My 93 camry is a 4cylinder. I was driving it one day and it was fine. I tried to crank it up late one night (it was cold) and it had a weak crank. I got the next morning, jumped the battery and it gave a strong crank but was not getting gas (I had a 1/4 tank). I had some one change the spark plugs and they advise me to change the distributor cap. I changed that along with the spark plug wires. I jumped the battery, tried to crank it again and it had a strong crank but wouldn't start. I did it again and gave it gas and IT STARTED! I went a few days having to repeat this process in the mornings and the rest of the day it would be fine. My tire blew out one day and my car sat in the cold for a couple of hours. I had to jump the battery, crank it and give it gas again. it started and i went home. the next morning i tried to do my PROCESS and there was nothing. I changed the battery cause it was no good. My fuel pump is working and I know for sure I'm getting no spark. What could it be?
