Car has been sitting for 6 years, only has 55,000 miles on it. Fuel pump was all gummed up so replaced that with new. Changed oil and put new oil filter on, changed spark plugs, install new serpentine belt. Checked fuses and they seem fine. Went to start car and it won't turn over. It has spark but possibly not getting fuel to fuel rail. Made the mistake of pumping the pedal to help it get started and flooded the darn thing. Looked online for a possible solution and found to reeplace the CPS and or coolant sensor. Purchased those last night but have not had a chance to install yet. If that doesn't work, any idea where I turn next.
Flooded? Im pretty sure it's fuel injected, so pumping the gas does nothing- the computer controls the injectors based on other parameters.
If fuel ssystem is gummed up, you need to clean it all out, including the tank.
You say it won't turn over, does that mean the engine won't crank at all? If so then the pistons could be seized, could be a bad starter/relay. If it cranks then try spraying some starter fluid in the intake while cranking to see if it tries to run. If it stumbles and tries, then it sounds like just a fuel problem.
You have spark at the plugs ..thats something
spray stay you mug
into the throttle body see if the motor will cough
tank needs draining and have fresh fuel
fuel pump has a filter and fuel relay
crack the fuel line connection to the rail to see if there is fuel reaching the rail and correct pressure
if sitting 6 years.. not being run regularly
do a compression test
lifters may be stuck
rings may have lost tension

not enough compression needs around 150 each those are known for head gasket problems

i bet the coolant temp sensor is bad,,,when the sensor cracks coolant leaks into and wrecks it and then the coolant leaks thru the sensor and into the harness,,,and this causes the car to dump too much fuel because the computer is seeing a temp that is not real and therefore the air fuel mixture is off and flooding the car,,,typical issue,replace the coolant temp sensor and then harness,,like $75 for both at saturn,,do not by the aftermarket ones,yes the cost less but they are junk and will not work either,,,also i bet if you put the gas pedal to the floor or pump it when this happens i bet the car starts and smokes when it does,,,,saturn redsigned the sensor for this reason,it was plastic and they made it brass so now it can not crack and leak,the aftermarket ones are still plastic junk
