My 94 Accord EX 4 cyl 5 sp has occasional starting issues. Mostly it starts fine but every once in awhile it cranks fine but won't start. I initially thought it might be vapor lock so I released tank pressure without effect & after next successful start I filled the tank up - don't know if vapor lock still occurs in these fuel injected engines. I'm still wondering about fuel system - filter or pump but haven't done any real problem diagnosis on it yet. Any ideas out there on a good trouble shooting approach or problem guesses? Thanks.
