I have a 92' z28. Its a 305 tpi. Yesterday my buddy and I decided to change out my spark plugs...it was time for a tuneup. We jacked the car up and my buddy was underneith the car. He decieded it would be easier to have me get the sparkplug out so he handed me the wrench through the engine. We had not disconnected the battery so when he was handing me the rench it hit the pos terminal of the starter and the other end hit my fuel injection. Im not sure te exact name of it. Its the aluminum pice that branches out into four smaller aluminum pieces and screws into the engine to feed fuel into the engine block. anyways... the wrench made contact with one of the branches of aluminum. It over heated and bursted. Does anyone know where I can get this replacement part or how hard it is to replace? Hopefully I can just replace this one portion of it and not the entire fuel injection. Thanks. Any help would be appreciated.

 

How the hell long of a wrench were you using so that it extended from the starter to the TPI setup? I'm just trying to figure out what you touched, but from your description it sounds like you burned a hole in one of the runners, in which case, a machine shop capable of welding aluminum should be able to fix it. In the meantime, try rigging it with a piece of sheetmetal and duct tape if you need to drive it. Hope this helps.

we were using a pretty long wrench......we needed a lot of torque because the 3rd spark plug would not budge......the original plugs are in there...its a 92' Thanks for the insight....so you think welding it would do the trick over replacing the piece?

 

Erm.. There is no possible way to hit the runners(or any part of the fi for that matter) with a wrench connected to the starter.. theres this huge pieces of metal called a cylinder head in the way(besides other various parts) Are you sure you didn't blow up a piece of the AIR tubing going into the exhaust manifold? That sounds much more plausible. If thats the case, just get it welded.

 

I'm just wondering how you could have disconnected the battery and still have arced from the starter terminal to anywhere

That sounds like as much of a problem as the one you just caused! Did you remove the negative terminal cable? For some reason... is there more than one cable that runs to that terminal?

AIR tubes are welded onto the exhaust manifold... the fuel runners sit on top of the 4 fuel injectors. I wouldn't think that could be patched so easily either...

I second the motion that you (wakeboardo) hit the AIR pipe. First, FI doesnt look like an aluminum piece that branches into four smaller aluminum pieces. AIR does Second, your fuel injectors dont screw into the engine to feed fuel into the engine block. If you see threads, you are seeing the AIR.
And finally, as pointed out by rezinn, there no normal way you could have gone from the starter to a fuel injector line. (if you had the time, and the desire, lm sure you could, but its doubtful it happened accidentally)

You dont want to drive around for long like this, but you should be able to get it to a welding shop to get it welded closed.
