Grand Prix :: 2000 GTP No Pressure In Fuel Line - Click Or Clunk Noise In Gas Tank
It is the 2000 GTP 2 door. It is my sons car and is dead in front of my house. Changed the fuel filter as it is cheap to do. At the check valve there is no pressure in the fuel line. I turned it over with the hose off the filter it did not pump any fuel. I do hear a click or clunk in the gas tank when I turn it over suggesting it is getting power into the pump.
I almost went and bought a pump but do not really want to put the $230 + tax down without checking the resistor after reading around the net.
Grand Prix :: 1997 GT Running Extremely Rich And Pressure Build Up In Fuel Tank
I'm having this weird problem with my car, 90% of the time it will start to run rich, until it reaches normal temp, to the point that I can smell it coming out from the exhaust. LTFT is at around -15% and it seems to go down after cruising for some time but will go back to negative at idle. My first suspect was the FPR so I checked it and found no gas smell on the vacuum hose, then I decided to run the engine with the vacuum hose disconnected and see if any fuel would come out, 5 minutes later and it was still dry.
There is a chance that the MAF sensor is bad, I'm 90% sure it is, because it will sometimes read 2.9-3.1 gps at idle and according to the rule of thumb of 1gps per liter of displacement, it shouldn't go that low but I might be wrong about it; I disconnected the MAF and the smell was still there, today while driving it was reading 5.45gps (A/C was on) and the smell was still present; car also feels sluggish from time to time only at normal operating temperature (which I assume is because of it running rich).
There is also a vibration felt through the steering wheel only while idling in gear at all temps. Today when I got home and after I turned off the engine I heard a noise like water was running. It was coming from the car so I tried to find where the noise was coming from and it's from the fuel tank. I removed the fuel cap and lots of air came out (or sucked in?). I reinstalled the cap and pressure started to build up almost immediately! I have a video, which I'm sharing, so you can see what I'm talking about; I was even able to hear the fuel tank expanding because of the pressure inside, not sure if you can hear it towards the end of the video (when I put the phone under the car). [URL] .....
It also happened today that I was cruising and the engine hit the rev limiter after I stepped on the gas (WOT) to overtake another car. I immediately removed the foot from the pedal and gave it less gas and it acted normal, no slipping from the transmission at any other time. There is one more thing that I'm not sure about it. Every morning, the engine will sputter for 1 or 2 seconds after starting it but it will be fine for the rest of the day. I once tried disconnecting different sensors from the engine and the only one that seemed to make a difference (it didn't sputter) was the TPS.
Things done so far:
- I replaced the EVAP purge solenoid (P0441 was present) back in february.
- Rubber pieces at charcoal canister also replaced, old ones were rotted to the point my hands would look black just by rubbing against the hoses.
- Upper intake manifold was also replaced by me in november last year.
- New NGK spark plugs and OEM spark plug wires last december.
- Cleaned the MAF sensor with MAF cleaner, no dice. Used brake clean, no change. It's a reman Cardone from autozone, which tells us it's 90% sure it's broken.
- New Duralast MAP sensor back in 2010 because a mechanic broke the original.
- 10qts transmission fluid and filter replacement 2 weeks ago.
- Fuel pump was also replaced back in 2009 maybe, can't remember the exact year. The old one would start making some kind of a hissing noise after prolonged driving.
NO DTC'S PRESENT. I once checked Mode $06 data with a mid-level scanner I have (AutoXray EZ-scan 6000) and saw a test had failed, I think it said something about the MAF and EGR. IHaven't connected my fuel pressure gauge tester. Since I can smell it running rich, I didn't think it would be necessary. I'm thinking that there could be a problem with the EVAP system that's causing the excessive pressure in the tank but I'm not sure what that could be. Is there any chance that the pressure is also causing the rich mixture?
Grand Prix :: 1997 - Hissing Noise After Turning Engine Off
I've been fixing things here and there (hub bearing, struts, etc.). My latest repair is the water pump, it was howling for a few seconds during cold starts; I just replaced it today, hopefully this unit lasts for a long time.
A few days ago, I noticed this hissing noise after I turn the engine off at normal temp. Since there was a leak from the radiator drain, I thought that was it and didn't care about it. I just installed a new o-ring on the drain cock along with the new water pump. Test drove the car and it turns out the noise is still there, is it normal or not, I didn't put much attention before.
The noise can be heard from underneath and above the engine, it kinda seems to be coming from the intake BUT I find it weird since I installed a new upper intake manifold in november of 2013. It's a Dorman unit and I followed all the instructions from the kit and the workshop manual. Lower intake manifold gaskets were replaced back in november 2009 after the engine was rebuilt because of a cracked head (not sure what type did the mechanic use, back then I didn't know much about repairs). It's hard to believe that these gaskets have failed already. I also replaced the coolant elbow almost two years ago after the belt tensioner assembly failed.
Grand Prix :: Power Steering - Red Fluid Coming Out Of Line Behind The Radiator
I noticed red fluid coming out of a line behind the radiator. The line runs directly into the bottom of the radiator. Is that line the lower pressure or high pressure power steering line?

I have a 97 GTP. When I am at idle, I get a very loud rattling noise coming from the drive belt area of the engine. The noise goes away when you rev the engine up, but returns immediately when idling. I removed the supercharger belt assembly, and then noise still occurs. This just started tonight out of the blue, and It is extremely loud.

1997 Grand Prix GT N/A. 175,000. I keep getting this code about once every two weeks. I'll clear it and doesn't come back until then. I've had passengers in the back seat smell gas so I'm suspecting the vapor canister. Would a leaking canister set this code off? I checked all the vacuum lines to the purge solenoid and seem fine. Is the canister in the drivers side rear wheel well? I need to get in there and check if it's leaking. I'm having no driving issues however my gas consumption seems to be a bit more than usual. I checked the FPR and no fuel contamination.

Having an issue with my car blowing fuel pump fuses every once in a while under heavy to moderate acceleration. Have replaced inline fuel filter and the fuel pump resister(white ceramic part). Runs fine with normal driving, but when I want to get some horses out of it, it will cut out and stall and once i replace blown fuse it will start back up again, and I'm off and running again.

1997 Grand Prix 3.8 N/A 181,000 ... I have been getting a misfire only on cylinder 4 which has become more frequent. It "only" happens after the car has warmed up and I turn it off for a few minutes, for instance going in to pay for gas. When I start, it immediately starts to miss but as soon as I hit the accelerator it evens out and runs great, every time. I replaced plugs and wires two years ago with stock.
Upper and lower intake manifold gaskets were replaced around 110,000. All three coil packs have been replaced with original GM packs. I replaced my EGR valve last year due to the original was sticking. My throttle body was cleaned about four years ago. I've seafoamed through brake booster and the rest in gas tank.
I'm stumped that it corrects itself right away by giving it gas. The SES light always come on but goes off on it's own after a few cycles.
Grand Prix :: 2001 Pontiac GT - High Idle / Stuck Accelerator After Fuel Filter Change
I just changed my fuel filter and now I am having issues with the idle/accelator. When I get the car going to a speed of 40mph for example, I let off the gas and the speed barely drops. Then when I went down a side street about 20 mph, I let off the gas and the car just kept going. The idle was initally high, but then dropped down to it's normal 800rpm.
The only thing I touched under the hood was releasing the pressure from the fuel pressure regulator before the fuel filter change. I just removed the idle control unit and cleaned it but that didn't work.

Grand Prix :: 99 GTP - How To Lift / Hoist Engine Out
I'm pulling the engine to overhaul. I've borrowed a hoist and think I'm ready to lift the engine out, but I don't know how to strap the engine to the hoist. I first thought of using the brackets with the eyelets bolted to each head and bought chain and hooks. But I had to remove the rear bracket so I could remove the rear exhaust manifold so I could remove that darn rear engine-transaxle bolt. (That really bites because I want to have the exhaust manifolds on when dropping it back in.)
Are those brackets intended for lifting the engine? If so, I could reinstall the back bracket and give it a go.
Searched the internet for info but didn't find much. Did find a 3800 being lifted with two straps completely under the engine.
Also, the engine-transaxle joint hasn't cracked open yet. I'm guessing it's because they're stuck after 198k miles and will eventually separate. But I did not find one of the engine-transaxle bolts mentioned in the 98 FSM: front lower (#1). I don't see how I could have missed it ; maybe the 99 doesn't have it?
Grand Prix :: 2000 With 3.8L Engine Won't Start
I have a 2000 Grand Prix with a 3.8L engine that will not start. When I turn the key to the run position, the headlights and the dash lights come on, but when I turn the key to the start position, the lights go dim and nothing happens. No sound from the starter. I checked the battery and the starter and they are good. I installed a new positive battery cable. Still works the same. Not sure what else to check.
