280z dislikes warm starts


Recommended Posts

So my 280z runs like a top and has just done two trips to Oregon and back from California but it has an issue it will start cold no problem but it absolutely hates starting warm. Like if I go and get gas when I go to start it back it will sputter or simply refuse to start all together. I am thinking the fuel rail is getting too hot and is vapor locking it but I am not too sure what to do to rectify this problem.

That is exactly what is happening.

 

I installed the factory cooling fan system from a 280zx turbo and it immediately went away......but it's ugly!!

 

I got the timer from a Z31 300zx 84 to 86..........it was inside the B pillar near the driver's hip.

 

Through the course of installation, I found the wiring diagram was incorrect so I corrected it such that it now works.
