Okay... I have my opinion as to what just happened, but I'm gonna keep it to myself for now. I don't want people just blindly agreeing with me. I'd like to get some opinions as to what just happened, free from my influence. The car in question is a 1990 Accord with a 2.2L engine.

So, anyway... here I was, Christmas morning, driving along without a care in the world. Then, all of a sudden, my car quits running. It was like someone just turned the key off while I was cruising down the road. I coasted into a parking spot and tried to figure out what was what. The first thing I did was try to restart it. It tries to run... it just can't. It'll fire, but it immediately dies. Stays running for literally one second. No matter how many times I try, it'll start immediately - just like it always has - then die the second I disengage the starter.

Funny thing, though... if I don't release the key (i.e. keep the starter engaged), it'll stay running until I do. But, the second I release the key, she dies.

What do you think, guys?! If you can help me out here, I'll be forever in your debt.

Merry Christmas to me, huh?!

I'm thinking bad ignition switch. From the sound of it you're getting fuel, air and spark *only* when the ignition is set to "start" but not "on"...

Before anybody says anything, it's not the battery and it's not the alternator. Something is cutting either the fuel supply or the fire when I disengage the starter (i.e. turn the key from Start to Run). I'm leaning towards the former. I don't think this is a fire problem. I think it's a fuel issue. So, here are some ideas:

Fuel Pump? Maybe. But, it starts up just fine. It just won't stay running for more than a second unless I keep the starter engaged.

Throttle Position Sensor? Maybe. I think this is more likely than the fuel pump. I also get terrible fuel economy (less than 20 mpg in an Accord) and a very subtle idle surge at highway speeds. The tach will creep up about 150 rpm, then the car will hiccup when it drops back down. It's annoying.

Ignition Switch? Maybe. If it's bad, then the car might think I shut it off, which would definitely cut the fuel supply.

What do you guys think? There are three ideas... I'm open to any others you might have.

A guy told me to try something... he said, "Start the car, but don't let go of the key once it starts. Turn it back slowly until the starter disengages. If the car runs, the switch is bad."

So, I did it... it happened just like he said. The car stays running as long as I hold the key just ahead of the Run position. Once I return the key to the Run position, it dies.

Looks like my ignition switch is bad...

...does anybody argue this idea?

Conceptually it's possible, while I can't provide you with any specific information since I don't have wiring diagram, you can validate this theory by providing a jumper to connect 12VDC to the wire in the ignition switch wiring harness which provides 12VDC to the rest of the car after the switch has been released from cranking, i.e. the second position of the on/accessory/run/start positions.
