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.
View 2 RepliesRadio is fine, all gauges and such seem to be normal. The climate control unit displays 75 degrees, the fan is blowing, but none of the controls do a darn thing. I can't turn it off, up, down, or anything. Where to start looking?
View 1 RepliesIt 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.
Ok so I just bought this car, 1993 pontiac grand am se, from a neighbor. When I test drove it, the back seat was all unscrewed so I thought no biggie and it drove really nice for being a 1993. Ended up buying the car. I get the car home, husband puts seats back together and we go to leave for town and the fuel pump fuse blew. Put a new one in, go to start the car, fuse blows again! Tow the car home. Husband checks the wires to make sure there is no faulty wires. Has to reground the ground wire. Car then starts. Go to drive down my driveway and the dang fuse blew again! Mind you there is a new fuel pump in the car so we know this isn't what is wrong with it.
View 4 RepliesI bought my 2001 Grand Prix with a 3.8 liter (non supercharged) earlier this year. Within the first month, the check engine light came on with a P0410 code. Took it to the shop here at the auction that I work at to get repaired. He ran the diagnostics on it and found that the air pump wasn't working. He pulled it out and it was full of water, due to the air inlet being so low. So, he replaced the air pump and re routed the air inlet so that it was higher up into the engine compartment. That same night, the light came back on, so I brought it back in the next day. The relay failed and popped the fuse. Replaced both, and the light was off for a full day.
Got ready to take it in for its emissions test today, and the light came back on again. The air pump is not working, again. Turns out that the previous owner had replaced the air pump twice (once with aftermarket, and once with an OEM unit) because of the water build up and freezing the first time. I am not aware of any GM service bulletins, but there has to be something that is taking out these pumps. The only things not replaced on the secondary air system is the lower check valve and solenoid. So, what could be causing the pumps to fail prematurely?
I am a proud owner of '97 Grand Prix GTP, it has always been a great car with really low maintenance for me. A few days ago I noticed a mild fuel smell and I checked the gas cap, the external fuel filter, etc... Then I lifted the hood and I saw that one of the two fuel lines that run between the firewall and the brake fluid reservoir had a seepage leak in front of the factory loom that secures both lines before going over the supercharger and on to the fuel rail. A fuel leak needs to be repaired immediately, so this is where I am so far.
I noticed that the leaking fuel line is actual a rubber/plastic fuel hose that is covered by a plastic heat proof cover that protects the hose. It runs from the firewall to the fuel rail along side another fuel line of the same size (a supply & return line I believe). Just before going over the supercharger they both have quick connect metal ends that meet two metal fuel lines that end up at the fuel rail. My current issue is that this plastic/rubber hose section of fuel line is discontinued and no longer available to order according to my local GM parts dealer. The way I see it, hunting down this part can be Plan A and Plan B can be duplicating this hose by making it with high pressure fuel injection hoses and the appropriate quick connect fittings.
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.
View 13 RepliesI have a 2000 GP GTP. I went over a speed bump to fast one day, and parked my car. When I got back into the car the next morning, I tried to put my car into drive and it wouldn't accelerate or move. So I put it into lower gear, 1st to be specific, and the car moved normally. I drove like that for a few days with no problem. Then days later I did the same thing, went over a speed bump to fast and now the vehicle wont move at all unless I put it in reverse.
View 2 RepliesI have had this car for about 6 months and it already had 1 problem with starting becasue of the key error (easily fixed)
now, like it says in the title it is turning over, lights work, taking fuel, but not starting. It might be flooding but i think that the fact it has a new engine (well I got it changed right when i got it)
I have a 2000 grand prix gtp, I am trying to pull the motor so i can change some things up so i can race it. But how to pull the motor or transmission with it.
View 7 Replies2000 Grand Prix GTP has code P1629, car will run for 3 sec with black master key and then die. Security light in dash is flashing when this happens. Tried the 30 minute relearn for PK3 with no luck. It will start and stay running with the grey Valet key which is perplexing to me. As of right now I am siding with replacing cylinder and ignition switch after everything I've read on the subject.
View 13 RepliesCooling Fans and a/c compressor not working-2000 Grand Prix. They both work when I jumper them. Replaced coolant temperature sensor, checked fuses and relays -all good. Not sure what to troubleshoot from here.
View 4 RepliesI'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?
I have a 2000 Grand Prix 3.8 with 65,000 miles. Bought the car new for the wife to drive. The front brake lines rusted out. My wife has a friend who is a backyard mechanic. She had him replace the front brake lines, from the abs block to each front wheel. Well she finally told me that the brake pedal is not right. I went out and sure enough with pressure on the pedal it goes to an inch off the floor. I bled all for lines at each caliper, no change in pedal. I bled almost a full bottle of fluid. You can pump the pedal for 10 minutes and no change in the pedal. I don't think it is air in the line. I changed the pads and rotors on all four corners last fall. The brake pedal was normal then.
View 5 RepliesI 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.
2001 Pontiac Grand Prix GT/3.8L
I have a 2000 pontiac grand prix (3.8) and when i was driving my car randomly shut off. When i tried to start it again, the car would start, rev a 1000 RPMs then dies a second later. If i pump the gas i can keep it running at around 2000 RPMs until i let my foot off the gas, then it dies After repeated attempts the tow truck was in need. the following day i ran some tests. when starting the car the fuel pressure would stay between 40-50 psi and doesnt drop below that. (excludes fuel pump, filter, etc..)
After running tests the car suddenly started up and continued to run with the rpm bouncing (+/- 100 rpm) i let the car run for 10 minutes and it began running perfectly. This has happened repeatedly in the past 3 days. I have noticed that when letting the car sit while runnig, it will usually die within 2 minutes, however if I am driving. It will sometimes be fine for hours. When attempting to start it by hitting the gas, the car will sometime sputter at 300 RPMs when hitting the gas will do nothing. in some situations i will hit the gas and the rpms will decrease and rise randomly. (letting my foot off the gas, rpms will hesitate before reducing).
When the car dies, i am at times able to get it running after spending 30 min fiddling with it. But half the time it wont start. I have a -P0107 and P0108, codes for high input and output of the MAP sensor. When i unplug the sensor it seems to have minimal effect to the running condition of the car. When i unplug it at times the car will keep a steady rpm while hitting the gas and the car acts no different when i unplug the sensor when the car is running well. I ordered a new MAP sensor which should arrive today so i can see if that is the problem.
So I pulled into my driveway yesterday about 5 minutes after my low fuel light came on and as I was making the final turn around my house the engine cut off. Luckily I was able to park in it's normal spot before coming to a halt.
Anyway at first I though "out of gas" even though I knew I'd driven further with the light on. After putting in 3 gallons still no luck. I noticed with the key on no noise from the fuel pump so I checked the fuse and relay both were fine. I then checked all the other fuses and noticed the large 30amp PCM fuse under the hood was blown.
When I replaced it, it blew instantly. I was able to hear the fuel pump come on for a brief second before it blew out. Unsure if the two were related I then pulled the Fuel Pump fuse and replaced the PCM fuse one more time and again it blew. The motor cranks over but won't fire (not getting fuel.) Where I can start to correct the issue.
2000 7.3L SD .. The check engine light is on and if you hook it up to the reader it kills the engine and if you replace the lighter fuse it has power and if you hook it up to trailer it blows fuse and no power any...
View 4 RepliesI have a 2003 pontiac grand am, getting no fuel, pump won't run. I put in a new pump, filter, and changed the relay. Sometimes the pump will kick on and i can start the car, but not today. Took apart the fuse box and could see no visible problems inside.
View 14 RepliesI had a VERY bad leak, to the point where I would fill it, an hour later it all leaked out. I had a mechanic work on it, and he rebuilt the PS pump, BUT the pulley was cracked, they DON'T make that size anymore. He put a bigger one on, only to find out, it was rubbing on my brake lines so I couldn't drive it! SO I had another grease monkey work on it, went through a few new pulley's FINALLY found one! BUT went through 4 Serpentine belts!!
After 3 months with NO VEHICLE, we finally got it all back together. BUT now it is not all lining up we couldn't tell until we had the belt on. it is about a 1/4 of an inch to much to the right.
I'm thinking maybe washers or spacers would work?
I just bought a new 2001 Grand Prix. I am not completely car savvy, but I know a few things for a lady.
The battery won't hold a charge.
and the computer diagnostic tester thing says the Headlamp Relay is malfunctioning.
