any 1 familiar wit there blazer not starting when hot????

 

i've been browsing the forum a bit and it looks like there's a lot of people with the same problem,cause i have the same problem.

 

More information might help you find an answer. What kind of car is it?

 

cherokee 1989,with a 4.3 i change the spark plug,the 2 injector,cap timmer and rotor,coil.and when its geting hot it spray gaz like crasy that i had to change the oil and filter,and i also change the o2 sensor,i'm on the edge of junking it,it getting expensive.

 

What did the motor come out of? It sounds like a TBI engine, but to assume... In order for us to help, you have to provide information.

 

i'm very new with that kind of motor,i bought that 1989 cherokee for scrap but it was not running good at first so i bought and other one it is a 1991 blazer,so i took the part from the 1989 and i put the missing part on the 1991,and all summuer it was running very good and when it was time to put the plow in front it start running bad,when the 1991 was getting hot it spray gaz like crasy and i had to change the oil and filter,and i change the injectors,coil,cap timmer,rotor,and the o2 sensor,it was the same,spray to much gaz in the injector,so i took the part again and switch to the 1989,when everything was change the same thing happen,spray to much gaz when getting hot,now i dont know what to change,its getting expensive.
