Fuel Delivery problems of the 2000 Chevrolet Impala

Was having a hard time starting the car at times, especially on short trips in town. Took about 7 cranks to finally get it started. Drove the car the next day, everything seemed okay did not drive car at all over the weekend. Got into the car on Monday and heard a huge noise. I thought the windshield broke. Looked up and saw smoke coming from under hood. Unlatched hood, and saw the intake manifold exploded along with the intake plenum, and there was a fire. Burnt the injector connectors. Car was now at dealership, and Chevrolet was sending an investigator to look at car as this was a possible result from a recall by gm regarding the fuel pressure regulator, which I took to dealer to have it replaced. Hopefully gm will take off this.

I went out to start my 2000 chevy Impala with a 3. 8l engine and upon cranking the engine there was a load bang. I immediately noticed smoke coming out from underneath the hood. I got out and opened the hood and saw that the top of the engine was on fire. I was able to put the fire out with a fire extinguisher. I towed the vehicle to a local dealer and it was noted that the upper intake manifold had exploded and the fire was caused by the fuel line being displaced. Chevy said they are not responsible for the incident even though there are recalls for the 3. 8l engine under the campaign number 04v090000. My VIN # is 2g1wh55k6y9251562.

My chevy impals LS 2000 has been stalling while hot on the parkway. This is a serious situation. This was happening intermintely about every few months, then recently it has become a daily event. Maybe 1 - 6 times a day while on my way to work. The drive is about 30 miles, one way, and it stalls usually toward the end of the trip. I had the throdle body replaced last Wednesday at the dealer, and it did not fix the problem. Before that the gas filter was replaced. This weekend it happened four time on Saturday and four times on Sunday. This is a very dangerious situation especially on the parkway. I have had it to the dealer a number of times and they cannot identify the problem. After these stalls other cars are almost running me off the road. I have been lucky. I love the car and don't want to get rid of it, but if this keeps up I may have to.

The car will stall without warning while traveling at any speed. Has nearly caused 6 accidents. There is no warning proceeding this. It is dangerous to drive on any higway. Have had the car for repair about 8 times. Have replaced: "wires", filters, plugs and sensors without results. Still no correct diagnosis.

Fuel pressure regulator failure 3. 4l v6 engine.

Dealer found raw gas polling on hot engine block. Examination by dealer showed fuel return line leaking due to rodent damage. Return line components are made of a composite material which apparently attracts small gnawing rodents which are gnawing on to the point of destruction causing fuel leaks and also gnawing on electrical wiring. General motor cars parked in this garage for the past 38 have never been damaged in this manner. I suspect something in the composite material is attracting gnawing rodents. Having contacted general motors customer service I was told there is nothing under the hood that would attract rodents. General motors refused to accept that the composite material may be attracting gnawing rodents. Having owned various gm cars over the past 50 years I have never had a safety problem due to rodent damage. Something used in the manufacture of this car is attracting gnawing animals.
