No start after EGR delete

[ghostrider112]

I just did an EGR delete and y-pipe

That's weird man, what are the odds to do something so easy and not be able to start after words. I wonder if you cut a wire when removing the turbo and re installing it. I'd grab a volt meter and start checking wires buddy

 

[ghostrider112]

Aight guys, truck will start on wd40 but will not rev up at all. When the pedal is mashed to the floor it just blows black smoke. However, it doesn't die. It doesn't sound like its running on all 8 though.

 

[ODAWG714]

Check your injector harness's that plug to each injector and triple chek the ficm. Any injector codes?

 

[G Racing]

Check for a bent pin on the ficm

 

[ghostrider112]

I've checked the injector harness, no frayed wires and all connections are good. The FICM didn't come off so I don't think any pins will be bent

 

[ghostrider112]

No injector codes either

 

[ODAWG714]

I'm stumped, where u guys located

 

[ghostrider112]

We're on Mandeville, LA

 

[ghostrider112]

Now it's throwing injectors codes on 3,5 and 8.

 

[ODAWG714]

Try a different ficm man, I have a feeling you guys may have chaffed a wire possibly. It can and has happen.

 

[ghostrider112]

I wish I had another FICM to throw in there. We're pulling the injector harness out right now to check it, make sure it's all good

 

[ghostrider112]

Every wire in the injector harness is fine. There are no cuts, chafes, broken pins anything. All wires are tight, and fit tight at the connectors. Words cannot describe how aggravated/pissed I am at this whole situation

 

[ODAWG714]

Check your fuses? Incase under any circumstance you shorted a wire and blown a fuse?

 

[ghostrider112]

I'll check fuses. I don't know why 3, 5, and 8 would be dead. I could see if it was 3, 5, 7 then I'd say for sure the harness was bad after 1. But it's just random injectors

 

[ghostrider112]

Wiring harness checks out fine

 

[Stroker#66]

Have you been able to check live data with a scanner yet?

 

[97strokn&smokn]

It almost has to be your ficm the black smoke when cranking and the weird inj codes. I would say one of the ficm harnesses is not plugged in all the way.

 

[ghostrider112]

Checking live data tomorrow. Haven't got a hold of the scanner yet. It only dumps black smoke after being started on wd40 with the pedal to the floor but it doesn't rev up. The FICM is plugged in all the way and checked out with 48v.
We didn't even touch the FICM during the install. I'm thinking about throwing a new harness on it

Check the pins on the actual FICM, and on the injectors throwing the codes, the harness isn't going to become faulty that quick, it will show symptoms. Does the buzz from the injectors sound quieter or weaker than before? Clear codes, try and start it, if the codes come back, you have damaged pins, or the connectors on the FICM/injectors are not all the way in. Check, check, and re-check. Something was dislodged during the install.

Edit: if the FICM is plugged in from the engine harness connector, it will still read 48 volts. The last two connectors connect each bank of injectors (1,3,5,7) (2,4,6,8) so a combination of those two could be loose and still read power on the FICM. Did you remove the intake manifold entirely when you did the delete? If you removed the injector harness when you pulled the manifold, ensure you did not bend one of the four pins inside the connectors when you re installed the harness. Best of luck.
