I'm assuming that since you drove it home that the engine still cranks over and that it is not a battery issue like one of the other answers. If it does, but still doesn't start or tries but doesn't run smooth, that you may have gotten moisture under the distributor cap. That wouldn't show just by looking at the engine bay. You would have to look under the cap to be sure.

SOURCE: 1994 corvette wont start

Dunno if it is your problem but have had this same 'died without warning' effect from nothing more than a corroded battery clamp or terminal at the starter with the same problem.

A cheap multimeter will tell you if there is any life at all and by measuring at the terminals when having someone turn the key, then doing the same at the clamps themselves will tell you quickly if it is simply failed contact at the battery.
If the battery measures ~ 12.6 volts with no load (nothing turned on) and still the same with the key turned to start, then the terminals are at fault.

Something I have never seen before happened to one of our sons just yesterday; his Optima (costly) battery lost contact INSIDE of the battery!
It measured zilch until we dropped it on the ground (on purpose) then it measured normally 12.6 VDC.
We reinstalled it and again, as soon as he attempted to start the Jeep, even the underhood light went out and didn't come back on and the battery again measured 0 volts.

NORMAL, BELT SLIPPING. CHECK THE P/S FLUID. IF IT'S BRIGHT PINK OR MILKY YELLOW THERES WATER IN THE FLUID AND NEEDS TO BE DRAINED AND REFILLED.

The troubleshooting charts for your ignition system are copyrighted and I cannot post them here. You can have access to them by subscribing to alldatadiy.com fo a small fee.

The MOST LIKELY cause of your problem is a failed distributor module. (inside the distributor) The symptoms you described can also be caused by many other things like loose or corroded connectors or even a failed Powertrain Control Module (PCM)

SOURCE: Code P0342 - Chevy Aveo Sedan 2006. Last 2 months, when starts the car engine getting

Hello! The trouble code is telling us that the voltage to the Camshaft Positioning Sensor (CMP) is low...The connector that plugs into the sensor could be open, the sensor itself defective or low battery input to the sensor...See diagrams below as to sensor location...Lets eliminate...The wire colors in the CMP plug are...Pink...Black/White...And Light Blue/Black...If you connect a voltmeter to the Pink wire you must read 5 volts...Push a safety pin into the rear of the in-place connector into the Pink wire so it contacts the pin that the wire is crimped to...(+) probe of meter clipped to that pin and (-) probe to bare metal chassis ground...Key on...Meter set to read 5 volts...If 5 volts is present that eliminates a battery fault...Next push the safety pin into the Light Blue/Black wire...Turn on key...(+) probe to that pin...Should read about 2.4 volts...If you read nothing, or less than 1 volt the sensor is defective OR the connector pins to it are fouled...Pull plug and inspect both male/female pins for oil...corrosion...etc...Radio Shack sells a product called DeOxit...It's the best (no touch) spray contact cleaner...Send results...PS...Best meter to use is a digital one...$20...Guru...saailer

1994 Cadillac deville starting problems

As with any no start issue, someone will need to check for spark at the plugs and fuel pressure at the injectors to proceed.
Could be a relay or the fuel pump, or a long list of things.

1994 Toyota Tacoma PreRunner - won't start with new battery, lights won't come on

Check your battery connections on the battery and the other ends where they go the ground will go to the engine block and the positive to a solenoid make sure all of this is tight and has no corrosion. This is just a loose wiring problem

Check the fuel injectors, with the key on one side of the two wire connector will have battery voltage, if none is present then check the ECM fuses in the underhood fuel box.

Your engine may look nice but the electronics on it absolutely don't like water. Unplug every connector and dry them out, one at a time and hope for the best. The entire system reads subtle changes in current...water will change those readings enough for the computer to get totally confused. Also, check inside the distributor cap...often water will steam off the engine and condense inside cap causing ignition system to cross-fire.
