After sitting, hard to start, seems not to be getting fuel. you can spray starting fluid and it starts, must run at higher than normal idle for a few minutes, then will idle normally.

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

Doesn't seem to be getting fuel when i start it , doesn't run. then after sitting for a while it sometimes starts and run for just a few minutes, whats the problem?

dosent seem to get fuel is different than not getting fuel.
spray some starter fuel in it when it wont run and see if it starts and dies.
it sounds like a ignition module .
but it very well may be a fuel pump is weak and intermitent.

99 Taurus wont start unless primed. Fuel pump is working

Check/Change Fuel Filter(s), PVC Valve & Emission Hoses
and/or
Gas that sits too long won't fire easily that's why we have to add winterize to our lawn mowers!
Try filling the tank with some high grade fuel cleaner additive. This stuff is like rocket fuel (about $10).
Also add a can of dry gas as you may have a lot of water and water vapor in your system!
Get a couple more cans of starter fluid too. (I always needed at least two to get my diesel running for summer)
Keep spraying and starting (It always took me at least a full can sometimes 2)
When it starts keep the gas pedal down and rev high for a good 5-10 minutes then see if it will idle.
If it still stumbles and falls consider adding another can of fuel system cleaner and/or dry gas.
Don't drain the tank as this usually just makes it worse by letting the bottom sludge stir up.
Never let your gas tank get too low as this will foul up your fuel system and always add fuel cleaner after every oil change (a must for fuel injection and cat. converter care)

Good Luck!

Engine will not idle and run when starting in cold weather

Have a mechanic take a look at your throttle position sensor and engine idle sensor. Make him manually adjust them as opposed to just putting in new ones. It may require that you have to have a higher idle than normal. Your underlying cause is going to be that I am sure you have a lot of miles on your engine.

1991 Buick Regal, auto trans, 3.8L engine, problem; upon starting it would idle at higher than normal rpm and would not drop back down even when warmed up.

the problem may be a buildup of carbon or fuel varnish deposits in the idle speed control valve (also called the idle air control valve or IAC valve). The cure for this condition is to clean the valve with some aerosol throttle cleaner or engine top cleaner. disconnect the air ductwork from the throttle body. Start the car and run at about 1500 rpms spray the cleaner directly into the throat of the throttle body. Turn off the engine and let sit for a few minutes. Then repeat the process a cpouple of times. if that does not work, you can remove the IAC and clen it by spraying into the two holes on the underside of the valve.If not, then you need to replace the valve.

OPERATION The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the throttle body on. This valve allows air to bypass the throttle plate. The amount of air is determined by the Powertrain Control Module (PCM) and controlled by a duty cycle signal. Fig. 1: Cleanable IAC valve — 5.0L engine version shown, others similar After sitting, hard to start - 88484g22.gif
Fig. 2: Non-cleanable IAC valve — 5.0L engine version shown, others similar
TESTING OBD-I System

Make sure the ignition key is OFF.
Disconnect the air control valve.
Use an ohmmeter to measure the resistance between the terminals of the valve solenoid. NOTE: Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR pin and the negative lead on the ISC pin.
If the resistance is not 7–13 ohms, replace the air control valve.

I'm sorry, but on my screen it shows an x in a box for each illustration. I am not sure what you see at your end, though.

But, if there is an 'icon' where a picture belongs, try to click on it.

Sometimes it works and sometimes it doesn't from feeback that I've gotten back.

Sometimes it's hard to upload all of the information from my online resource to Fixya.com.

But, I tried.
Duane Wong Aug 01, 2010

You could try to buy the Chilton's or Hayne's manual for it which would have illustrations in it.
