cold start problems


Vehicle Information: Year: 1980; Body Type: Targa;

I read a questions regarding cold start problems where you offered to provide a check list of potential causes for cold start problems. I will paste your response (from tech forum)for reference.I would appreciate it if you could provide me with a copy of that check list. My 3.0SC has 125,000 miles on it, runs great when warm but after sitting for a few days (or a couple of weeks) I have to crank it 7 or 8 times before it will start. It will almost catch the first few times but will die after a second or two. This is not a new problem. To get it started, I usually need to nudge the gas peddle just a bit then it will take hold and after 5 or 10 seconds of struggling, the engine will smooth out and all is fine. I have had no recent work on the car. I love this car, but would like to get in it, turn the ignition and have it immediately come to life. Am I expecting to much?Here's your answer to the earlier question...."I assume that the problem started immediately after the visit to the shop, and that it had run fine and started fine with the headers, etc. already in place. If all of that is correct, here's the best I can do. The symptoms are clearly symptoms of a lean fuel mixture. There are all kinds of things that can cause mixture problems, but coincidences are rare and my guess would be that none of the relevant components happened to fail at exactly the same time you had the work done. If you had a later SC with the steel injector lines, I would look for slightly bent lines and leaking injector seals. With the plastic lines your engine started with that usually isn't a problem. I assume the injector seals were replaced when the injectors were serviced, and that they all appear to be seated properly in their sleeves. Given all of that, I would give the shop that did the work a chance to check your intake system for air leaks before looking elsewhere for causes of the mixture problem. If no leaks are found or you want to try to do the troubleshooting yourself for some reason, let me know and I will give you a prioritized list of things to check and ways to check them."Harry Hall - PCA WebSite - 2/22/2007
