hi Scotty, I have a question. I have a 2000 Honda Civic, when it was running I was experiencing bad throttle response, so I checked the spark plugs, they were fine, started up the car and then it shut off, and then it became a crank no start issue. It does have fuel pressure, there is spark, but I don't have any compression in any of the cylinders, the timing belt looks fine it hasn't come off although I think it might have skipped a tooth but I don't think it could cause the compression issue in all of the cylinders. what do you think might be the issue because I have no clue. Appreciate your response.

no compression is probably a timing belt problem. IF all cylinders have no compression it pretty much would have to be that if it ran before, then stopped running

You think there might be a valve issue, piston rings, gasket issue?
