Starter is good fuel pump is good it gets a spark of the from the plugs
To review - - if you have spark, fuel, and compression, you should have combustion.
In this case, if the timing belt is damaged, you might not have compression or spark at the right time.
A faulty crank or cam sensor could cause you not to have spark at the right time.
The spark plugs could be worn out or fuel fouled and not able to fire under compression.
Did the car die or just not start ?
Very possible you had a crank or cam sensor fail while driving.
I would check the computer for trouble codes next.

SOURCE: Cranks but wont start
Did you check the coil?
It's a $45 to $46 item any more and your getting ripped off.
It's behind the dis-cap .
You need to remove the whole distributer and unscrew it from the bottom 4 phillip head screws hold it in not a big deal! Just remember to put the distributer back the same way it went in and DON'T CRANK THE ENGINE WITH THE DISTRIBER OUT!!! I like to take a picture of the distuber with the cap off before I remove it so I will remiber how it was before I took it out and I can put it back in the same way.Also mark the flang of the distuber and the engine block with a marker so you won't mess up the timing.Take your time not a big deal and don't pay ths silly internet site the $ for the solition!!!!!
SOURCE: won't start
check the spark, if spark is weak it will not start, also if battery is weak it will not start, it will crank but most of the AMP from batttery is taken by the starter.

Simple thing to do is have your coils checked.. You should have spark if they are good.. If you still dont then disconnect battery at least 20 - 25 mins see if it resets ecm and alarm. May begin to work properly again..

Crank engine with distributor cap removed, is it turning?
(That is if it has a distributor cap, some newer cars don’t have one)is it turning?
Broken timing belt or chain?
Are you getting power to the + positive side of the coil (small wires) with key on ? Hint; I use a needle pushed into the back of the plug so as not to damage the wiring.
If you have power then wiring from the ignition switch is OK. It usually is.
Hook your test light to the - negative side of the coil (one end on the - terminal and the other end on a ground). You should have power on the - side of the coil with the key on and engine off.
Crank the engine while watching the test light. Get a flashing signal at the test light when cranking?
If so and you have no spark the coil is likely dead.(don’t rely merely on resistance tests for a coil, a weak coil can test ok for resistance but still give no spark.It happens but is unusual. I learned this the hard way!)
No flashing signal?
Check continuity in all primary circuit wiring for opens.
If they are good,
It is time to check the pulse generator in the distributor. (That is if it has a distributor cap, some newer cars don’t have one, if it doesn’t then the ECM or computer sends signal via the crankshaft position sensor and the camshaft position sensor)
With the engine in non-running condition connect your A/C voltmeter to the pair of wires at the pulse generator and crank the engine. You are looking for an A/C signal that makes 4-6 volts of A/C. Got this? If so the ignition module is dead or has a bad ground. If not (more likely) you have a dead pulse generator in the distributor.
If you have three wires in the distributor signal wire you have a Hall effect sensor. I forget how to test that one. (Chrysler stuff)
If this part of the primary ignition tests ok then check wiring to ECM pinouts for opens.Wiring tests ok.ECM as last resort.
Hope this helps...........
Testimonial: "Fantastic! Thanks for the insight and suggestions!"
SOURCE: car wont start, not getting spark
crankshaft sensor, or computer on toyotas then it was usually the distributor or the computer, but the crankshaft sensor might be bad too thats what helps to get you spark.
A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the car. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

the car died while turning a corner and had to be towed. The car was tuned up and timing belt and idle control replaced a year ago.
the spark plugs weren't fouled, and were in pretty good shape. the belts move when cranked. so I think the timing belt is still intact.
