TahoeDawgZ71, yes the reverse buzzer does work when this problem occurs. The only time I haven't had the buzzer operate is when I reset the computer per the instructions on this site, and it began buzzing again after a short period. The MCOR is something I need to investigate, but I do hear a micro-switch operate when I activate the foot pedal. Whether the cart moves at that point or not, well, that's another thing!

Have you ever experienced a micro-switch that would 'click' and then for a random amount of time, from one second to up to a minute (or not move that day!), prevent a cart from moving? That is what I am experiencing, and just to make life interesting this morning I went out and the cart behaved just fine. This problem occurs whether I have just charged the batteries or driven the cart a few miles. The one common thread is it occurs after the foot pedal has gone from unpressed to on, and position doesn't seem to be a factor.
Agree with sternk13 on all points. Only thing I will add is that sometimes when this occurs on my cart if I keep the pedal depressed the cart will eventually move. This problem also seems to occur more often if I park uphill, almost like the cart cannot generate enough torque to move. I do have a CC dealer about 30 miles from here and may take it over one day and have them put the tester on it.

I too have noticed that if I hold the pedal down after a while the cart will usually take off. Yesterday I went for a drive and had to hold the pedal down for about five minutes (!) before the solenoid finally clicked and the cart took off.

I'll have a look at the MCOR. I'm not sure where the nearest dealer is since I live out on a farm near a small town.

This is something I would try, if I were experiencing this, to test the MCOR. I would jack up the rear wheels so when they turn, the cart wouldn't take off. I would unplug the 2 wire plug that plugs into the MCOR. It is the micro switch plug. Leave the other plug plugged into the MCOR. Put the cart in forward. Key on, and use a wood block to hold the gas pedal down. Make a little U shaped jumper wire and jump across the 2 wire plug. If the wheels turn every time you jump the plug then the MCOR micro switch is bad. If you still get the delay in starting then the problem is further down the line. This would at least test the micro switch in the MCOR. Just make sure the rear end is properly jacked up. I do have the IQ plug-in tester but they seem to be year specific. My 2002 tester wouldn't work in some 2003's that I tried to use it on. They also don't tell all. That start-stop problem I talked about earlier didn't show up on the IQ tester at all. Diagnostic setting said "no faults detected". Even though the cart stopped. After saying all this, I'm going to say that I question whether the problem is the micro switch. Usually they just go bad and stop working. But I have found that just about the time you think you see a standard, it isn't one any more.

Good idea.... About the IQ test equipment... There's only two variations of IQDM machines and they're both compatible with all years. I guess you just had a dirty connection on your 03s

This thread got me thinking so I decided to cut into a couple bad MCOR's I saved from past repairs. After cutting off the back side of the MCOR I found a single micro switch and a small circuit board inside. The circuit board has no electronic parts on it. (resistors, diodes,etc). When the foot pedal splined shaft to the MCOR turns, it simply slides two sets of 4 little metal fingers across 2 black surfaces that gradually increase the voltage to the output wires of the MCOR. I would imagine that these things fail when the little metal fingers no longer make proper contact with the black surfaces. Because of wear. The thing that makes me laugh the most is that these MCOR's could be easily built so they could be repaired for a fraction of the cost of buying a new one. The micro switch can't be more than a few bucks and the circuit board shouldn't be more than about $10. It is also perfectly possible to have a removeable back panel instead of glueing the whole thing together. Profit margins on these buggers must be gigantic!!!

Yep, that's why they're sealed.

Don't know if this has any bearing on the problem we are experiencing but prior to playing golf all this past weekend I was cleaning up the cart and remembered a post about placing a tie wrap around the post on the bottom of the accelerator. Just for shicks and grins I decided to try it. Played 90+ holes since Friday and did not experience the hesitation once. Go figure.
