Sounds like the idle speed motor is not working or very dirty throttle body.
You would have to remove the black plastic hose on top of the throttle body and get a cleaner(throttle body cleaner or carb. cleaner) and spray it down into the opening.
If you have a hard time starting because of the liquid in the throttle body, try holding down the gas pedal while starting.

My 2004 cavalier will not turn over without excessive pumping of the gas pedal. Battery, starter and everything else seems to be fine. Is it the pump or something else?


Try this next time you start it. Turn the key to the run position, do not start the engine. Wait 3-5 seconds and turn the key off. Turn the key right back to the on position and wait for 3-5 seconds. Turn the key off. Repeat the above one more time. Now try to start. If it starts right up you have a fuel supply problem. Either the fuel pump is bleeding off or the fuel pressure regulator is leaking. Pumping the pedal is doing nothing besides buying time for the fuel system to pressurize. Post an engine size and I'll help you locate the fuel pressure regulator. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

is the engine grounded to the body? if so, you may have a key issue that's only going to get worse. your key is coded, black square ignition key right? $75.00 dealer only. sorry but it sounds like that's your problem. almost like a valet key. only works for short time and if you keep using it, it will blow the fuel pump$379.00 please do more research! hope this helps,and merry christmas from me and mine,to you and yours.

1991 Jeep Wrangler has been sitting in a garage for 3 years. It starts and shuts right off. I spray ether in it and it starts then shuts back off again. It seems as though I am not getting fuel. What do...


im asuming it was running fine when it was garaged? if so, then the first thing you need to do is to drain the fuel tank and flush the fuel lines. when gas gets old, it simply wont ignite. and over that time, it thickens into almost a syrup. so you need to drain and clean the fuel tank, fuel lines, and replace the fuel filter. im not sure if that year jeep is carbureted or fuel injected, but if it has a carb., then that will definitely need to be cleaned. or for fuel injection, use a good fuel injector cleaner mixed with your new gas. once it starts, it wlil run a bit rough, but once the old fuel gets burned out of the system, it should gradually improve.

99 cherokee sport starts hard after sitting over night or 3 to 4 hrs. starts right away if key is turned on and off2to3 times represurizing the system


Could be related to the fuel system. What have you replaced or checked so far. I would look at the battery and the charging system. Also look for a fuel leak, pump pressure, and the vehicles maintenance/repair history.

Jeep starts hard.


Sounds like the fuel pump is going bad. There is an anti-drainback valve inside which may have failed.
Have a more competent shop check it out. (or , just repalce pump)
