hey guys, i'm new to this forum and it has lots of info to learn but my question is i have a 95 civic vtec and the engine ceased so i did a motor swap (1st timer).i put a b18 with the original harness from the b16.everything fit well but my problem is when the car is cold it don't want to start up,but if i keep trying eventually it will start. i have to keep on cranking it over until it sort of want to start but after like ten minuets it will start then it will be fine.when the car is warmed up it starts fine.CAN ANYBODY KNOW WHAT THIS CAN BE OR WHAT I DID WRONG OR DO I NEED TO AD SOMETHING ELSE.HELP HELP

P.S I ALSO CHANGED THE COMPUTER.

i'm pulling the codes and getting 6 fast flashing lights,i believe thats = #6 ect (engine coolant temp).can any tell me where is this sensor located and will that help the problem......thanks

its on the side of the head near the the thermastat. Does your temp gauge register anything? Also the engine coolant temp sensor is the main sensor you ecu looks at for starting, to calc the amount of fuel delivered. Should be the cheapest sensor under the hood to buy
