Replaced the spark plugs and wires on my 2001 Saturn SL1 Sedan and the service engine keeps coming on took ht e car to auto zone sam trouble code as before Misfire on Cylinde 1

The plugs are wet so its not a fuel problem its a spark/ignition problem. Check the plugs connected to the correct wires. remove one plug and with its wire still on it tie it down to a metal part on the engine. Turn the engine over and look for a spark on the plug, is there one?

What fault codes are in memory?

sc1 means saturn coupe with a single overhead cam engine sl1 means saturn sedan with a single overhead cam engine same engine and same parts for both these cars

Hello: You Can try disconnecting the battery for 20 seconds but if you haven't corrected the problem the light will come back on. You need to go to auto zone or advance auto and find out what code you have so you can repair it. They can also clear the code.

NGK spark plugs, Saturn part number for the SOHC is 21025102 and for the DOHC is 21025103.

Hello: The number one injector could be stuck open. to check you will have to remove fuel rail with injectors attached, energize fuel pump with key off and see if #1 injector drips/sprays fuel. YOU COULD ALSO SWAP #1 AND #2 injector and see if the misfire goes to #2 cylinder.

TAKE VECHICLE TO AUTO ZONE THEY WILL SCAN IT FREE AND TELL YOU TROUBLE CODE YOU ARE GETTING.

P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.

Check the starter.

It was the coolant temperature sensor. It was telling the car that the coolant was always cold, therefore when starting a warm engine it was being flooded. $$$
