Lockjaw Posted June 20, 2003 Share Posted June 20, 2003 Has anyone ever had this problem with their L28ET. It runs for a while and then loads up and cuts off? It isn't fuel related, and when it happens, I get no spark from the coil, although it has power. after a cool down period it fires right up, but when it cuts off and you try to restart it, it acts like it is mistimed. I replaced the coil, and thought that had fixed it, but no go. It usually only happens when the car is idling for extended periods of time. Ignitor, Dizz, ECU? Any ideas? How hot should the coil get, mine gets pretty warm. Quote Link to comment Share on other sites More sharing options...
fl327 Posted June 20, 2003 Share Posted June 20, 2003 spontaneous stalling is a sign that the ignition transistor is shot. fuel filter ok? Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 20, 2003 Author Share Posted June 20, 2003 So where is my transistor? Is that the little ignitor thing or what? Damn I hate ignition troubles. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 20, 2003 Share Posted June 20, 2003 Yeah, the ignitor thing, sounds right. That's the nice thing about the Z31 ignition though, just pick up another at the pick-n-pull for $10. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 20, 2003 Author Share Posted June 20, 2003 I am going to try that and see what happens. This is really frustrating, but we have a brand new pic and pull that opened up. Should be a good time. Quote Link to comment Share on other sites More sharing options...
Guest sukow2001 Posted June 26, 2003 Share Posted June 26, 2003 it might be your ignition module, (it mounts on the side of the distributor) Quote Link to comment Share on other sites More sharing options...
yo2001 Posted June 26, 2003 Share Posted June 26, 2003 that's ok, my car won't crank back due to a luck of spark. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 26, 2003 Share Posted June 26, 2003 it might be your ignition module, (it mounts on the side of the distributor) Turbo and Z31 ECUs do not have an ignition module. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted July 2, 2003 Author Share Posted July 2, 2003 Its not the module unless I managed to buy an bad one. Any other thoughts? Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted July 2, 2003 Share Posted July 2, 2003 At this point, I'd have to say it could be the ECU, although it seems unlikely to me as the ignition signal has no significant power output. Have you inspected the CAS inside the dizzy, or checked for the signal when the car is exhibiting the symptom? That or the ECU must surely be the problem, I doubt you get two bad ignition transistors in a row. Have you tried a different coil yet? I have a spare or two if you need to check it out...

Lockjaw Posted July 2, 2003 Author Share Posted July 2, 2003 Yeah I put another coil in there. I have info that it could be the pick up deal in the Dizz, and I heard the 300Zx one interchanges with the 280ZXT one, so if that is the case I should have one to swap in there when I get home. Man I hate these little issue's. Quote Link to comment Share on other sites More sharing options...

SleeperZ Posted July 2, 2003 Share Posted July 2, 2003 Hey your time dropped, Congrats. Thank you, yes it did. The car is running well. On the 12th I'll get to find out just how well, as I'm going to do some tuning on the dyno with a wideband. Hopefully get the boost up safely, and get 12s easy, otherwise I'll just try to get a 12 as-is; a gauntlet has been laid down in front of me.

Lockjaw Posted July 2, 2003 Author Share Posted July 2, 2003 I got a spare 300zxt dizzy Me too, and the part is the same, at least according to the part numbers online for advance auto parts. So I guess we will see. Sleeper, just throw some more boost at it. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted July 3, 2003 Author Share Posted July 3, 2003 Well it was the CAS, and the 300ZXT one is not exactly the same. The 280ZXT one screws in from the underside, the 300ZXT screws in from the top. Such a dilemma. So I went to the hardware store, got 3 slightly longer screws, and 3 matching poly lock bolts, and here we are. 1 hour later, good to go. Now if I can just figure out how to remove red locktite, I can raise the idle. Its always something. Quote Link to comment Share on other sites More sharing options...
