Default No Compression

Anyone might know why I lost almost all compression? Going down the highway about 130 on juice pulling strong then car shuts down won't start. Plugs are fouled checked all fuses, maf ok. Compression is zero in 3 cyl ,40 psi in one. Did a wet one in one of the cyl with zero and no change. l

Any broken valve springs? Pull the covers and check for this or any bent valve stems keeping the valve(s) open. Open valves=0 compression. HTH

Yea tommorow gonna pull the covers and see if the valves are opening and closing. Next is pull the heads. Worst case is rings but it just seems strange that they all go at the same time

How many miles on the engine? I'd suspect a timing chain.

Didn't mention that I didn't check the other four cyl compression cause the engine was cranking so fast with plugs in I didn't think ther was much comp in any cyl.

Could be a broken retainer or keeper(s) too. Anything keeping those puppies open. I'm betting on valve vs. rings. Let us know.

Most likely ring lands broken / piece of a piston gone. "on the juice..." Sorry.
