#110 of 136 Fuel Pump Blown Fuse by kmarlar Jan 14, 2009 (5:29 pm)
have a 1998 Pontiac Sunfire that will blow the fuel when it is raining, snowing, etc. I have had the fuel pump checked and it is good. Dealer said that the fuel filter was clogged and replaced it. They said that it was the problem, but it has quit again(a rainy day). What could be causing this to happen, a frayed wire,a short in the wiring?
#111 of 136 What is going on in my engine by serena5 Jan 15, 2009 (9:01 am)
Jan 2nd my check engine light comes on 50 miles into a new tank of gas. Had Advance check the engine code (cylinder 2 and 3 misfire) cleared it, figured a little bit of water in my gas, so i put a cleaner or two through the tank to fix it. six hours later the car is jerking down the road one minute and fine the next (NO ENGINE LIGHT) I call the dealership and arrange to drop it off. After charging me 90 to plug it in an read the code they tell me that they aren't sure the issue but they think its the spark plugs and the wiring in the module. So i dished out the 400 to have them fix it. Not a week later the check engine light is back on for the other side. I took the car to a friend that said the coil overs and the wiring for that part of the engine are not separate from the hot parts by a firewall they are laid directly over the coils. The engine check light will come on and then ten miles later go off, randomly flickers or just stays on. Its an 04 with only 54 thousand miles on it. I technically shouldn't have had to replace the sparkplugs yet. Anyone else having this problem? Replies to this message: argus1 (Jan 15, 2009 9:16 am) slackerman (Jan 15, 2009 5:26 pm)

Replying to: serena5 (Jan 15, 2009 9:01 am) I had similar problem with my 2005.Car would begin to buck, lose power, and horrible exhaust smell. Dealer checked and said #2 misfire. - Changed ignitor - same problem a few weeks later. Another dealer said it was a wire - was OK for a month or so and then same problem. - My own mechanic worked on it - changed coil pack, even said it was computer - I bought a used one and had it programmed. All was OK for a couple of weeks - then same problem. To make a long story shorter - it turned out to be a wire intermintenly shorting against chassis. It was in a wire in wire bundle that goes to computer. You might want to check for shorting wire.
#113 of 136 I hate my car. by ciacia Jan 15, 2009 (12:16 pm)
I have a 95 Sunfire. July 08 durning a REALLY bad Michigan thunderstorm I had literally jumped a phone pole that fell across the road. I drove the car again for about another month before really getting it checked out. New tires, balljoints, rods ect, and almost $1200 later I fixed any road problems I had with it.   Now let me start with under the hood.   My interior lights, and my radio, both are really strange. When I tighen my battery or charge it for even a moment, they both turn on and work. My radio will have to be manually turned on and off. After about a week, my interior light no longer will work, and my radio needs to be manually turned on still, but is totally reset (presets, clock, ect) and now turns off with the car.   The car has stalling/starting issues. Durning the heat in the summer it would start, but I could only run it for maybe 20 mins. I couldn't let it idle, or keep turning it on and off w.o. it totally giving out on me. It would like take a min to catch to accelerate, even when im gassing it 100%, or if I was driving under about 30. Now its winter and really cold, the car has issues with wanting to start again. It doesn't drive worse or stall but it doesn't want to start. (Starter repaired three times. So far its been running agian for a week. The last two times it was within days of eachother)   My muffler, converter, and alternatior were just recently replaced. Along w. spark plugs. A few other things were replaced trying to fix the stalling problem this summer, but I'm not exactly sure what ones they were.   This week driving it was fine. Until I was reaching the stop sign and my break basically fell to the floor. Now it sounds like its pumping air, nearly will NOT work, and doesn't give any sort of stop untill it reaches the ground. My roommate found out im out of break fluid so put some in and is bleeding my lines tonight so find out if that is working. >I just dont understand how even if i was running low on the fluid, why my breaks would work just totally fine up until one moment and then totally give out?   uggh. I don't know. 19 year old girl, part time and full time jobs, supporting myself, I can't deal w. all this bs anymore with this damn car. 7 months now and I can't go two weeks w. actually having a car to drive.

Replying to: serena5 (Jan 15, 2009 9:01 am) This might not be the same thing, but my 2.4L 1996 Sunfire had similar problems with bucking and stumbling. However, the check engine light never came on. Turns out my ignition coil and spark plug boots needed to be replaced. BUT I RECEIVED TWO BAD OEM IGNITION COILS! I'm currently using an ignition coil from a junkyard while my garage works something out with AC-Delco. The moral of the story is the fixed part might be a bad part.

Replying to: rousea (Dec 28, 2008 10:22 am) Hi, I have the same problem with the headlights on a 98 sunfire. I have narrowed it down to corrosion to the main headlight wiring harness either under the front frame before the front tires or its under the battery box at the main plug. I was told by a mechanic that there is no telling how much it will cost because there is no guarantee how many hours it will take to fix it. The one thing I have noticed is if you let the problem go it will only get worse so my car is scheduled to be torn apart because now I only have one dim headlight no brights or running lights. This thing is a huge waste of money and should be recalled by the company and destroyed so no one else has this problem.
#116 of 136 battery/alternator problems by whatdidigetn2 Feb 01, 2009 (10:25 pm)
I bought a 1996 pontiac sunfire last year, the previous owner said he had replaced the motor mounts, water pump, and brakes. It ran great except for it getting hot when at idle for long periods of time, a few months later had to replace the radiator due to a major crack. Before that had to get a new rotor and all the brakes replaced. Now today when i started the car the battery light was on, went to the gas station filled the car up and got back on the road no problem other then the battery light and now brake light was on, took the highway home and the longer i drove the more the power in the car went, first the radio sputtered in and out then finally just quit, then the dash lights and head lights got dimmer til they were out but the car was still running, didn't stop at all til i pulled in my parking lot and the car died right as i put it in park. The dome light would still work just a little dimmer then usual so the battery cant be all the way dead. Anyone have any ideas? reading on here i think it's the alternator and am going to get it checked in the morning, any other ideas? any help will be greatly appreciated!!
#117 of 136 erratic temp gauge by argus1 Feb 08, 2009 (7:46 pm)
Help!! all of a sudden the temp gauge goes so far to the right - it keeps tach needle from moving. Even when car is off the temp gauge needle stays far to the right, Is is sender problem, or instrument cluster needs changing, Is true milage stored in computer so when instrument cluster with odometer is changed - the true milage changes onto the new cluster?   Thanks Replies to this message: dawnyadiesel (Feb 13, 2009 9:23 am)
#118 of 136 battery or somthing seriouse? by dohick2002 Feb 12, 2009 (8:30 am)
how offten has everyone been going through batteries on these cars. i have an '03 sunfire, has served me welll as a commuter until recently. i have had to get a jump start 6 times in the last month and a half and can garuntee that i have not left anyhing on. when i put a meter on the battery i measured .26Amps current comming out. it is possible to have a bad measurement but it also sugests that there is somthing in the electrical system that is pulling a load. I have an appointment this afternoon to get the car looked at, but are there any thoughts on the subject? and has anyone else been experiancing this problem.   hoping its just the battery. . .   Mike Replies to this message: casey60 (Feb 12, 2009 9:49 am) naddynad86 (Feb 24, 2009 9:50 am) steve194 (Apr 21, 2009 5:39 pm)

Replying to: dohick2002 (Feb 12, 2009 8:30 am) If its the original battery then replace the battery. About C$75.00 at Costco. If its a new battery you have a problem. I have a 2002 and had to replace the battery 6 months ago as well.
