My 93 Toyota Camry stopped running when I was driving last week. It appeared we had run out of gas but we put gas in it and would still not start. We have also replaced the spark plugs, a piece inside the distributor I believe and the ignition coil and the car still will not start. It seems like it is getting gas because the plugs smell like gas but I am not sure what else it could be? Any ideas as to what it could be would be a huge help.

. Test all under hood and under dash fuses with a test light or multimeter:

. Check for codes.

. Check for spark. Perform the standard spark test; i.e. remove a spark plug wire and attach it to a properly gapped spark plug, touch the plug to a convenient ground, and observe the spark, while someone cranks the engine. Look for a good, solid spark. If none, I would replace the Ignition Control Module (ICM). I recommend replacing ICMs and coils every 120,000 miles or 10 years, whichever comes first.

. Check for fuel. Can you hear the fuel pump in the gas tank run, when the ignition switch is turned to ON? Replace fuel filter, if it hasn't been done in the last 30,000 miles.

. Check for power to the distributor. If none, check the ignition switch.

My gut is that the ICM is bad.

Does the engine seem to spin faster than before? You may simply need a new timing belt.
Remove the distributor cap and crank the engine briefly while you or someone else watchs for the rotor to turn. If it doesn't turn while cranking, have a new belt installed. Now might be the time for other stuff, too, like front engine seals, etc.

Good point, CaptainRich, that the timing belt may have snapped.
