I thought the posts on this subject would help me solve this problem. They did not, although the posts provided me with some info. I think I will check the valve and see if it needs cleaning or replaced. BTW: It got almost 60 degrees today here today and my 87 ZXT started right up with no problems. From all the related posts, it would seem my problem could be more than just the cold start valve. Any updates on this subject would be appreciated. I could use that scematic that Jason mentioned on my ZX. Can you download me a copy. Thanks ( I am a long time driver of both 280s and 300x. )
BTW: My fog lights are both not working. I took the bulbs with their attached rubber boots out and checked them on my battery. Neither of them lit up. Where can I buy a set of replacements or does anybody on this forum have a set I could obtain cheap? Thanks !!

 

Mass meter systems omit the extra inject/ cold start valve
