I washed under the hood of my 1993 toyota corolla 1.8 automatic and blew it out with a gas blower as dry as possible. It started and was idling for about 5 minutes a little rough so i cleaned the distributor cap and rotor and started it back, it idle smoothed. Then i went to give it gas and automaticly shut off and never started back, i am definately not getting spark, i did the spark plug test, what can be the problem?
