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

2003 yukon xl turns over fine wont start.


Someone will need to figure out if you are lacking fuel to the injectors or spark to the plugs to proceed.
You say the pump is fine, have you checked the fuel pressure, and do you know if the injectors are getting voltage and ground pulse from the computer ?

Our 2003 Saturn L200 turns over, but won't start...like it's not getting gas. This just started happening and only after we've already driven it that day. The first time it happened was...


Check fuel pressure at the injector rail. If good, suspect crankshaft position sensor--when it fails to start, check for sparks by pulling an ignition wire off the coils and holding it close to the coil with an insulated tool while someone cranks the engine. If no sparks, replace the sensor.

I have a 98 s-10 it wont start it has 40 to 45 pounds of pressure & its firing getting gas but wont run i pulled the fuel pump relay n it try to run i sprayed it with start fluid it hits but if i put...


If this truck has the 4.3L vortec motor it will not start with 40-45 PSI fuel Pressure.Thius engine requires approx. 56 PSI fuel pressure or it will not start. The fuel pump more than likely needs to be replaced this is a common problem with the 4.3L vortec engine.Change the fuel pump and your problems will be solved.

I have a 94 Caprice 4.3 v8 and the past week it will run fine the acts like it's not getting enough fuel back fire real loud and die and it takes bout 10 mins before it will start again then when it does...


not starving fuel but "flooding out" and putting unburnt fuel in the exhaust system which ignites and damages mufflers and cat converters
check for excessive fuel pressure or bad /leaking injectors

97 Saturn sl2. Won't start after it gets warm. If you drive it for 15-20 minutes and try to restart it will not engage the starter. Wait a couple hours and it will start fine


It is your engine coolant temp sensor (ECTS). 99.9%. the saturn made them with a plastic tip, so they crack over time. A replacement should be about 15 bucks and not too hard to replace. You'll notice your engine temp gauge not working (always cold).

I don't know much about cars, but here's what happens. When your car is cold, the fuel runs rich. Your broken sensor is always reading that the engine is cold, but when it is warm, it runs too rich and floods your engine, not allowing it to start. When your engine is actually cold, everything is fine.

Car wont start


The problems could be:
1- Check your spark plug. -see any fire come out- " dirty or clean"
2- check the crankshaft sensor - ( you can clean it)
3- check to see the gas go to the fuel injector/caburator line
* If your car use caburator- you may have gas over flood in the cabu. like your father said. IF there is no gas flood- try to spay the cabuator start bottle that you can buy any where in car part store.
I have all three different problems above since I am driven. Good luck.

Cant get enough fuel pressure to run properly


May have to run in line fuel pressure gauge to determine if the fuel is losing pressure and causing this fault or wether you need to look else where like constant injector pulse,air flow meter,faulty distributor etc.
