The map sensor would probably throw a code if it were bad. they do sometimes get gunked up and dont read the right air volume. you might want to check the fuel rail and injectors to make sure they aren't going bad on you. also fuel pump and filter and fuel line, you could have a kink.

Check the throttle sensor and MASS air flow sensor. Throttle sensor cheap check first. MASS nice penny.

SOURCE: 1988 honda accord lxi- will start if I spray

Clogged fuel injectors. Or, starting fluid is basically high octane fuel which doesnt require efficient or hot spark plugs to start, so maybe you need to look at your ignition system, especially your spark plugs, wires, or cup rotors -- perhaps they are not delivering a hot enough spark for regular fuel. While at it, also check the ignition timing. In other words, clean your injectors and get a tune up. Finally, make sure the throttle body is not leaking air.

SOURCE: 1991 honda accord. will not start on its own.

If the car dies after it runs for a minute then I would suspect either the fuel pump or the fuel pump relay. Turn the key on but not to run, you should hear the fuel pump for about 5 seconds, you could also check the fuel injector rail for fuel pressure, just put a rag over the shrader valve before depressing it, if the pump is making pressure it will squirt out. If still no luck pull the fuel pump relay and jumper the hot wires and listen for the pump.

About the only thing you didn't mention was the starter itself. You could have it tested. But before that, try to see if you have power on the small wire to starter solenoid on the starter, when key is held in cranking position. Pull the small wire off and check for power with a multimeter or a testlight while someone holds the key in crank. This is the signal wire from ignition switch that closes the elec. contacts inside solenoid so the starter gets full power from the battery to spin. (This wire also is in the circuit with the clutch switch and the starter relay.) If you have power on this wire in crank, it is very likely the starter is bad. If there is no power, check that circuit out. It is losing power somewhere from switch to starter solenoid. Good luck.

1995 Honda Accord cranks but won't start unless I step on the gas pedal repeatedly. There are times though that it will start fine with no problems, such as, when the car is warmed up. Can you please...

You may want to check the map sensor. Honda accord uses map sensors. To check it, turn the car to on position and apply vacuum. The voltage in one of the three pins should change as vacuum is applied. Note: do not apply too much vacuum because it can be damaged that way. Out of the three pins there is 1. the power source (usually 5 volts) this do not change. 2. Ground (this is usually a floating ground so do not ground it to any metal parts of the body or you can end up with a computer damage. 3. Is the output signal (this is the signal that should change in respect to ground). Without vacuum applied it is usually around 2 volts, and as vacuum is applied it goes down. A word of caution. Use digital multimeter to do testing and never jump anything or short any wire in anyway so be careful.
