The car stalled on me, going up a hill, and it's won't start
any suggestions:

so far I've checked:
60 psi on fuel pressure pump, starts when key turned on
lot's of sparks, 12 V on the igniter
165 psi compression on each cylinder
no faults on the ECU or in the dash, power to the ECU (one blink)
no fuel going to the engine between the line and the injector (s)

any ideas..?
O2 sensor?
car has 85 000 km's (15db1 engine)

My Haynes Repair manual lists these causes for: Engine Stalls
1. Idle speed incorrect.
2. Fuel filter clogged and/or water and impurities in fuel system.
3. Distributor components damp or damaged. (Is the distributor cap cracked?)
4. Faulty emissions system components.
5. Faulty or incorrectly gapped spark plugs.
6. Faulty spark plug wires.
7. Vacuum leak in the intake manifold or vacuum hoses.
8. Valve clearances incorrectly set.

It stalled and won't restart, I have the same book
I suspect #4 faulty emissions system components
but not sure we're to start, is an o2 sensor can prevent a "no start
condition", or an intake air temperature sensor

As far as I know, a faulty O2 sensor never causes a no-start.

In most cases, the engine light would come on if you have problems
with the o2 sensor. One thing that is not on the list is the "fuel
throttle bore". It should be mentioned in your repair manual. You should
clean it. You should also replace the intake manifold gasket.
Did you replace the fuel filter? It's possible that the problem
is dirty gas or gas that has water in it. If that is the source
of the problem--the problem will not go away until you burn that
tank of gas. If you are not a mechanic, you should consider
having the car towed to a mechanic. The mechanic could hook up
the engine to a computerized engine tester and figure out the
source of the problem.

i'd check the main relay, despite the lack of codes. go to tegger.com
and look for the diagnostics & repair.
