I searched and couldn't find the answer.My 83 280zx turbo isn't getting any spark.The ecu,ignitor,distributor,coil,afm are in good working condition.I know this because i tested them all on my other 280zxt.

I cleaned all connectors,pulled the ecu plugs in and out 8 times and still no start.I did use one of those spark plug testers.Could a bad ignition switch be the problem?Any advice?

you should go buy a digital multimeter(you can get them at autozone or advanced auto whatever) its only like $13 and it helps ALOT with what your dealing with

one bad wire or connection could be your culprit

Is the coil bracket that grounds the ignitor securely grounded to the body? The ignitor must be grounded or no spark...

mikep

Yes, the coil bracket is tight and secure.I'll re-check all of the connections.

Is the ecu getting power?

mikep

Yes, the ecu is getting power.The fuel pump turns on for the 5 sec period.That's why i was thinking it maybe the ignition switch.

I went through two ignitors in three months. Same ****, no spark, it would die at idle, all sorts of weird stuff. Even replaced the CAS(lifetime warrenty, why not.). Bad ground. Cleaned battery terminals, took all the grounds off cleaned em' and put a little grease on the bare metal to cut the corosion. No problems so far and its been 8 weeks, at least. I think those ignitors are pretty sensitive to resistance. Worked for me, FYI.

Iv'e been out of town for the week and didn't have time to work on the z.Thanks for everyone's input.I'll be working on my car in a few days.I'll re-check all connectors and grounds.
