i have a 97 accord coupe that is having a starting problem,maybe a tech guru can help me out here. i read all the posts on the no-start problem and have been going over all the typical things relating to the problem.car has had the timing belt and waterpump replaced.i recently cleaned the iac valve,throttle body,replaced the tps switch,battery,ground cable,terminals,coil,cap,rotor,plugs,and fuel filter.car had the up/down idle problem and cleaning the iac seemed to help.the main problem is the car will start and run perfect (slightly high idle 1k rpm).i'll drive the car around and get it up to temp still no problem.i'll shut it off and immediately restart -still no problem.let it sit maybe an hour and it will just crank and seem like its trying to fire,just sputtering.i smell fuel when this is happening.and have also tested for spark while this is happening and i have spark.i checked the computer for codes -no codes or engine light.i talked to a tech and he suggested possibly a leaking injector flooding the engine.i have yet to pull the main relay if i can find it,but i hear the fuel pump working and have fuel at the rail.any help would be appreciated.
