Question about 2002 Pontiac Grand Am SE

1 Answer

2002 pontiac grand am V6 3.4 180k miles. gas smell started when defroster was turned on was told it wasn't a big deal since it wasn't throwing any codes so didn't address it right away. Being winter is here i let my car warm up this morning and when I came out I smelled the gas before i even opened the door. Drove it to work came out 10hrs later started and drove the car maybe one mile to autozone and popped the hood. The fuel pressure regulator was wet and leaking gas. turned car off and it dried up turned car back on and let it run but the regulator didnt leak very much at all. After driving home about 3 miles it was still pretty dry. Car only had one instance where it would not start but was determined battery was bad so replaced that. Other than that it starts with occasional longer than normal crank time and on rarer occasions when starting it makes a sort of grinding noise. Doesn't sputter or stall but do think the transmission is incorrectly shifting lately but that may be my paranoia.

The regulator will have either an O-ring seal or a regular gasket seal. Probably where the gas smell came from all along. Certain conditions may cause it to leak more than normal, but the seal should be replaced. It would be a good time to have your fuel pressure tested, just to see if you need a new pressure regulator as well. Not likely, but it's the right time to check-it will have to be removed to replace the gasket or O-ring on it.
A fuel line leak can contribute to hard starting.
As for any noise or about the transmission, just check your fluid after the car has reached normal operating temperature. If the fluid is at the full mark, and is a nice clear red, nothing else you can do- it will sort itself out. If the fluid is a dark brown, like dirty red, you could try a fluid and transmission filter change. Sometimes helps, sometimes not. Good luck.

Do a compression test. When you over heated it it may have blown a head gasket or cracked the head.

SOURCE: gas smell

There has to be a leak in the fuel system. Has it been checked while running? There will be at least 2 lines. One will be pressure and the other is a return.

Crank position sensor bad?
Are you sure the fuel pump is working? Might be the sending unit in the fuel pump that is bad. Clogged lines, clogged fuel injectors, clogged fuel filter, all things that could be checked.

I only get 15 miles on a gallon of gas, when I try to speed up the car starts jerking and If I puch on the exsalrater it wont speed up and I can smell gas. If I have the heater on it's much worse

If you smell the gas I would have it checked you may be dumping to much fuel into the carburetor or may have a fuel leak which can cause a fire.

So i have a problem with my 2002 grand prix gt it has 120,000 miles on it. i was coming home from work one night and the low coolant light came on it got pretty hot but i made it home. My dad put coolant...

Check for spark at the plugs and check the fuel pressure. Also remove the spark plugs and check for fouled or wet plugs. A plug that is saturated with gas will not spark. Clean the plugs and dry them off and try to start. If all looks good then check cylinder compression to check for a blown head gasket.

1999 pontiac grand am exaust smell

If your blower motor is in the engine compartment, I suspect you did not get a good seal around the housing when you reinstalled it. Usually a foam gasket.
For now, push the recirc button so you are drawing air from inside the car into you heater system. Recirc doesn't work on defrost or floor/defrost.

Service engine soon light on

My 2002 pontiac has the exact same problem. I took it to my trustworthy mechanic and he told me that there is three Oxygen sensors in the emissons system. This light came on when one of them went bad. He said it is no big deal to have one go out, however if the second one goes out the car will start missing and running rough. Keep an eye on the performance of your car and if it does not dimenish then you should be alright. Fyi the oxygen sensor costs about $80 plus labor to replace it.

Smell anitfreeze when turning on the heat

A good indication that the heater core is bad, is if you get a oily film on the windshield when the defroster is on. If the headgasket is leaking, the engine should run hotter than normal,you might get oil in the radiator,you might see coolant dripping down the engine. I would start with checking out the heater core first. It is a very big job(the dash has to come out).

I have a 2002 grand am and less than a year ago had to replace cadalitic converter. The check engine light would come on once in awhile, and the car will start to bogg down. It started out as intermitent then eventually all the time. The smell may be the heating up of the converter.
