Check that you got the timing marks right. If you recheck the timing belt work & it's o/k then start with the basics, Is the fuel pump running when you turn thekey? whats the fuel pressure? Is fuel getting to engine? do you have spark?
I replaced water pump had to remove timing belt installed water pump installed timing belt car won't start.
you will replace the timing chain when mornig cold start becomes noisy Normally it will last the life of the engine, and is replaced when the engine is overhauled.
The timing "chain"will start rattling at around the 100k to 110k mark. This is when it should be replaced
2 possibles: 1:The engine was not timed correctly when the timing belt was replaced 2: An ignition lead left disconnected when the timing belt cover was replaced.
probably put the timing belt out of sync
According to Honda's website the standard Civic models did not start using a timing chain until 2006 with the exception of the SI models which were a different engine and have always had a timing chain. But PRIOR to 2006 all the other civic models had timing belts (which have to be replaced to be replaced periodically).
Check to see if your vehicle jumped timing.
The timing or crankcase sensor needs to be checked and most likely replaced.
It is not timed correctly.
check timing chain/belt to see if it is broken
Well, if it ran smooth for the 20 seconds then timing has nothing to do with it. Sounds like a fuel shortage. Have the pump checked, and also the filter.
Check your timing, if it goes out of time a small margin it won't start properly or not at all.
