VEHICLE CONTINUES TO DIE GOING DOWN THE H

1993 Honda Accord

Electrical problem
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?
Thank You!

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

Hi don31blackshirt,

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.
