So my Z was having that cutout problem when it would warm up. I could not figure it out for the life of me either. I changed fuel pressure regulator, fuel pump, filter... Couldn't figure it out. Did a full tune up as well. After more research it was looing like the ign control mod. I ended up buying a new distributor (don't have soldering capabilities right now) and that fixed the problem! It doesn't cut out anymore! I just need to reset the timing and idle. Maybe check out my iac. I figure out why my mileage sucks. I've cleaned the connectors. I'm thinking of getting a new chts. Had to let you guys now the Z is rolling again! Have a good one guys!

when you say you z cut out what do you mean?

My car is hard to start when engine is warmed up, it may take like 3 or 4 tries to start again.
Before the car would not start at all. so i swapped in a used one, now it starts but i have the hard to start when hot symptom.
Haynes manual says air filter or clogged fuel tank vent lines.

The car would run fine while cold but after it warmed up It would just flat out die. No sputter, no hesitation. Sometimes it would start right back up, sometimes it would struggle and take a few times. Didn't matter if the gas cap was on or off. Sometimes on these when the ign control module on these are starting to go bad when they heat up they will just cut out. One of the things you could do is test the dwell on it when it's heated up and see if that will help. It may be a clogged line but it's hard to tell man. I chased this problem for 6 months.

Hey, I've been having the same problem with my '80 280zx 2+2, and I was wondering if you happened to replace the Ign Control mod or if you replaced the distributor only. Those two parts are seperate and I can't really afford both right now, so an idea of which one first would help a lot.

Well the mechanic had no soldering abilities and I didn't have time. We replaced the whole distributor.

lww

I'm not sure how much you described these symptoms earlier since I didn't see the post but that is a classic example of a failing ignition control module. When they start to fail they will work intermittently when hot. There's no soldering necessary to replace the ignition control module. It's just a couple of spade connectors. Even if it weren't a soldering iron can be had for less than $10 and $2 worth of solder...

Noted. Well ****. lol That was an expensive repair bill.

Nice, thanks a lot. I'm new to this site, and somewhat new to working on my own car. Second car I've owned and second Z I've owned so I guess this is the right place. Haha
