I have a 90 Honda Accord that is my daily driver it has run perfect for as long as i have had it. But last weekend i headed out of town in it and it died. Now when the car is cold it will crank for a while then start but as soon as it gets warm it dies and cannot be restarted til it cools back down. I have already replaced the ignition control module and the coil with no luck. Any suggestions would be greatly appreciated.

Check for fuel pressure at the rail.

When it will not start, what is missing---fuel or spark.

I believe it is the Main relay
