new fuel filter, and electronic control module.the blazer runs when put starting fluid in there then dies out again. i have a feeling its the security system. i am unsure how to reset it -
Answer 1
Cant be flooding, if it has good fresh gas and not starting because it isn't getting any gas!! If starting on spray then stalls,, fuel pressure test is needed. All this is based on your statment that the fuel pump is working. VATS (security) usually keeps pump from running. -
