I have a 1980 280ZX it has been having issues starting. When I try to start it in the morning (like 40 degrees outside) it will crank but wont start. In the after noon (65-70 degrees) it starts fine if I give it a little gas. But this morning I tried to diagnose the problem, and there is no spark. Does anyone have any ideas what this might be? The battery, ignition module, ignition coil and voltage regulator are all new.
Howdy, I recently got my first Datsun, a 280ZX from 1979. It runs great, but it has some cold start problems -- and I mean that literally. In the morning when I try it it cranks but won't turn over; when I get home after a day of it sitting in the sun I do have to give it some gas to get it up to idle but it eventually starts fine. I checked the oil and it isn't any more viscous than it should be. I've read that the stock air pumps from this model can sometimes result in this sort of issue and that it may be worth replacing if cleaning it doesn't work, has anyone else experienced something similar? Thanks in advance, Julian
When my engine is cold I have to usually floor it before I crank and keep throttling it for a minute or two before the engine will run. Once it gets warmed up, it's runs and idles no problem. I'm thinking it's the cold start valve or thermotime switch, is there anything else I need to look at?
