it has fuel, fire, timing is good, what would cause a car to loose compression on every cylinder at the same time?????

here is the story.......

i have a 95 ls block with a 2000 b16 head in my 92 hatch. the car was running pretty good when i was running the ls injectors in it but it seemed like it was starving for fuel up around vtec. so i put a set of prelude injectors 345cc on it with the restistor box. i am running the hondata s300 with the stock JDM P72 map right now.

anyway i drove this thing all day and it really seemed like it was running quite a bit better...... until this last time i drove it. i was just going down the highway at a normal speed and it just died all of a sudden.

i stopped and tried to start it back up but it sounded like no compression at all. when i got it home and checked it the compression guage wont move on any cylinder. 0,0,0,0.

so my question is: it has fuel, fire, timing is good, what would cause a car to loose compression on every cylinder at the same time?????

 

recheck your timing again, its good, do a leak down test because it sounds like you have bent valves..

 

maybe you snapped a timing belt

 

timing belt jumped!!! or snapped...
