My wife drove her 2000 Honda civic hx home from work. 2 hrs later she goes back out to it. It cranks for a couple seconds then dies. If you try to give it gas it dies quicker. So far i have put on a new fuel filter, fuel pump, injectors, new distributor, new plugs, cleaned out the throttle body, and replaced the map sensor. Any ideas on what else it could be?

 

Welcome in,looks like you covered most everything,timing belt possibly.

 

You should have someone do a pressure test.

 

Yea,compression test would tell if you might have a blown head gasket.
