JagdStealth Posted April 15, 2006 Share Posted April 15, 2006 '73 240Z with an '81 L28ET all stock... So I finally got my stupid car to spark again, parts store gave me a bad part. I've got spark on all 6 cylinders fine and I have it timed to ~18 BTDC with a really rough idle. When trying to get my car working, I changed the CAS, Coil, Plug Wires, all grounds, cap and rotor, plugs, and ECU. Now I've got spark fine on all 6, but cylinders 4 and 5 I don't seem to be getting any fuel. I've tested spark with a test rod in the end of the spark plug wire and all of them fire fine. Upon inspection of all the plugs, #4 and #5 look clean and brand new without any fuel film on them even. The car "idles" at ~600 RPM, but is very rough and won't rev up very well. I'm thinking that those injectors aren't firing at all. What on the car would cause 2 injectors to not fire? The car ran PERFECT before the power transistor shorted out. I just don't see that transistor shorting out AND two injectors going bad on me at the exact same moment... Could the CAS be out of adjustment some how and not allow them to fire? I've tried moving the CAS to all extremes and, while the car will run slightly different, those injectors still do not fire. Quote Link to comment Share on other sites More sharing options...
Mr.INSANE Posted April 16, 2006 Share Posted April 16, 2006 Have your injectors tested they could be bad Quote Link to comment Share on other sites More sharing options...
