ok pt 2 on my 94 j30.you guys were right but

[jamesj30]

finally the security light is off.i went outside and tried the 6 times in the ignition thing and it worked.thank you so much.but you guys were right it has nothing to do with the check engine light.its still on.and it still runs rough.so i took it to the infiniti dealer and they said it was the # 5 injector.they said it was shot.and since the maf and fuel injectors share the same circuit thats why the maf is throwing a code too.does this seem right?thank you guys for all your help

Could be right but the MAF is known to fail. How much did they quote you to fix the injector? I just posted in another thread about getting the injectors rebuilt and you might want to look into that as it's only about $20 each instead of $100 each to replace.

they said 550 for the 1 fuel injector and 1700 for all 6.parts and labor.theres a infiniti place out here that has them for 220 for all 6.used or 80 new.so is that # 5 injector hard to do or can i do it.also does anybody know for sure if the fuel injector circuit and the mass air flow circuit are the same line or circuit.or on the same relay or whatever?thanks for the help
