I was backing out of the driveway and it was like someone turned off the key on me. Now I can't get the engine started at all. Turns over, but wont start. I can hear the fuel pump run and tried shooting starting fluid in, still won't even sputter. Replaced the cam position sensor and the engine temp sensor. Still won't start. What now. Replace computer? Yikes! $$$$

Take two wires off the coil that are right next to each other have someone crank it over while ur watching for a spark jumping from coil tower to tower. Let me know if u have spark. Also do u mean the crank shaft postion sensor there is no cam sensor. Let me know.

I took off two spark plug wires next to each other and saw no spark while the car was being turned over. It was the crank sensor I replaced, right above the starter. ALso it is the 4 door coupe, the model might be SC2, not SL2. I'm a Saturn newbie.

The crank sensor is below the starter with a yellow wire and a purple wire going to it. Get a ohm meter and check both the old crank sensor and the new one they should be around 800 ohms. Make sure all ur fuses are good especially ur eis 10 amp mini fuse that's ur ignition fuse. In ur underhood junction fuse box. Let me know what u find.

All of the fuses are good (I made sure to check the EIS one under the hood). The old crank sensor was 850 ohms, the new one was 950 (checked it before I installed it yesterday). I figured the old one was still good but switched them anyways. Any more ideas before I spring for a computer module?

Ok. Replaced the igntion maodule which the coils are mounted on. The car tried to start. A little nudging on the petal and it finally fired up, ran like crap for about 5 seconds, then smoothed out nicely.

Problem solved. Thanks for your help!

Glad to hear u got it figured out the engine computers don't go bad very often so I didn't want to see u replace the computer before u tested everything else to pin it down to a computer or something else. Glad to hear u got it figured out that's what were here for if u have any future questions or concerns feel free to ask away. Thanks for using 2carpros.
