While the regulator doesn't appear to be the cause... call GM and have them check if yours was ever replaced. Since the fuel burned.. it'* possible that it was the cause.

The upper intake manifold shouldn't contain any comubustible substance, only air.

Ron, here'* the info on the FPR Recall, though it is specific to the '98-2000 L36 only

Even though yours is not listed in the recall, it doesn't mean that your FPR hasn't failed. I agree with BB that you should get it checked before putting things back together.

Other than pulling a vacuum on the FPR how can you check it for leaks?

My guess is that number 1 or 2 injector was leaking down and left just enough fuel to explode.

Ron.. check that FPR recall. Matter of fact is..GM won't spend time diagnosing it if the FPR was a recall item.

Any one have any luck with GM paying for any repair cost?

Sounds like I may need to send GM an email so I will have a record.

Zuper8 was recently paid for her car in full.

here it is.. although I think the actual payment was somewhere else.

toss a PM at Rachael and she can probably give you most of the information for contacting them that you need.

Thanks to every one for all the help.

This has all most been too much trying to take care of my father with terminal Lymphoma and now this.
My only other vehicle is a 1975 Chevy truck and the gas tank sending unit stopped working yesterday a few hours after the manifold explosion. Strange.

For these cars you may want to call GM and see if they have an updated program for the PCM to avoid the Backfire through the intake.. They may be able to reflash... Some of the L36'* outside of the 98+ have been known to have this issue... This was not the case on the 95'*...

There were 2 issues assoiated with the upper intake exploding, one was a backfire through the intake... The other was a leaky fuel pressure regulator...

Just imagine you go to turn the car over, and you have an injector spraying fuel and in that instant with the valve still open you get a rouge spark....... KABOOM...

Have you chatted with GM at all yet?

Thats what I was going to say. My 96 PCM was reflashed by GM per a campaign recall to avoid the backfire and exploding intake.

I just called the Buick # 1-866-608-8080 and was not able to speak to any one.
Every time it is supposed to transfer me to a person they hang up.
