Saturn wont start

Put the engine no.1 piston on its compressiion stroke/TDC and align the cam and crank to its marking as indicated in the repair manual

What liter engine is this?

Those are the easiest engines to time they habe colored links on the timing chain dowl holes you can line up with a drill bit. Do you still need timing marks diagram?

There you go sorry it took so long I lost track of your question. Let me know what you find.

If you pop off the valve cover you can check the timing that way you dont have to remove the front cover. Check the timing and let me know what you find. Also those cars are known for bad coolant temp sensor and those cause no starts. Also the connectors to them get corroded as well and have to be replaced. Let me know what you find and we will go from there.

Its below the upper radiator hose screwed into the head with two wires going to it a yellow wire and a black wire. Also inspect the inside of the connector if the terminals are green or blue instead of silver you will have to replace the connector also. The sensors are only like 10-11.

Your welcome keep me posted.

The valve cover not being on all the way wouldnt cause it not to run. The vacuum line was hooked up to the pcv correct?Also did you check the timing?If so what did you find?Also how did you check the coolant temp sensor?With a multimeter?Did you inspect the connector?

Yes the the vacuum hose goes from the intake manifold to the pcv. You cant visually inspect a coolant temp sensor sometimes you can see that the plastic sensor tipped cracked. You have to use a multimeter to ohms check them and compare the ohms reading to temp and see if its within range. Its really common for them to go bad I have replaced hundreds of bad ones.I have gone thru 3 sensors so far on my 1999 saturn SL2 that I have owned for 5yrs now. The sensors are only 10-11 so if you want to try one there not expensive. Otherwise get a multimeter and lets check the old one. As far as the connector I was talking about the one going to the coolant temp sensor. The inside of connector will have the terminals they should have silver terminals if there blue or green then you will habe to replace the connector. Because that would mean you have corroded terminals. Also have you checked your fuel pressure?I would do that also just to elimnate a fuel pressure problem.

Also have you checked to make sure you didnt mix up your spark plug wire order?To check the fuel pressure you would go to a auto parts store like auto zone rent a fuel pressure gauge. Then screw the hose onto the nipple on the fuel line going to the injector rail. Then turn the key on to the run position wait a few seconds then repeat and see what the gauge reads.
