94 s10 4 cyl 2.2 why gas in oil

[Rafael505]

Well, I'll start with the fuel injectors, 2 were leaking I replaced them, now when I cranked the truck, gas was flowing out the exhaust, ok well fine ,, haha,, Now? it cranks for 2 seconds and the motor locks, It sounded like its coming from the starter and fly wheel, so I checked them, starter is good , fly wheel looked good but not sure I'd have to pull the tranny out to really get a good look,, I thought I would check the oil well theres gas in the oil,, I drained it and put new oil but still cranks about 2 seconds then it locks ones again,, I can manually turn the motor but not with the key,,,? anyone have an ideal why this is??? Thanks for the help.
