ok i have a b16a crx and every morning or when it sits for a while it will crank over for a bit and on occasion sound like the starter just locks up for a second then starts up or it will crank over for a bit then start but idle really low then pick up untill normal idle. If its been warmed up it starts up no problem. sometimes it sounds like fuel pump doesnt come on at first could this be fuel relay maybe? its throwing no codes and runs great just worried its going to get worst to the point it just wont start.

 

To far advance on the base ignition timing will give you a hard start cold and a locking up as well juring cranking, maybe check the valve timing as well?

 

will do asap thanks

 

is the base timing 16 degrees btdc? jdm and usdm the same?

 

12 +/-2 Not sure about the diffrence but all I have is Can/UA specs
