1990 Honda Accord LX, 4Dr, At, 4 Cylinders, 2.2L, 272,296 miles. I changed to a new car battery 6 months ago. About 8 weeks after, car hard to start when engine is hot. I changed after market BECK/ARNLEY Main Relay (Fuel Injector Relay). Then, everything back to normal for about 2 weeks. Then, car needs to crank 2-3 times before it can be started. It gradually goes bad and hard to start doesn't matter engine is cold or hot (need to crank 4-6 times) for the next 2.5 months. Get Main Relay warranty replaced. The 1st week, car needs to crank 1-2 times to start engine. Then, it goes back to before warranty replaced situation and needs to crank many times (at least 5-7 times) before engine can be started. Sometimes, it can't be started. I checked spark plugs. All plugs create spark, but seem weak spark to me. Spark wire is 10K~15K ohm (spec is less than 25K ohm). Changed distributor cap, but not rotor (it looks good and just wire brushed to clean it). Car can be started after 2-5 cranks. Better than without changing distributor cap which almost can't be started. Spark plugs are old, but looks good (just wire brushed to clean). I changed back to my previous old plugs for just testing and car has the same issue, hard to start. This roots down to ignition coil and igniter (ICM, Ignition Control Modul). The ignition coil check against to spec. and looks OK. I tried to check ICM, but Haynes manual doesn't seem very clear. The wire color doesn't match to my car's wire and picture doesn't clear to which terminals to check. Anyone has any idea of how to check ICM? Any idea of what could be the real issue causing hard to start? I am not planning to keep this car long and don't want to throw money to replace old parts which still work.

Does anyone know where to get the correct readings or range for your cars Live Data readings on OBD2scanner. I Have several readings regarding sensors I need to compare to.Or at least know what range is normal. Finding this Thanks
