1998 Dodge Neon no run sohc 2.0l neon

If there no compression, you have to have valves stuck open. Have you removed the valve cover to check?

yes have removed valve cover don,t see any thing rong pulled fuel pump relay was going to put oil in each cylinder with no compresion recheck compresion hopeing compresion will come back never had only good compresson on one cylinder if it is stuck valves how do i free them up?

either the timing has jumped, the valves are stuck open, or you have holes in the tops of 3 pistons. As far as fixing valves that are stuck open, it really is based on the cause. Are you certain the timing is correct and with the valve cover off, you don't see any sticking valves?

im thinking exaust valves bent in cylinder 1 3 4 with plugs out when i put compressed air down number 1 cylinder it alows air to come back though 3 and 4 cylinder so don,t thank theres hole in pistons whan car came to me timming belt was off had snaped bolt for tensioner cam some one has been in here before no need to take cam bolt loose replaced with used asembley also replaced inner timing cover and outer cover replaced timing belt made sure marks lined up my next step is to pull head and hoop i can find good head from bone yard

I agree. I feel that is what happened. Let me know what you find when you remove the head.
