1991 Toyota Celica, engine turns over but will not start.?

Question

Tested coil and plugs, getting good spark. Checked fuel pump and injectors, checked out ok.After cranking over for a bit, plugs were all wet, dried off and reinstalled. Smelled gas in oil, so changed oil. Timing is at 0 at TDC. Timing belt is ok. Checked all fuses, there ok. The only thing I haven't done is take a compression test. I'm lost on what to do next. The engine is a 1.6l 4ASE. Appreciate any help, Thanks.

Answer 1

How do you know the timing belt is good. It sounds like it jumped timing. The compression test will tell youif the timing is off. (You will have little or no compression)

Answer 2

did you check your timing belt it may have jump.
if the timing belt is ok. disable the fuel pump by pulling the fuse and then start. if it starts up and runs ruff and then smooths out before it dies its the fuel pressure regulator Disconnect the negative battery cable.

Unplug the wiring connector from the cold start injector.

Place a suitable container under the front end of the delivery pipe and slowly remove the union bolt for the cold start injector. Drain all of the fuel in the delivery
Install a fuel pressure gauge in the union bolt's place, connect the battery cable and start the engine.

Disconnect the vacuum sensing hose from the pressure regulator and block it off.

Measure the fuel pressure at idle. It should be 33-38 psi. If the pressure is high, replace the regulator.

if that is not it try your cold start injector
During cold engine starting, the cold start injector is used to supply additional fuel to the intake manifold in order to aid in initial start-up. The opening and closing of the injector is determined by the start injector time switch, located in the thermostat housing. When the engine coolant temperature falls below a certain point, the switch is tripped which opens the cold start injector. As the engine coolant warms up, the switch will eventually close the injector.
to test Unplug the wiring connector and remove the cold start injector from the air intake chamber.

Do not disconnect the fuel line

Remove the rubber cap from the fuel pump check terminal and short both terminals with a jumper wire.

Using Special Tool 09843-30011, connect one end to the injector and the other to the battery.

Hold the injector over a suitable container and then turn the ignition switch to the ON position. Do not start the engine.

Check that the fuel splash pattern is even and V-shaped.

Disconnect the test probes from the battery and check that the fuel does not leak from the injector tip any more than one drop per minute.
Remove the Special Tool and install the cold start injector.

Check the resistance of the injector. It should be 3-5 ohms.

If the cold start injector did not operate properly in any of these tests, it will require replacement.

Answer 4

If your sure you have good spark, the other things that come to mind are a plugged catalytic converter or some sort of ignition timing problem. Also make sure that you have at least 9 volts across the battery when your cranking the engine to power the electronics and computer.

Answer 5

Your right, it could be either, but more likely the cv shaft. This is one thing I would not fix immediately if I was sure the wheel or brakes are not the problem. Watchful waiting, to borrow an uncomfortable medical term. Sooner or later it will become obvious or go away. Have you looked at the cv boot carefully to insure its not ripped? Once they let in dirt, the joint starts wearing. I think this car has rack and pinion, which can fail, but not catastrophically. Check the belts and fluids.
