so i got my headers put on about a week ago. The guy that did it said he had to make 45 degree boots for two passenger side plugs because they were too close to the header.
the driver side is fine, but i noticed sparks shooting out on start up when i was washing my truck tonight


any thoughts?

Holy crap batman. You need to fix that asap. I would start with the plug wires he made.

just follow the sparks... starter is on pass side of the motor, right above the oil pan...

look around where the wiring connects to the starter, you will find it.

Could be that the postive battery cable is loose on the starter terminal and thats the arcing from the loose connection.

I hope you don't have a fuel leak :doh:

I wouldn't during running and it probably wouldn't turn over very well by the starter.

Sparks is most always bad plugs/wires.

Did you even watch the video? The spark happened during cranking and went away after it was running and the starter disengauged. :doh:

Aside from those facts, when have you seen a high volt low amp arc flash like that? What you saw there was a low volt high amp arc.

Take off the passenger front wheel and you will need a ujoint socket extension. When my tranny was replaced they did not tighten the lead from the starter and it welded the nut on the terminal and i had to get a new starter.

whomever put your shit together... has something hitting one of the studs on the starter... the sparks you are seeing is it being grounded against something it shouldnt be touching..

kind of like putting a screwdriver across both terminals of the battery...

get it fixed asap before you do damage.
Cookie for you! haha
It turns out it was the starter shield touching the positive of the starter. There was absolutely no room to work with, but managed to get under and move it about a half inch away. all good now, starts alot smoother too. Glad i got it figured out before my tune tomorow.
Thanks guys

I just watched it, didn't realize it was a video until now.

But...I have never seen a low voltage arc like that. I'm surprised it was starting as well as it was. I guess weirder stuff than this happens though, glad he figured it out before the thing caught fire.
