Just installed the Edge Comp today. Took it for a spin. Did a couple WOT passes and on the last one truck just died. Pulled over and tried to crank it over. Cranked but would not start. Did the injection pump take a dump?

Mark,
Is the truck still dead?

Sounds more like you let off causing a stall. Easily fixed by loosening up one or two of the fuel lines at the head then cranking until fuel starts coming out. At that point tighten up and crank again and it will start again.

 

Yes, it's still dead. Had to walk home.
I'll try doing what you said. What size wrench to crack the fuel lines?

Thanks
Mark

 

19mm or 3/4" will do the fuel lines.

 

Ok. I just got back. I cracked a few lines at a time and got fuel coming out of the third, fourth & fifth line back but none out of the one at the front of the motor. I tightened them back down and cranked the motor over and over but would not start. I unhooked the Comp box also and cracked the lines again but no start. What do you think?

trust me take the return line off at the injection pump bumb the starter pump will run for 25 seconds repete many times then try to start if still no worky un hook intake heater and use either

 

Return line? Where is it located?

 

Sounds to me like your injector pump took dirt nap, quit after hooking up comp box. I don't see how you would have to bleed air after just an electronic not mechanical feul upgrade.

more than likely you killed it.

Just curious though......has anyone here had luck doing the "one man" bleeding procedure? Maybe I'm wrong (wouldn't be the first time) but it sound to me like alot of guys here crack the lines loose, go to the key, and then check the lines and keep repeating in hopes of bleeding the system. What I do is to remove the starter relay and use an old "horn" button with spade terminals. I put the horn button in place, and crank the engine from under the hood. That way you can watch the fuel flow begin and tighten the lines as the engine is cranking. Seems to work for me.

 

i have done the same thing to mine the return line on the injection pump it is next to the fuel inlet i have done this before your pump should be fine

 

Any codes?

 

Mike, I don't think I can check for codes without a code reader and I don't have one. Should I get one to check it out? If so, which one should I get?

If unhooking the return line doesn't work in the morning, guess I'll be towing the truck and ordering an injection pump.

 

I think your IP died. Mine went the same way. No codes, just dead.

I wouldn't go unhooking the return line. Crack the supply line. If you have fuel coming out when the LP is running, you've got fuel to the IP. If nothing is coming out from the HP lines, then it might be time to make a few calls for a new pump.

 

I had my wife cranking on the ignition while I was watching for fuel from the fuel lines I had cracked opened up at the head. I did a couple at a time and there was fuel coming out of all but the front two. I didn't try the one at the rear of the motor. If the injection pump was dead, would there be any fuel coming out of any of the lines? Just curious.

 

Generally only cracking open the "easy" ones gets the engine to fire. #1 and #3. I also find that "good" pumps have quite a bit of fuel flow, while bad ones will give you "false hope" by only discharging a slight amount.
