Re: Intermittant starting problem
It's probably your MASTER RELAY. I had the same problem and so did my friend. I searched the net for an answer and always came up with master relay. I took mine out, resoldered it and it hasn't done it again. That was over a year ago. The Master Relay is right under the dash on the drivers side (on my '90 anyway). You just take it out, open the cover, resolder all the connections at the top of it and it's good as new. Apparently the solder they used in Malaysia or whatever was sub-par and when it gets old the solder disconnects after it gets hot. When it cools (usually 5-15 minutes) it will work again. Go to this link! You will thank me. It is an extremly easy repair and works great. I was sceptical but it worked when Honda dealers, mechanics and everyone else couldn't figure it out. Don't know why more people don't know about this. Everyone I know that has a 90-93 Honda Accord has this same problem. Usually only does it when the car has been driven a short distance.

Sounds like the fuel pump may be intermittant...which unfortunately is located inside the fuel tank...there is a service port on the engine that allows you to test the pressure of the pump...it is located on the fuel rail that feeds the fuel injectors...this would be a good place to start....other possible problems with the fuel system are the fuel pressure regulator, fuel injectors, tps sensor, and possible but unlikely the PCM(computer)...A way to test the pump without tools would be to bang on the fuel tank and see if the problem ceases..if the pump starts working, then it is intermittant and I would suggest replacing as it may fail again...and quite possibly, when youre in a bad place or area
My 92 Bird with the 3.1 did the same thing after it sat for about 2 months. The car had aways started right away before. I had to jump start it and I thought it would never start.Same as yours after it started. Seem to get better after I ran it awhile. It was getting good spark and was getting fuel. I checked fuel pressure, it seemed to be within specs.then it started to sputter and the pressure dropped to almost nothing. Seems that the fuel pump was going bad, but still would pump enough fuel at times to run. When the car was parked the fuel pressure would bleed off, and when I tried to start it the pump had trouble pumping enough fuel to pressure the system.Long story short! Replace the fuel pump, and filter.....
You need to get the schematic / wiring diagram . There is a junction block in the center console where the wiring is routed to the entire car. The contact on the power wire to the pump gets burned /dirty and becomes intermittant . It needs to be cleaned .This happened to me twice.
It could be an ignition related issue or fuel.
When it doesn't start does it crank, do you have the ignition lights?
The most common problem of intermittant no star probems is the crank sensor on the front of the engine, they can break down over a period of time and fail when warm. if not then I would fit a fuel pressure guage to the car and run it. Then see what the reading is when warm. If it is nothing (should be 38-40) then I would replace the fuel pump relay.
The fuel pumps typically don't fail intermittantly, they just fail!
