EZ-E Posted March 18, 2006 Share Posted March 18, 2006 I have intermitently had this problem with my 82 280zx turbo. It has to do with the ignition. When I turn the car on instead of starting a relay, which sits on the passenger side, behind the lower lamp cover and next to the large harness plug that meets from parts of the harness that go to the engine bay. It will click, I will not have any ignition at all whatsoever. The car will crank, fuel will be delivered, but I will not have any spark at all. Usually I would leave it on for a short while and it would then stop, Ic ould start my car, but it now just keeps clicking. I cannot tell you what wires go to it now as it is dark out. I will report more tomorrow. I know from tracing wires to this particular relay, that it is part of the ignition circuit. If I remove the fusible link wire, the one labled IGN, it will stop clicking, if I unplug the relay behind the plastic cover next to the battery, it will stop. I just do not understand though what is causing this, I have pulled all the wires and cannot find any shorts or any parts of the wires that looked frayed or burnt. None of the connections are burnt or discolored. I cannot find any part of this that is that is bad. I cannot find anyone that has ever had this sort of problem. I have replaced to the tune of 120 dollars worth of relays and such and it still goes on. All new fusible links, and it still works. Craziest thing is it just started this again yesterday, after a 4 month leave of absence. Please anyone help. Also if anyone could at least find me a safe way of bypassing this relay so I could start and drive my car safely would also be appreciated.

EZ-E Posted March 19, 2006 Author Share Posted March 19, 2006 Could it be in the ECU or the plugs of teh ECU. I was getting tired of it clicking like it was, the relay, so I figured I had nothing to lose. With the power on though I know your not supposed to do it, but with power on, I removed all the plugs to the ECU. Waited five minutes, and there you have it, problem solved. Today the same thing no troubles. Im wondering if I have a loose wire to the ECU that is causing this? Possibly? Quote Link to comment Share on other sites More sharing options...
Mr.INSANE Posted March 19, 2006 Share Posted March 19, 2006 Maybe you got a burnt fusible link they can have weird behavior sometimes Quote Link to comment Share on other sites More sharing options...
VRJoe Posted March 19, 2006 Share Posted March 19, 2006 Check the standard issues. Check all the grounds. Clean the contacts. Clean the battery terminals. Check the battery cable ends (check for corrosion inside the cable at the connectors). Check every connection in the trouble area. Check the relay and make sure it's sending power to the coil. Unplug the connectors and clean with contact cleaner. - Joe Quote Link to comment Share on other sites More sharing options...
EZ-E Posted March 20, 2006 Author Share Posted March 20, 2006 Maybe you got a burnt fusible link they can have weird behavior sometimes I have changed them all, I have searched before and could not find anything wrong, it is disturbing. Since though I have unplugged and replugged the ECU the problem is gone again. Im wondering if there are any problems maybe with my ecu.

VinhZXT Posted March 24, 2006 Share Posted March 24, 2006 The 280ZXT cars are famous for intermittent problems with the ECU connectors. I replaced my ECU connectors with the newer 300ZX connectors and no more problems. the 84-89 300ZX ECU connectors are the same as the 280ZX turbo's connectors except for a couple of missing wires. I suggest you to go to a junkyard and cut them out of the 88 or 89 models since they are still new and splice them into yours. GL Quote Link to comment Share on other sites More sharing options...
