so this is not sc related helping a buddy get his 3.8 stang on the road but there is raw fuel fast dripping out the tail pipe. Is this head related or real bad spark issues any help much appreciated.

Does he not have cats? That's the only way I could see fuel dripping out the tail pipe (vs condensation).
Otherwise, I could imagine the cats glowing red hot as the unburnt fuel gets cooked.

If this guys mustang was catless, I have two thoughts:
* Injector stuck open: floods cylinder. drains out exhaust.
* Spark plug not firing: fuel drips out exhaust.
* exhaust valve stuck open: not likely to cause enough fuel to drip out the exhaust manifold unless the injector was stuck open.

I bet its condensation if it runs ok. The water will smell like fuel if it doesn't have cats mine does it every time I let it sit for a while
