Heyas,
I bought this 74' 260z and after 3 days of running great the damned thing just stalls while I'm working. So I pull off the road and jiggle some of the connections before the distributor. The beast starts up and I start driving, about 15 minutes later it does the same thing, so I go f*ck I'm gunna have to rewire the damned thing and get out to mess about with the connections again, this time no dice I screw with it for about 30 minutes and then out of the blue it fires up, goes
3 blocks down the road and dies. I ened up towing it home later that night and since have replaced, the cap, rotor, plug wires, coil wire, and the ignition coil. And spent countless hours with a multimeter messing about. And the damned thing will not get spark. These 74's have some bullshit ignition system, apparantly they only did it like this this year, and the part I think may be broekn is the T I U transistor ignition unit, which according to nissan they dont have and is some early version of an ¿ecm? I opened up the black box that is the TIU and the board of archaic ressistors looks fine, no blown parts....Anyhow what I am wondering is if anyone else has had this kind of problem, and if so how did you fix it? Or how do you test the TIU? According to chiltons you have to take it to a dealer, but nissan wants nothing to do with it.
I am not getting spark at the coil, or at least the way I am doing it (holding the distro end of the coil wire a little bit above the chassis and having someone turn it over) any suggestions of where to look next?
