My parents owne a 1983 280ZX, l28 engine with 73,000 with a strange problem. The car in the morning will start normally but suddenly die after 2 to 5 minutes. It acts as if the ignition has been turned off. It will restart after about 10 minutes and will run perfectly for the rest of the day. They have taken it to a number of mechanics who have failed to diagnosis the problem.
Has anyone else experienced this type of problem?
Any hints on how to approach this?

Thank,

Steve Cunningham

I would take a look at the Cold Start Injector. This would be one of the things that only comes into play first thing in the morning when you start the car.

Take a look at the thermostat housing.
There are one or two sensors threaded into
the housing and one of them is called
a 'THERMOTIME SWITCH'. this sensor
is the on / off switch for the
cold start valve. Take out a couple of
spark plugs next time and check to
see if thay are soaked with gas.
You need a 24mm deep socket to
remove the sensor.

I own a 1982 280zx and had the same problem sometimes it would die while driving. Someone on another site recommended that I replace the Ingnition Module. Its a small black box the size of a match box located on the side of the distributor. It takes a small phillips to remove it. The wires just pull out but be careful not to rip them out. I was racking my brains trying to figure this one out. And I haven't had problems yet. Good Luck! Alvin
