So you’re having a no start condition? I am assuming it is a crank no start condition. You don’t want to go on assumptions, find out if it has fuel. The first thing I would do is hook up a fuel pressure gague and measure the fuel pressure. Compare this reading with the specs. I think on those older model Cavaliers (Before 2000, there is no quick connect test port and you must disconnect the fuel line going into the fuel rail and tee into it.

and if i have good fuel pressure up too 40 pounds?
Well if you have normal fuel pressure I would check the operation of your fuel injectors. Although this is a slim chance considering all four injectors would need to be malfunctioning in order for a no start condition. The engine will typically start and run really crappy if one or two injectors isn’t working.
If you have good spark on all your plugs, then I will bet your fuel pressure will not be up to specs.
EDIT: Yes it would be helpful to know how you did your testing of spark.
Quoted From dreamer2355:
First off, is there a check engine light?
How are you testing for spark and/or fuel?
Screw driver and jumping a spark to engine block. ALSO i sprayed carby cleaner into it and it tried to fire.

I cleared all DTC codes the other day and 2 of them revolved around crank. Which leads me to think it can be that but then it wouldnt have spark? a few others where throttle body problems but i think thats when i unplugged it and set some codes off.
Hi mettintc,
Has the check engine light come back on, and if so, what are the code(s) please? Keep us posted.I agree with everyone above that advocates getting those codes if you have them. I would also recommend you pull the plugs, you may have fuel but too much so if the plugs are wet with fuel you should leave them out and let them and the cylinders air out before trying to start it again. If the plugs are dry then you might check the fuel pressure just to see if it’s in the correct range for your engine. Your much better off testing and gathering evidence than you are just replacing parts. Good luck.
