I don't know why direct injection would make any difference. Please do explain.

Moot point anyway. We went from burn plug to wet with gas plug. Clogged injector? Leaking injector? I agree we need to see that plug, but more important...I agree a compression test is needed. No ignition with no compression. Further speculation is pointless without it.

 

Direct injection, the injector sprays into the combustion chamber, the other fuel injection the injector sprays into the intake runner in the cylinder head. I suppose that makes no real difference, a bad injector would still spray fuel, however the DI injector would still have possible dirty fuel rail,
I don’t see how that could happen just after a spark plug change.
I do see how a 14 year old wire could be affected by removing the coil or the fuel injector harness

 

Here are the Brand new plugs after I pulled them when I got home the evening of the Break Down

 

Something broke off the ground electrode and drive it up into the iridium whisker and ceramic part of the plug.
I suggest a look into that cylinder with a borescope camera, bet cha there’s damage to the piston.

 

Yeah. That’s not good. Don’t start it or run it at all till you retrieve the broken parts of that plug.
If you don’t get those pieces out of the cylinder, you’re looking at catastrophic engine damage if you run it. If it hasn’t happened already.
A borescope as recommended but you still need to pull the cylinder head to see the full extent of the damage.

 

You didn't try to "gap" the plugs?

 

I think we have a winner! 41-109 come pre-gapped to .043". Our 41-108 come pre-gapped to .035.

 

I woke up Sick today And YES..... I re - gapped the plugs before installing them ..... they were all set to .035...... I'm convinced it was a Fuel malfunction? Me pushing it 15 miles home probably did most of the damage to the Plug? Every time I checked anything after the malfunction there was a lot of fuel on the plug and in the cylinder ....Even in the pic of the plugs you can see how wet the damaged plug is! I'm not denying That I may have done some Catastrophic damage by pushing it home? I guess I'll find out Soon! I'm so bummed out by all this I just ordered a compression tester on amazon it will be here after Christmas! I'll get back to it after the Holidays....... Thank you to all of you for the Ideas & comments....... I'll keep ya all Posted!

Hope you all have a Merry Christmas and a Great New Year! Thanks again, Tony

 

 

That #1 plug looks carboned up from intermittent misfire and/or low cylinder temp from low compression. Not “burned.”

Do a compression test. Borrow the tool from the parts store if needed.
