Hey Guys,
I am stumped. I have a hot start issue on my 89 EXI with only 70,000 Miles on it.

Replaced over the last month:
-Fuel Pump
-Fuel Filter
-Distributor
-Coil
-Wires
-Cap
-Rotor
-Batt terminals
-Main Relay RZ-0028

She cranks but will not catch. The shop I took it too said that when they diagnosed it had a weak spark that would come and go and that the fuel press was good.

They now think it could be a computer issue. Anything else I can try before the CPU???

Thanks for the update. I'll have to remember this one for my Prelude.

Update: EFI Coolant temp sensor was flooding out at hot start. Repalced the coolant sensor.
I have the same problem on my car. Starts up fine in the morning, but will not start when the engine's hot. Sometimes it'll start up and die after idling 2 secs.

So it's the coolant sensor that's the culprit? Is it the one that's located near the upper radiator hose/thermostat? How much does a new one cost?
