I recently bought a 98 accord LX 2.3 automatic, changed the oil, thermostat ,coolant and brakes, runs great, 200,000 miles..put about 700 miles on it since I got it,..then one day I parked it for 5 minutes,go to start it and it won’t start..so I waited a minute then tried again, starts up,drove it about 2 blocks then died while driving,pulled it over ,waited a minute ,started it up and it ran for days no problem, then it happened again, same thing,won’t start ,wait a minute then it starts… so NOW it doesn’t start at all..here’s what’s going on:•I pulled the plugs,they are fuel fouled ,i even took them out just the day before to check them and they looked good,they are autolites,ugh,but looked good.
•checked battery (12.40)
• replaced coil
• replaced crankshaft positioning sensor
• checked ignition switch,it doesn’t seem to be the problem (I may be wrong)
•I pulled and inspected the main relay,I will test it tomorrow but I don’t think it’s the main relay if I have fuel fouled plugs..means fuel is getting to injectors,I also hear the fuel pump prime when I turn ignition on
I have heard about main relay issues,i have a new one coming,just in case.
• I checked spark by grounding a spark plug, I think it has a weak spark, it was yellowish during ignition.
•there is a slight smell of unburned fuel from the tailpipe.
• after replacing all that ,it cranks and almost wants to start but doesn’t..

I know I need new plugs(NGK)
wires
cap & rotor

is there anything else I can do or try,..it ran on Monday,no start Tuesday..i would appreciate any insights as this would be my first Honda,won’t be my last but I want to keep this one for a while!! lol
