94 Honda EX hard starting / false starts when cold, Ok hot
 

HI, car started having problems a few weeks ago when weather cooled. Cranks great. ( fast, Battery strong) Will crank then false start ( run for a second then shut down) after maybe 15 - 20 cranks most esp toward the end runs longer before dying. When it does start, engine runs good, no misfire, roughness. You can put in gear and go. Talked to local Honda dealer, they did not want to help unless I had the shop look at it. Is there a cold start injector on it? air temp sensor gone haywire? Ideas? Thanks
