1mz-fe engine. What's the repair history on your car?
As you crank your engine, tiny amounts of fuel is sprayed from the injector into the combustion chamber so combustion can occur, the amount of fuel is very little cause its in spray form not enough to even wet your spark plugs.
For you to be able to detect trace amounts in your engine oil means one or more of your injectors is stuck open when cranking, this will cause your engine to freeze while trying to crank until you unscreew one or more of the spark plugs on the affected cylinder(s) to relive it of the excessive fuel.

This problem can be caused by a defective ecm(brainbox)

Don't try forcing the car to start once it freezes or risk damaging your engine.

Can also be caused by a faulty injector with bad seals.

OP, if this were my car.

1) I would use my air compressor to blow the vapors out of the combustion chamber.
2) Drain oil and replace with fresh oil and filter.
3) Attempt to start the engine.

If it starts then I would keep an eye on the condition while I try to find a reputable place to rebuild my injectors or buy new ones.

Thanks cityng for reminding me I edited it a split second b4 you quoted me.

No worries mate, we're all together on this.

There is a check engine light you just can't see it you have.

Have mechanic change all plugs the check the ones that are wet those cylinders are where the problem is it might be the. Coils or wires but that is a bad misfire
