What year car?



It could be the famous pulsation damperner problem.

It is an 86 GXL

So I should only have to replace what is fried and the pulsation damper and I will hopefully be okay.?

leaky gas or oil could have collected on the lower intake and ignited from the heat of the engine. If you have insurance you can file a claim and they should take care of it. Make sure to tell them you saw flames and not just smoke. I had a small engine fire in my Jeep a couple of months after I bought it, and the insurance company took car of it with no problem. This was good because if took the shop 2 weeks to repair it and cost over 2000! Actually a couple years after that I had an electrical fire in the Jeep caused from a grounding wire in my dash. It melted the **** out of my harness, BUT the insurance company didn't want to pay for it because I never saw flames, so it wasn't considered a real fire. They eventually reimburse me, but not for the full amount that it actually cost. Luckily a friend of the family did all the work and did not charge me any extra. This was on his spare time however so I didn't have a vehicle for like 6 weeks. The insurance paid like 960, which was a lowball estimate they rounded up. It really should have been twice as much with all the labor.

I would replace the fuel rail with an 89-91 NA rail. It has integrated pulsation damper that won't leak like the 86-88 part.

I've heard of those s5 rails not mounting right on a s4 engine. have you done that?

that sux a nut

The primary rail seems to fit fine. I was able to bolt a S5 TII primary rail to an 86-88 NA intermediate housing.

cool guys thanks for all the help I will let you know what I find out tomarrow when I clean off all the chared mess. How much of a pain in the ass is it to replace the wire harness with everything still being in the car.?

I find NAs a little more work, but its not hard. You'll need to remove the upper intake manifold, lower intake manifold and maybe the PS/AC bracket to get to all the connectors, but it really isn't that bad..it shouldn't take more then a day...do you have a service manual?

Oh yeah I think my alternator maybe fried does any one have an idea what that is gonna cost me ?

NAs are plentiful for that year at the junkyard, you should be able to find parts cheap if you take your time and look. The hardest would be the eletrical harness to fix. I would probably just get another used harness.
