1993 Honda Accord 4 cyl Front Wheel Drive Automatic 152500 miles
I have a '93 Accord that within the first 5 miles I drive down the highway it dies. At first when it started doing this I thought it might be the fuel pump. But after a couple weeks I have come to other conclusions. It will do this roughly 4-8 times and then it will run fine the rest of the 15-30 miles I have to drive. Most generally when it dies it will not start for 5-20 minutes. It has gotten worst the last couple days. I have talked to a couple local mechanics who have narrowed it down to either a fuel relay or an ignitor in the distributor. I have not been able to check to see if there is fire when it does this do to being by myself. Does anyone have any ideas or comments on what I could do to diagnose without paying an arm and leg?
If the engine's condition is in tip top shape-do below to determine if its fuel or spark problem that's if its cranking over and refuses to start
Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

Since you have narrowed it down to a fuel relay or distributor, my suggestion is to check the main relay. Known to be very unreliable and intermittently don't work due to poor circuit board.
