93 saturn sc1

What engine does it have 2.2 l , 2.4 l Does it have good compression ? Timing belt or timing chain ? Jumped time . What model saturn ?

if the timing chain is broken it will sound different like there is no compression also this is an interference engine i think meaning the valves will hit the pistons if the timing is not correct,like in a broken chain or belt.you should check to see if you have spark at the plugs and if the motor is getting fuel.if not then each system will have to be checked out depending which is not working.

it has a busted belt or chain you can remove the timing cover on top or sometimes there is a plug on the cover you can remove to see if the cam is rotating i hope this is not a interferance engine kang kang kang may be vavles bending in that case you will have to pull the head and fix the bent val.

All you should have to do is squeeze the plastic clips together, you may need a pliers. Another thing that helps is spray some WD-40 in there and rotate the filter on the line a little.

The 2001 Saturn SL1 has a timing chain which shouldn't need maintenance for the life of the engine or 200,000 miles typically. hope this helps

need to have a shop fix it asap.if the chain breaks or skips timing your entire could possibly need to be replaced.replacing a serpentine belt tensioner is fairly cheap and easy

Something inside the engine is starting to come apart. What exactlly??.....It's hard to say until you start tearing down the engine. Was there any noticable problems with the chain/belt or the sprockets? If you would like to dig into the engine, let me know and I can give you some simpler checks to do. Hope this helps.

Does it crank the engine ? If not take a look at the starter connections and the starter.Replace the starter if nessesary.
Ok, now that you got the most common problems out of the way, you should check for spark at the spark plugs. Remove a spark plug and attached to the wire. Get a good pair of rubber gloves and put the thread of the plug to ground and crank the engine. The spark plug should spark a bluish spark. If it has an orange spark the spark plug or wire may be bad. if it does spark fairly good.

Check the fuel pump. if it has an electric fuel pump you should hear it when you turn the switch to on. It is a whirring sound. if you can't hear it. the Pump is bad or the shutoff valve turned off the fuel system. Check it to see if the button is up. If it is then the valve clicked off. Press it down. If it is down and there is no fuel the fuel pump is bad.

If it is a mechanical pump, take off the hose to the carb if it does have one. crank the engine . It should pump gas right away.

If it does have spark or fuel to the sytem, then it is a sensor or other problem.You will have to get a trouble code for it. to narrow everything down.

Check the timing belt or chain to see if it is still good and tight. If it is not your timing belt or chain skipped or cut off. you will have to replace it.

I hope you can get some help from this info . good luck

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

the timing belt on a 1.9l saturn is located under the valve cover on the left (passenger) side of the engine. this is the same on a DOHC or SOHC saturn motor. it is driven by the crank shaft and turns the cam shaft(s) in order to move the valves in the correct order. you should expect to pay at least 40 dollars for the belt itself. as far as installation... check you local service center.
