need help im lost now
ok guys ive been trying to catch this little demon miss i got. what ive already done: plugs twice , wires , cap , rotor , tps , iac , air filter , water pump , clutch fan , both temp sensors , belt and tensioner , and replaced all 6 injectors with junkyard injectors out of a 4.0 jeep with new o-rings. now what the truck is doing: i still have a miss i cant track down. ive gone as far as pulling the passenger side fuel rail off sticking the injectors on it and hooking the connections to it and firing the truck up spraying fuel into a catch i made now all 3 injectors are spraying fuel ( the reason i say the passenger side because i pull the connector when everything is hooked up and it seems that there is no change even to a buddy i had help me the middle injector on the passenger side ) ive taken i test light to everything and i am getting power. im simply out of ideas and things to try. and if you have any suggestions of any detailed areas i.e.-injector splice please include i diagram i cant seem to pull them up myself. thanks guys yall have been a huge help . oh btw the truck is a 95 dakota sport club cab 2wd with a 3.9 v6 and automatic

oh and i did the check engine scan with the blinking lights and i came up with 12 , 27 , 17 , and 55. 12 and 55 are no big deal i know that but 27 says injector control circuit failure and 17 says closed loop temp not reached or engine cold too long

your computer controls your injectors if I am correct you might want to try that next. it is plausible that it is in the wiring some where but i dought it since it is a gremlin and isnt there all the time. my wifes car had this problem and we replaced everything but the computer. so stands to reason that you should try that one next. if I am wrong then you should try your splices in your ingnition system. but my money is on the computer.
