Question about 1998 Saturn SL
I replaced the fuel pump, O2 sensor and plugs in a 1998 saturn and it starts right up with the fuel rail off but when its on I have to hold the pedal to the floor to start

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

The following are malfunctions that could cause a rich condition:
^ Fuel pressure too high. Perform fuel pressure test.
^ Leaking fuel injector(s). - Perform pressure leak down test.
^ Vacuum leak around the MAP sensor grommet.
^ Oxygen sensor contamination.
^ Restricted exhaust or air intake.
^ Fuel Vapor Canister saturated with fuel.
IMPORTANT: If the front oxygen reading voltage is above 600 mV and the rear HO2S is above 600 mV all the time, the O2 sensors are probably not

the coolant temp sensor is located on the right side of the cyl head its small under by the upper rad hose 13mm socket removes it after u take the small connector of,make sure the car is cold coolant will come out when u remove it,,,,check the connector too for corrosion,by only saturn sensor the cheap autozone and aftermarket ones dont read right and give you the same problem as the old bad one
