1995 Buick LeSabre 3.8 Liter Wont start unless I push down on gas pedal like it wants more gas, Why? Runs OK when running


Possibly a bad or dirty Idle Air Control motor. The engine computer controls the operation of this motor to control idle speed. A pintle on the motor extends and retracts, according to signal from the computer. The pintle controls an air passage below it to give or take away air during idle -when the throttle shaft is closed, no air will get into the engine through the throttle body except through the idle air passage . The IAC motor or valve is on the throttle body, with a 4 wire connector. Take it off and look for carbon or coking deposits around the valve's pintle, and in the air passage beneath it. With the idle valve off, plug the connector back on it, then watch the pintle as the key is turned to on. If there is no movement whatsoever, the motor is probably bad.

I have also heard that a bad coolant temperature sensor can cause such a hard start. If the computer does not know the engine is cold, it won't put enough gas into the cylinders for easy starts. The engine needs more gas to start and run when cold.

It won't shift 1-2 or 2-3 or both unless you let off? If it is just 1-2 it might be a band adjustment, but I'll bet you have a plugged governor solenoid screen also.

89 dodge shadow. hard start. normal idle cold, fast idle warm. sometimes it wont start until i hear fuel pump activate.


Hello,
The car may be hard to start because it may need a normal tune-up. If the spark plugs are pretty used, they will slowly stop burning as much fuel because the spark slowly gets lesser and lesser. On a cold day the fuel is harder to ignite with a small amount of spark.
Normal idle when its cold means that your cars idle is probably too high. If you lower the idle, the choke on a cold day will keep the idle a little higher until the motor warms and then it will kick back off. If the idle is too high, it will run very rich, smothering itself with fuel, and causing the idle to stay low. When the car warms, its creating better spark when its warm, and with the idle being too high its running at a fast idle.
The car wont start sometimes can be the cause of a few things. If the ground is bad on the fuel pump, it wont make a good connection sometimes for when you turn the key on, the fuel pump dont pump the fuel to the engine. Another one can be that your accessory switch can be loose going to the fuel pump. I think its your ground though. Good luck! Hope this helps.
Have a nice day. -Steve
