1995 Saturn SL2 Car wont turn over

When u say it won't turn off do u mean it cranks but won't start if so does it pop sputter etc?Or are u saying it won't even crank over?

So what ur saying is when u were done with ur valve cover and spark plug wires u went to start the car and the engine wouldn't turn over?Can u hear the starter click no click?Do the dash lights come on with the key on?Do the dash lights dim or go out when u try to start it.

It sounds like ur spark plug wires might be incorrectly wired when ur looking at the engine starting from ur left that's number one then number two and so on look at ur emissions label it shows which cyclinder goes to which coil post make sure there right let me know what u find.

Well miss placed wires was my best guess did u check to see if u cracked any plugs or if all the plugs were gapped at.040"?If it ran before it's got to be something u did when u made ur repairs.
Louie

So now it doesn't turn over?Before u said it did can u hear the starter click or anything?
Louie

Well I would make sure the battery cables are clean and tight also u could have just killed the battery try charging it or jump starting it to see if it turns over.

Glad to hear u got it all figured out glad I could help u.
