Intake blows to pieces..fire erupts

How's it hangin' fellow GP owners? :th_nervous: Well, as the title of this topic indicates, my '01 GT is no more. I went out to start her yesterday and the intake blew off the engine, shattered into a thousand pieces, sent schrapnel flying everywhere and a fire erupted. What a friggin mess! No injuries to report other than a few dents in the siding where some flying pieces had hit the house!

The car's been acting up with throttle issues (wacked out revs on idle, stalling after a 5 minute idle) so I had it parked since Christmas moving it only to let the snow plow clear the driveway every few days. Well, yesterday it wouldn't start at all as it wasn't plugged in (temps were -30 C plus wind making in feel like -41* C) . So I hooked it up to the truck for a boost and when I hit the ignition key well, that's when all hell broke loose. Several handfuls of snow later, the fire was out and my poor baby was toast. After what I'm assuming was a full on backfire of sorts, what other engine parts are damaged?! Who knows what happened to the valves and/or timing belt and/or other items when she blew with such force. Better to replace the whole engine then to start replacing one thing at a time is my thought.

OR....

Today, I stopped in at my local Pontiac dealer but I didn't even bother to stop at the parts & service counter to ask how much it would be to fix it. I walked straight to the used car, er, previously owned section and there was a beauty of an '05 GT waiting for me. Gonna make a few phone calls first but probably take her for a test drive tomorrow. A little fire doesn't scare me! Once a GT Gurl...always a GT Gurl! :th_winking:

wow, glad to hear no one got hurt. thats a first i heard of something as bad as this happen. only other things i had heard of are engine fires due to leaky valve covers or fuel o-rings cracking.
 
Zero mods. Strange huh? I've never seen anything like it. I've seen a carb get blown off it's bolts and catch fire but never such a thing on an EFI. I'm still in shock although the thought of that '05 on the lot is starting easing the pain!

Sounds like you had a stuck open injector and somehow got a backfire up into the intake manifold. I've heard of similar things happening on other cars, but never on the 3800 until now.
 


Well, I'm back! ...thanks for the email reminder admin!...

Bought that 2005 Grand Prix I was looking at back then.. but I may have to change my login name to GP Gurl as it's just a base model...no GT's no GTP's.. There are a few GT features I really miss but all in all, I love the GP all around. People called me crazy for buying another Grand Prix after the previous one exploded but what the heck...I like to live dangerously!

The conclusion was that there was a faulty fuel injector or "residual fuel on the rails" ..though I'm not sure what the latter means...maybe from the dead battery, and trying to turn it over several times before the boost, the fuel pump was still pumping? I dunno...

What I have learned from this is that I will never, ever, in a million years, stand in front of any car that is being boosted. If there was someone standing in front of mine when she blew, they would be dead or certainly severely injured. I think of every other boosting I've received or given...one under the hood checking the jumper cables, the other in the drivers seat..'ok..try it now.." KA-BOOM... Ya, so NEVER STAND IN FRONT OF A VEHICLE BEING BOOSTED.

End of Public Service announcement! ;)

I'm sure if I have any issues with the '05, I'll be in touch fellow GP'ers.

That's why you do a top swap for the supercharger, its aluminum and wont explode into tiny fragments... plastic can give way, seen 2 destroyed at the dealership, 1 melted, 1 exploded.

glad your ok, glad your in a GP, and glad your back
