Grand AM :: 1993 Pontiac V6 - Cooling Fan Start Running As Soon As Car Is Started
Oct 25, 2013
I have a 93 pontiac grand am 3300 V6 with auto tranny. My problem is cooling fan starts running as soon as car is started. AC not on or defrost. In turn doesn't allow engine to reach normal operating temp. I have replaced both the ect sensor & gauge sending unit. I've noticed there's a red light with temp symbol in lower left hand corner of instrument panel that stays on & won't allow ac to come on. Also if I unplug fan relay & allow engine to come up to operating temp the light hoes off. Until the engine drops below 200degrees then it'll come on again. It has just the one fan & I have ruled out the fan relay cause I replaced with a new one. Also, looking for wiring diagram for the rest of relays on firewall & as to what they control.

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.

I have a 98 Grand am with the 2.5 and recently noticed first that the a/c compressor wasn't coming on. It had freon added recently and did okay for a few days,then no compressor coming on again. (It still has freon) Then I noticed that the engine cooling fan was running as long as the engine is running on cold or hot engine with heat controls off (I know the compressor runs when on on defrost position as well as a/c). I thought the 2 problems may be related? I found 5 relays at R/F strut tower and the 3rd relay cut off the fan,so I swapped some of the relays, but made no difference.The fan only quits when I turn the engine off, and I can't get the a/c compressor to come. I don't if I have 2 seperate problems or not. Could it be the PCM?

Drove 28mi out to dinner and when leaving after, she wouldn't start. Took it to work in the morning, and it ran fine prior to that. It was 15degrees outside, added heat to the gastank thinking the fuel line was frozen. Tryed to fire on, but it would only idle briefly surging while doing so and die, like not enough gas. It did start after I held the key down during this surging process grinding the starter also, should have driven home, but I shut it off like a idiot, as a result, had to tow home. Noticed TCS OFF light was lite up while it was running, then I shut it off, TCS OFF LIGHT went away when I turned key back on to attempt a 2nd restart. After i did that, it wouldn't fire on again. Towed to my house, I do not hear the fuel pump trying to kick on when i turn on the key. Fuel system is dry. Cranked over next day and definitely no gas in the lines. Bled the fuel system, no fuel shot out. Have checked the fuse box and the one under the hood too. Replaced the fuel pump relay but still no go just (this blows)...

We have a 2003 Grand Prix. For the last few years it has this intermittent problem. Sometimes it just won't start and occasionally it will die while stopped at an intersection. I did some digging online and found out what the likely culprit is, but do not know how to fix it. I already spent a lot of money for a mechanic to claim he fixed it, but didn't.
According to online sources [URL] .... the security system TDM is at fault. It stops recognizing the VATS transponder in the key and thinks the car is being stolen. So, it cuts the connection to the engine. Clearly a dangerous situation if you are driving. My 17 yo daughter recently got stuck in a very busy intersection.
The temporary fix is to turn the key to the on position without turning the engine, wait 10 minutes then try starting the car. This is supposed to reset the security system. Now this is starting to not work. Someone suggested bypassing or modulating the TDM signal by adding in a resistor. I really don't feel equipped to do this though. Another solution is to buy a bypass module.

I have a 93 Ford Explorer, manual transmission. About a month ago it intermittently started running very rough. I does this wether the weather is rainy or not. The engine has done this when it just started up, cold, and when it's been fully warmed up. I have been able to drive it, but it has been quite a challenge. When running, there is a very noticeable noxious exhaust smell. The check engine light has come on some of the time. When the eec codes were checked it only revealed 522, the car wasn't in park or neutral when running the test.
I have tried clearing and rerunning this test several times, yet 522 still shows up. No other fault codes. Don't know how this would cause engine to perform so bad. The fuel tank has been near full when it happened so I believe the gas to be good/ no water. The engine has a lot of mileage on it, over 200K, so I'm not sure if something inside could be malfunctioning, but don't know how to check. The car will run for days very smoothly before this happens again. I have changed plugs, wires and the pcv valve and it still occurs. It's like the engine is hitting on one cylinder when it happens.

I bought a 2003 Pontiac Grand Am a month ago, I have already replaced the power steering pump, the water pump, plugs and wires, new battery. It was running fine I drove it last night, but the radio has said loc since I bought it. Then today I got in it and tried to start it and it won't start. It turns over like it is going to start but doesn't. I tried the 10 minute reset thing. That didn't work.

2002 Grand Prix, 3.8L na motor, 187K miles. It was running perfectly until 4 days ago. initially, odd gauge stuff and flashing air bag light, then very, very slight engine skip with the tach gauge flipping around. 2 days ago, harder than usual starts ( a couple of seconds cranking instead of instant starts ), 1 day go, longer cranking in the morning, worse stuttering at highway speed. Afternoon, very hard start, stuttering right away, and then it would hardly start and quit after seconds. Gauges flipping and relays buzzing under the dash.
I had it towed home. Moving the key to run I didn't hear the fuel pump running. Checked the pressure at the rail, zero pressure. I removed the relay and jumped it to run the pump at high pressure. Fuel pump ran, pressure was 50-60lbs. Reinserted the relay, tried to start it and no change. I couldn't hear the pump running. Removed the relay and jumped the pump again, left it running and tried starting the car. Also no start.
I'm thinking it may have something to do with the ignition switch, PK3 system, BCM or PCM although I'm not sure which way to go with testing. I'm going to re-check the fuel pump and then start taking ignition switch out.

Cooling 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.

I have a 1996 Pontiac grand am gt. It started over heat and bog down. I put more dex-cool in it but its not cooling down. After doing so, I stopped, got out and checked underneath. It was pouring fast. I checked all hoes to and from the reservoir...all good. I was told it could be the lower intake manifold gasket...true/false...

I have a 1993 Grand Prix. Just wondering, how to disable the auto locking on this Pontiac Grand Prix? The switch stopped working and I would just like to disable it rather than try to figure out why the switch does not have power.

I have a 2004 Pontiac Grand Am, it has a V6. I live in AZ, so right now its like 110 outside and my ac will work fine when i am driving but when i stop at a stoplight it starts blowing hot but when I start driving again it takes about a minute and then it will blow cold again and it does this same thing at every stoplight, but if the car is just idling in my yard with the ac on it blows cold it doesn't do this, I thought maybe it was low on freon and bought a can of ac pro with a gauge and when i checked the pressure it went into the red so it says not to add any, and contact a mechanic. But what may be wrong with it first, I replaced the ac compressor 2 years ago. A couple of days ago I replaced all the radiator hoses and the radiator and the coolant tank and of course added the right amount of dexcool. The car is not getting hot, the problem is just with the ac ,

I have no clue why my 2002 Pontiac Grand Am SE uses a lot of fuel. I Don't drive often, perhaps twice per week, sometimes not at all.

I have a 2001 Pontiac Grand Am se that was overheating and I found out that it had a blown headgasket and the fuel pump was going out. So I changed the head gasket and fuel pump. After all that I proceeded to start it but all it did was crank and not start. I did Research on the passlock and bypassed it and the security light stopped blinking and went away but all it did was crank and not start. Could the timing be off and cause it not to start? It gets correct ammout of fuel and correct compression? Also the timing chain is loose enough for me to jiggle it.

When I turn the car off the key only goes to acc. If I wait a few minutes I can hear a clicking sound coming from the steering column I think. Then I can turn it off all the way.Whats causing this? and how do i fix it. My car is a pontiac Grand Prix 2002.

We have a 1997 Pontiac Grand Am 2.4L. Recently it has begun to shut off while it is being driven. We will have to pull over and wait X amount of time before it will restart. An interesting addition to this is that it only happens when the weather is hot. If it is a cold or wet day, this will not happen and the car will run perfectly.
We have tried several things on this car to try to fix this problem. We have replaced Computer
Fuel pump
CPS or Hall sensor
Water pump
Control module
Cam sensor
Both coils
Throttle Sensor
Thermostat
New Radiator

I have a 2003 Pontiac Gran Am GT 3.4 and i just noticed yesterday when i start my car now it sounds like i have one lifter that is fairly loud, it goes away about 10 minutes after its running. It did it for the first time when we were at the inlaws yesterday, after a few hours of sitting i went out to warm the car up and heard it. Then in the evening after sitting for a few hours i went out to warm it up and did it again. is it possible to be dirty and need something ran though the engine like seafoam?
