Last Summer, I had a heck of a time trying to figure out an intermiten igniton problem. After getting the engine warmed up, like driving to a store and then coming back after 20min or so, I could not get it started. Only after lifting the hood and waiting 10-20 min is when it would then start agian. I had fuel, but no spark everytime this would happen. I then R&R'd all the important sensors, the coil and distributor cap.
Well needless to say either because of weather or that I found the particular sensor I haven't had a problem until yesterday. Well I did the standard diagnosis, unplug CPS, check fuel. No start. Then I started looking at the vacuum lines on the manifold and of course some are dry rotted and need replacing. Well I removed the line that goes to the MAP, and it started, It sounded kinda rough until I put the vacuum line back in, but kept running and got me home. This morning it got me to work just fine, and this evening I'll be replacing some lines.
I don't know if this is an actual ? or just sharing information about HO diagnosis. If anyone else has any ideas, because this problem is a royal PITA. TIA
