Ok I have tried on other sights to get some answers to this issue with no success so it was time to step up to the big leagues to get the answer. I have a 97 Honda prelude auto. Tranny is fine no issues their. I am having a nagging issue though. My car has a real issue with hard start and on occasion no start, the problem goes like this . First start up of day car starts fine no issue , if I park for like minutes and then start up up again it will still start fine. Now if I leave it parked for 15min or more after useing the car it will crank but not turn over ride away and kinda stumbles before it starts. Sometimes when the weather is warmer outside it will not start at all for at least two key turns. If the car is left parked over night or at least a few hrs it will usually start up fine but any time between that time it hard starts.
Things I have changed
Plugs/wires
Cap/rotor
Coil
Coolant sensors
Timing belt/water pump
Charged battery
Main relay(aftermarket cheap one)
Nothing has helped, also just recently got the catalytic convertor code so I know something is going on. Please guys help a brother out I'm lost.

 

im having the same problem, check to see if u gettin fuel...im about to check my fuel injectors and the fuel filter

 

Thats what I was leaning towards now since sometimes I can smell fuel whats the best way to check your injectors, lmk what you find and ill keep you posted on my findings.

 

somebody told me with a ohm meter to check the fuel injecters

 

Hmm I have one did they tell you how thats interesting

 

I googled and found how to test it unplug the injector harness set ohm meter to 2k, then hook it up to contact points on injector they should read 15 maybe a little more or less but if its under 12 then thiers most likely a issue with that injector.

 

Ok update is checked injectors with multimeter all were reading good. So I took out plugs and looked down in the wells. Cylinders 1&2 look clean, 3&4 have a lot of carbon build up and so did the plugs so I'm leaning towards leaking injectors on 3&4. Got injectors in the mail. Will update

 

Fixed this issue the whole time (7months) it was a leaky fuel injector oring the fuel would leak very slow, thus loosing pressure slowly making the car not have pressure as I would try to start it. I decided to change all the orings for preventive messures
