starting problem after run to full temp

Asked by Oct 13, 2013 at 08:51 PM about the Datsun 280Z

Question type: Maintenance & Repair

I have a 1977 208z with fuel injection and after it has been driven and is up to full temp
then turned off and I try to re-start it in say 15 minutes, it acts like a vapor lock. CHUG A
LUG CHUG A LUG for about 30 sec before smoothing out. Does a 77 280z have a
Cylinder Head Sensor? I was told to try replacing it but I'm not sure it has one. I know
there's a Coolent Sensor. Could that cause the problem?

I too have a 77 280Z I have that same problem. It's really irritating! I just had my engine professionally rebuilt and everything that went back was new with the exception of a fan clutch. I bought one as suggested. I also went to the Nissan dealer and got an OEM thermostat. It was also suggested to get a fan shroud. None of that made any difference because she stays cool when in motion, it's sitting at long lights or in traffic that brings the temp up. I think from here on out I am going to try an electric fan in hopes that it works better than the fan clutch and the diminished RPM's when at idle. Good luck with yours too, sincerely.
