Ran out of fuel / No start

Recommended Posts

2006 LE613 Mack / E7

Truck ran out of fuel coming off the highway.

Added fuel - Filled up filters - Primed Pump 

Tried to start - Driver left Key & Lights on while waiting for me.

Dead battery - Tried jumping Batteries - Changed batteries

Key does not engage starter - No lights at Trans selector - Check fuses at batteries - Found bad wire going into power up fuse - cleaned up all connections

Crank engine - started - Driver shut off - no start

Rechecked fuel pressures - re-primed - bleed out injector lines - has pressure at lines to block

Checked volts at injectors - has 0.3 volts on both sides

Truck runs on Ether assist

Any clues?

Had a similar situation on a freightliner .  Would not stay running until I put air pressure on the fuel thanks and kept it running for a few minutes under pressure.

If it ran out of fuel it may have picked up some junk in the fuel lines running to the engine.  Disconnect the lines at the tank and before it goes into the filter and shoot 5-10 psi air pressure to see if they are clear.

Don't know what happened but didn't see this post until today.....?

did you check the ecm, body control module fuses/relays.  With all the jump starting bad wire stuff you may just have something going on there.  remember that without 10.8 volts to the ecm and the body control module and communication with each other it will try to start, may even start but die after it realizes it doesn't have voltage/communication.  does the LE have the shutdown override switch on the dash? try holding that down and see if it starts and runs with the ecm in override mode, if so its a fault shutting it down(water level oil pressure,etc.)

Any malfunction light? May have blown ecu or vcu fuse.

If you have good fuel from injector lines at cylinder head, it should run unless there is an electrical issue.

Funny thing is it ran on ether but not on its own.

Also noted couldn't connect to DLC

A diesel will run on ether as long as it has compression. Running on its own requires fuel to be injected at the right time.
