All Part Groups Won't Start When starting Not applicable
Q: It starts sometimes but not other times. It usually won't start about 6 hours after I have used the car. It usually will start in the morning but not the afternoon. Once I get the car running the engine runs beautifully. The engine does turn over so it is not the battery.
I can sit there with the key turned in the ignition and all I ever hear is the started turning over. Sometimes I've continued to do this for about five minutes (holding the key down for no longer than 8 seconds at a time) and the engine has finally started, but usually I have to let it sit for a couple of hours again before I can try again.
I'm fairly sure gas gets to the cylinders, because I sometimes smell gas in the engine while I'm trying to start it.
I just recently got high performance spark plugs. and have checked the plug wires, which are intact. Do I need to get high performance spark plug wires as well?
Help me please! I need my car!
A: My first guess would be to check the coolant temperature sensor... ensure it is signalling the computer of changes to temperature.
If it is out of range, the computer won't provide enough fuel to start a not-cold, but not-warm engine....
Also try cycling the key on for 2 seconds, and off for 2, and on for 2, without cranking the engine over...
Try that 4 or 5 times before cranking to start, and if this works, the fuel pressure may be bleeding back to the tank..... Ed
Heating / Cooling System Malfunction Happens always Always
Q: The cooling fans continue running from a cold start to warm up. Is a sensor possible for this problem? It's not overheating.
Also, it acts like its not running properly on a cold start; after warmup it's fine.... other then the fans running.
Any help would be appreciated. I'm hoping for something simple. Thank you.
A: Collant temp sensor triggers the fans in case of overheating. If sensor thinks that the engine is overheating, it will provide LESS fuel and turn on fan to help. Ed
