Leash Posted September 3, 2009 Share Posted September 3, 2009 I picked up a 280z about three months ago, ran perfectly fine and had a 5 speed installed. But just a few weeks ago its just stopped sparking. Before that it made that traditional solenoid clicking sound problem and didn't want to start until you tried again a few minutes later. I've unplugged and plugged back in all the spark plugs (wires are new). It cranks and is getting fuel, I can smell it from the exhaust, but just no spark. Battery is good too. So I've sort of come to the conclusion that its either the: distributor ignition switch starter relay bad wire? aftermarket alarm (that came in the car, looks like a hack job) This is my first z, and the last project car I had was a 240sx, so bare with me if I still haven't got a clue on where to locate certain spots on this car. I work two jobs and go to school so I only have time to work on one of these a week, so I want to figure out what I should do first? I know I'm probably going to have to over all of these, but I'm hoping to save time on some opinions or any other ideas on why its not sparking? Where should I start first?

woldson Posted September 5, 2009 Share Posted September 5, 2009 Have you checked spark by pulling a plug? Check all connectors involved. Quote Link to comment Share on other sites More sharing options...
zuum Posted September 15, 2009 Share Posted September 15, 2009 Don't assume that because you smell gas from the exhaust that you are getting enough fuel in the engine. Its not starting, so even a little fuel gives a lot of smell, I agree with woldson, check for spark by pulling a plug... matter of fact pull all the plugs, they may at the very LEAST need a good cleaning. Check cap and rotor condition. Check for spark at the coil... OH, and go download the FSM, its got troubleshooting section that will do you wonders. I understand you have little time... but if you want the car bad enough, you'll find the time. Quote Link to comment Share on other sites More sharing options...
Leash Posted September 21, 2009 Author Share Posted September 21, 2009 I already tested it before to see if there was any spark. I fixed the problem and i have it running now. The problem was the alarm system. I spent this past weekend pulling out the harness, checked for fried/disconnected wiring, and removed the alarm system. Plugged everything back in and she fired up on the first start. Quote Link to comment Share on other sites More sharing options...
