Re: Chevrolet Corsica fuel problem
Make sure the spark plugs are set right and clean then given the cars age i would say the catalytic converter needs replaced. keep a clean air filter in it also your brand of oils and filter are important don`t settle for just any oil the best two that i`vie tested is GTX castrol oil and valvoline syntec high mileage. oil filter recommended FRAM

As with any no start issue, you need to figure out if you are dealing with a no fuel or no spark problem to proceed. The pump could have failed, or the filter in the tank could be plugged up. I would make sure it has spark at the plugs and then check fuel pressure with a gauge.
It sounds like the gas control lever under the hood may be sticking a little and not retracting fully to idle.Open your hood and have someone start your car.When they give it some gas you should see the actuator move which has a cable attached,probably located at the end of the fuel injectors on the driver side.It should be pretty noticeable as about the only moving mechanism when the gas pedal is pushed.Usually pushing the gas pedal makes the lever move toward the driver.Once you have found it,push down on it in the opposite direction as giving gas to see if the revs decrease back closer to idle.If it does,WD-40 on the hinge where it pivots may help.Spray it,rev it a couple times and check.Even if it works on the first try,do it a couple more times.If this does not work,please reply back and I will get an auto link to see what you posted. Good luck! Greg
Coils and wires are the most likely culprits as they never get replaced hardly ever. You cant really test a coil, you can check for resistance on the plug wires but that doesnt tell you if the insulation is bad on them.
You may have gotten a gas can full of water ( not literally ) but there was plenty of water to make a difference. Check the fuel filter I would completely drain the fuel tank and blow out the fuel lines. Is this a multi port or throttle body injection ( you may may want to clean your injectors ) ANY WAY CHANGING YOUR FILTER SHOULD SOLVE YOUR PROBLEM GOOD LUCK !!
