fuel & exhaust My 94 accord won't start even after changing lots of parts?My mechanic did following to fix my starting problem(usually have problem when in the morning)1)changed ignition switch(2 months ago)(2) Electronic wiring diagram(2 months ago)(3) changed distribution assembly(2 months ago)(4) changed "some kind of" relay(might be a master relay)(3 months ago)(5) timing belt changed about 2 years ago(about 30,000 miles ago)My battery and starter is fine.It's been starting ok for a month but doesn't start again this morning..What else could it be besides the things mentioned?it sounds almost start but doesn't fully start.

Might be that the distributer is bad agian or you have gotten some moisture in it. Try opening it up and spraying some WD-40 or PB Blaster in it and try to start it. If this does not work, i would look to the coil and have it checked.

I had a 94 prelude that did the same thing. we replaced the ignition switch and it started right up. Then, it died about a month later. We changed the ign. switch again and it started right up. Maybe a short somewhere?

I my 94 accord was doing the same thing we replaced the Master Relay and that fixed it. Might also be that the fuel pump and fuel filter is shot.

It could be a problem with the ECT sensor (Engine Coolent Temperature) as this is one of the main control sensors for the PGMFi system. If the plugs are black it may be over fueling. You need to check the fuel pressure also it should be between 2.5 to 3 bar. You need to check the power supply to the Injectors and the Distributor when the fault occurs. The black yellow wire to the Distributor is the power supply. Test the injectors any wire should be around battery voltage on both pluged in. If no power to the injectors check to main PGMFi relay again, no power to the Distributor check the ignition switch again. Good luck!
