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.

Fuel system ,gasoline delivery : fuel pressure regulator was leaking, on my 2003 Chevrolet Impala ,3. 4 liter engine. The car has 41000 miles on it. This may be the same problem as NHTSA campaign id 04v090000 which involved a recall of 2000 Chevrolet Impalas with the 3. 8 liter engine for leaking fuel regulator.

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.

On 7/2/2000 I was returning home from a trip and my car went dead while I was driving along at about 35 mph. I was about 5 miles from home when this happened so I got the car off the road and contacted modern Chevrolet in winston salem nc on Monday morning and had them pick the car up for repair. When they contacted me the same day they told me the fuel pump fuse had blown out and my car was ready to pick up. When I picked the car up they told me if the fuse blew out again that I may need to have the fuel pump replaced. This repair cost me $150. 00. On August the 20th, 2000 I was on the way home from a trip with my cousin and we were about 150 miles from home traveling east on I-40 at about 65 mph when the car went dead again. I managed to get the car off the road and get assistance to get it home. I left it at modern Chevrolet again for repair. Thay called me the next day and said the fuel pump needed to be replaced so I told them to go ahead. As it went the fuel pump and the sending unit both needed replacing. I told them I wanted the parts when they finished. When it was all over this cost me $1050. 00 in repair and towing. When I received the fuel pump and sending unit which I had to ask for as they didn't leave it with the vehicle I found the wiring to the pump had shorted out some how and the ware was bare for about an inch and had shorted against another wire. This was an in tank fuel pump and sending unit and I feel I was lucky the vehicle didn't catch on fire. I have the fuel pump and sending unit if it is needed.

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.

I found two vehicles that had the fuel pump harness with melted wires. I thought this would be of interest to the ntsa because of possible fire hazard.

GMC in recent years has replaced most of the fuel lines on its vehicles with a flexable nylon fuel line. This was done to save money and make installation easier. The metal end fitting are just attacted to the lines by shirnk rapping the nylon line to the fittings. As per gm's own service manual these nylon fuel lines are very vulnerable to damage from chaffing, sharp objects, heat. The service manual states that these fuel lines must not be exposed to temperatures above 190 degrees f. For more than an hour, or 235 degress at any time. The engine compartment environment of this vehicle can far exceed 235 degrees f. I have seen the lines soften from exposure to heat and the shrink rap at the metal end fittings relax. These lines are used before the fuel pressure regulator and are exposed to the full fuel pressure that the fuel pump can generate. This can blow the ends right off the nylon lines when they are exposed to heat above 200 degrees f. This can cause a major engine compartment fire since there are several ignition sources (electrical spark and auto ignition from heat).
