The fuel pressure regulator in the engine compartment developed a severe leak. The leak caused fuel to be released in large quantities directly into the upper intake manifold and out the throttle body. Fuel continued to flow out into the air cleaner housing and eventually the engine compartment and onto the ground. Several gallons of fuel were discharged in this fashion. The vehicle was running poorly but gave no indication that there was a leak until the air clean was opened. The part that failed was a standard motor products part number pr216t purchased from rockauto.com on 5/15/2013 and installed shortly thereafter. Vehicle mileage at installation was approximately 131000. The part failed on 10/20/2014 at vehicle mileage148243 miles. The part was installed to correct a similar situation involving a much less severe leak in an older part. The fuel leakage with the older part did not escape the upper intake manifold. Age and origin of the older part are not known. The older part may have been original to the vehicle. Given the significant quantity of fuel discharged and the repeated nature of the failure, I feel an investigation is warranted.

A yr. Aft. I bought my 2005 monte carlo, things began going wrong with it. First 2 things to go:the cruise control & re-window defroster. The next yr, while driving at night on the interstate, I switched my lights to brights & within seconds I had no lights at all! This could of caused a very bad accident, I was able to quickly switch the lights back to dim & luckily they came back on. Since then, I no longer use the bright lights, for fear of my lights not coming back on. Then it seemed like everything went haywire after that, odometer showed that I was going 110, gas gauge quit & temp gauge registered past 260. Not a fun night to be driving, not knowing my correct speed, how much gas I had, if my car was going to overheat or have no lights! Since 6/15/2012 the tach now registers between 6000-7000 rpms & none of the gauges are working properly. My car also smells like it has an exhaust or fuel leak which comes thru the vents, it makes me sick & gives me headaches. I took it to a dealer a yr. Ago, paid $98.00 for them to tell me they couldn't find a problem. To this day, my car still smells like gasoline, I pray it doesn't catch on fire. Tonight I've been researching these problems & found that the faulty gauges is a very common problem with these cars & quite expensive to fix. I feel chevy should be held responsible for repairing this problem & all the others, after all they're the ones who built a car with many serious problems. This is very unfair for the many consumers out there who have spent their hard earned money to buy this car. Not everyone can afford to get this fixed along with paying the car payment. I don't understand why they can't be made to take care of this. What would have to happen in order to make them pay? What's listed above? A crash, fire, injury or death? Shouldn't have to be that way, something needs to be done before any of that happens!

Filed Feb 15, 2012 · Fuel system, Steering · 90,000 miles · NC

Tl* the contact owns a 2004 chevrolet monte carlo. While the vehicle was parked the contact turned the steering wheel and heard a clicking sound in the steering. The vehicle was taken to an independent mechanic for diagnostic testing who stated the steering knuckles detached from the vehicle. The vehicle was repaired. The federal safety agency recall campaign id number: 09e005000 (steering) may be related to the failure. The contact also noticed fuel leaking from the fuel regulator that could be associated with the federal safety agency recall campaign number: 07e021000 (fuel system, other:storage:tank assembly:pressure relief devices); however, the recall was for an after market pressure regulator. The contact confirmed that the vehicle had original parts. The manufacturer was made aware of both failures and stated the VIN was not included in either recall. The vehicle was not repaired. The approximate failure mileage was 90,000.

I have a 2003 chevy monte carlo ss. On july 31, 2009 the vehicle stalled while on an entry ramp onto the garden state parkway. I lost power steering and braking but was able to pull over to the shoulder and restart the vehicle. Over the course of the next several weeks the vehicle would stall intermittently either at stop lights, approaching stop lights/signs, while turning in the middle of intersections or while highway driving. I initially took it upon myself to pop the hood and see if there were any obvious issues. I noted a leaking fuel fitting that would spew fuel when moved around in the slightest. I brought this to the attention of my local chevy dealer. They replaced the whole fuel line (I was told they cannot just replace the little plastic fitting), the fuel injection system was 'serviced' and I was told my steering column had to be replaced because the knuckle joint was about to snap because it was almost fused. Several days later the stalling issue arose again. I brought the car back to the dealership and they had it for 2 days (I even let their mechanic take the vehicle home in the hopes of reproducing the issue). They were unable to offer a solution because they couldn't have the vehicle stall while in their possession. Several days later it again stalled. I contacted gm corp. And they said that I need to bring it back to the dealership again to look at. This stalling issue does not happen frequently enough to be able to diagnose while in their possession and I am being told that there is nothing that can be done. I have no confidence in driving the car because I lose all power functions (I.e. Steering/braking). The vehicle only has about 65,000 miles on it and has been maintained properly. The dealership even told me the car is 'in good shape'. This is a serious safety issue and a potential threat for accidents.

What is wrong
On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
Risk
The backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
Remedy
Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004. Owners should contact buick at 1‑866‑608‑8080, oldsmobile at 1‑800‑630‑6537, or pontiac at 1‑800‑620‑7668.
