I have a 2000 Saturn I won at an vehicle auction, I got it to start and got it home running very rough by pressing the gas pedal all the way to the floor. I tried starting it the other day after tunning it up and now it wont even turn over, the engine just keeps cranking. I've replaced the spark plugs, spark wires, oil and oil filter, battery, cleaned the throttle body and the Intake manifold so far but still no luck. Even tried a jump start and it won't turn over. The OBDII sensor reads no error codes. One more thing is the inspection said that previous customer put to much oil in it before me but I had it running, it was running roughly but still I had it working at one point.

You said you got it started by holding the gas pedal all the way to the floor. Have you checked the coolant temp sensor yet?Also check the connector going to it if the connector is corroded it need's to be replaced. The sensor is only 10 and it's real common for them to go bad they cause starting issue's over heating all kind's of thing's.

I replaced the temp sensor for the coolant it was pretty messed up and looked burnt. I tried starting the car and it still just cranks without turning over. I even tried to jump start it and nothing. Everything works it wants to start but just doesnt.

Did you inspect the connector going to the sensor for being corroded?Also what color was the wire's going to the sensor you changed?Is the security light on solid or flashing when it doesn't start?Also have you tried holding the gas pedal all the way to the floor while starting the car maybe it's flooded?I would also get a noid light and see if your getting injector pulse.I would also check and see what the fuel pressure was.

The report said the there was 0 psi on all 4 cylinders. That it spikes 30*0*30*0 doesn not hold. Whatever that means. There is a possibility of a blown head gasket or timing chain. They also said the coolant smelled like it was mixed with gas.

Sound's like a timing chain issue and possible some bent valve's.

Theres no bent valvues but there seems to be either a blown head gasket or a timming chain problem, the car has about 123k miles on it do u think its worth fixing?

First of all thank you so much for the donation. If you have such low compression on all the cylinder's I would say it was something to do with the valve's or the timing chain jumped time. You asked if it was worth fixing if you the do the work it will cut the cost's way down. What did yo pay for it at the auction where you bought it?

I paid 600 for the car, 80 for the battery, 120 for the new radioator, about 80 for spark wires n plugs, 30 on oil n filters, and the 12 for the temp sensor. Ive heard it better to just replace the engine with a used one if I have to change the timing chain, but if its simple enough I can probably to it myself.

So you are ahead of the game still. So have you taken off the head off yet?The timing chain's are easy to change though.
