see if there is a restriction or weak trans pump.

 

Sorry dead post. You DON'T have a shutoff solenoid. On an e-model. It is just a relay that supplies power to ecm.

 

Will it start and stay running why u mist starting fluid in the breather then die when u stop spraying it ?

 

any chance you know someone that has cat et that could hook up to your truck and make sure the ecm is responding.

 

It will start on either
In stead of spraying it in the breathers on the driver side of the motor in the Middle of the head there's a 4" elbow coming out of the head that goes to the inter cooler on the bottom of that elbow there's a 1/4" plug pull that plug out get someone to cranck the truck why u mist it in there if u do it in the breathers it takes quit a bit before it get to the motor and it will tack out if ur spraying heavy the hole time
