Need a little help with a non-starter

Car wounldn't start. Then did. I'd like to know why since I don't want to be away from home when it happens next time.

I cranked it several times and it would crank great (nea battery) but wouldn't actually run. Didn't even stumble as if it was getting any fuel and trying to start. I did this like 6 times. I had my foot on the clutch.

I came in the house and did some research. I read up on the DME and the fuel pump. I went out and turned the key partway to listen for the fuel pump ( I heard nothing) so I cranked it to look for the tach bounce - fired right up. I did not have my foot on the clutch.

I shut her down and tried to start with the clutch depressed. Started again. Shut her down again because I used the allloted time to work on it.

It's about 40 degrees outside. The car is new to me, so we don't have a history together. I have had it about a month, but probably only drove 150 miles. Some questions:

1. Could this be a DME-type problem?
2. Where do I listen for the fuel pump? The back I assume. Does it run when the key is only partway turned? What does it sound like...similar to the 911? Or do I need to jump the connections to hear it run?
3. I guess there is no clutch safety switch in these things, huh?
4. What else might it be?

Many thanks.

Garage
Fuel pump only runs while cranking and after the engine starts. You can lean out of the car head toward the ground, crank the car a few turns then stop. You should hear the fuel pump (rear of passengers tire) for about a half second after you stop the cranking.

Most non starts turns out to be the DME/fuel pump relay. The ignition switch follows a close second. You can make a bifurcated jumper cable to temporarily replace the relay. See www.clarks-garage.com

More important is the timing and balance shaft belts. If you have no idea when they were last changed you need to do so now. 30,000 miles or three years is about the limit on these belts. Pushing it is just asking for a head full of bent valves.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?

Go through the no start check list on Clark's garage (www.clarks-garage.com). Make sure you are getting a spark from your ignition coil. Check your reference sensor (there is a procedure on Clark's garage). When mine went out, it gave me trouble starting for a couple days before it totally failed. Checking your fuel pump operation is much easier if you have someone helping you out so you can go behind the right rear tire and listen. Also check the DME and fuel pump relays as others have suggested.

Timing belt is DUE (30K, 4 yrs)! I plan to do it Saturday. I initially thought it beat me to the punch and snapped a couple of days before I got to it. It did not thank goodness.

I had a similiar problem last month. I tried everything above. A senior member of the forum told me it might be a short in the car's factory security alarm module.....Yaeh, no kidding. He sent me a link on how to jump and bypass the module. i did it and prestooooo, it started up and has continued to start up every time.
