Cool 1993 Honda Del Sol Startup Problem
1993 Honda Del Sol S will not start after shutting off engine and letting it sit for a few minutes. I have replaced the main relay but it did not help. If I turn the key to on without cranking and let it sit for approximately a minute, you will here a click and then (I believe) the fuel pump kick's on. At that point it will crank up. Anyone have suggestions on what I can check next?

RE: 1993 Honda Del Sol Startup Problem
I would be looking for why that fuel pump relay takes a full minute to bring up the fuel pump. If you can locate that relay and put a meter or test light in it maybe you can figure out if the voltage is low or it has a bad connection. After all the car is 18 years old

OTOH, it may not be the fuel pump relay so other things to look at would be fuel pressure or loss of spark during that same time frame.

Let us know what you find and maybe we can help you work this out.

I kept hearing the click sound from under the center console of my Honda Del Sol. I pulled out the console today. There is a (Looks like a selnoid switch) switch mounted in front of the the shifter. If I turn the key to the on position and leave it on for a minute the switch will engage. Then the engine will crank. There is also a plastic lever that attaches to the shifter. I do not have a car manual so I do not know what this does. Is this part going bad?
I have also checked the electrical plans that I could find, but no mention of a fuel pump relay. If you do a search it refers to Main Relay.

If this is an automatic transmisson that solenoid may be to prevent you from shifting out of park without stepping on the brake but hard to say from here.

You keep using the term crank or crank up, which usually means hearing the starter motor. Does the engine actually start and run at any point? Can you drive the car without any other issues once it's running?

When I turn the key switch (ignition)to the on position the switch behind the shifter will engage. You can see it pull in an make contact. It will not disengage if I continue on turning the key to the cranking position. The engine will keep turn over but not start. If I leave the the key in the on position for a minute (plus or minus) the switch behind the shifter (being engaged) will disengage to the position before I put the key into the ignition switch. Once the switch behind the shifter control engages and disengages you can hear the fuel pump cut on. The car will crank up and run. It run normal. I drive it where ever I need at this point. I just do not want to go to far from home in the Del Sol and stop somewhere and it not crank up again. Thanks for your interest and continued help.
