1983 280zx Won't Crank or start

So i bought this car about a month ago and it ran fine, there was a bit of a tick from the engine and i assumed it needed a valve adjustment but it turns out the engine was recently rebuilt however they didnt put new injectors or anything, I believe this car sat for a long time engine is clean tranny and differential have layer of grime on them. So anyways put lucas in it to kinda clean things out ran better smoother still had the tick, gradually i started getting hesitation when flooring it, super rich smell from exhaust and the cold start injector was leaking a bit, Now this morning on my way to work it dies at a stop sign and wont start back up, im going to replace all electrical connectors to fuel injectors and maybe the whole cold start valve(unless you can get just the injector) but I believe its something else , any ideas as to what may be wrong, i turn key it just tried to start doesnt crank or anything. Need to push it back home from down the street then will check plugs.

also would alternator cause this? all my electrical works but there may be a little power steering fluid in it from leak

Re: 1983 280zx Won't Crank or start

So what i'm getting is that you turn the key and nothing happens. No crank means the engine does not even turn ,like the starter is been taken off the motor. If that is the case then you probably need a new battery. Did you fix the leaking cold start injector, the hesitation problem and the rich exhaust smell when you noticed them or just kept driving it until it quit? How long did these conditions exist before it died?

Re: 1983 280zx Won't Crank or start

Power steering fluid has indeed destroyed one alternator that I know of, from a year or two ago on this forum. Alternators really don't like foreign crud inside them!

You need a good battery with a full charge. It needs to be at least 12.5 volts at rest, and it needs to not drop below about 11.5 volts while cranking the starter. If your battery charge is too low, or the battery won't support the power drain during start, your ZX won't do much for you. If the battery gets too low, the injectors won't inject, the spark system won't fire, the fuel pump won't pump enough, et cetera. Note that those voltage measurements MUST be taken, with a decent volt meter, directly on the battery posts. Do not depend on the dash mounted volt meter. It is not accurate enough.

If the filthy alternator has been taken out by the PS fluid, then you have been running on your battery, and that can only take you so far. If the battery gets weak enough, you can't even push start the car.

Also, use the ohm meter function of your multimeter to check your fusible links, especially the black one. That is the one that brings freshly generated +12 volts to the battery and the car. If it is blown, the battery will eventually be discharged, even if the alternator is actually good.

Download a FREE copy of the original Nissan shop manual for your car, by clicking on the appropriate link in my sig. There are lots of troubleshooting tables and diagrams, things for you to check. If you carefully perform them, you might even fix your problem!

Re: 1983 280zx Won't Crank or start

Well finally pushed it back home going to double check plugs in a min, I guess i had a different definition of crank it will crank battery is fairly new, cold start valve leaking since i got it but very minor. I will double check battery also its just like the engine is not even trying to start just the starter trying to start it, dont know why this happened suddenly? is there anyway to test an alternator and would that make my car die while im driving? Rich smell was there for a month since i bought the car the hesitation just started recently after adding lucas fuel injector cleaner and a little upper cylinder lubricant in the oil (trying to get rid of ticking noise) after first putting those products in engine ran smoother and picked up better but ticking remained

The ticking is either valves, which should be adjusted every 30,000 miles....or the fuel injectors which will always tick. The valves are louder...the tic tic tic tic is probably the FI.

Re: 1983 280zx Won't Crank or start

You can take the alternator into just about any auto parts place and they can test it for you.

In your SUBJECT, you wrote "won't crank or start". Yes, when I read "won't crank", I understand that to mean that you can't get the starter motor to do anything, except possibly to make clicking noises. "No start" to me means just that, which can include starter motor problems. "Cranking" and "turning over" to me are the same thing.

Re: 1983 280zx Won't Crank or start

So plugs were all dry and after busing it work work the past few days im kinda pist because a wire on the ignition coil was crimped instead of tightened with a small nut. starts up fine now still running incredibly rich, when i rev to close to redline i get a large white smoke cloud and some type of liquid shoots out of the pipe. Last tank i filled got me 200 miles so i guess ill go to work diagnosing that issue, thank you all for you input and any input you may have with the running rich issue, also clutch pedal is hard to push lately and doesnt pop back up? Clutch MS resovoir fluid is black will bleeding the system make pedal more responsive there is no slipping at all revs seem to match acceleration. is there a bleeder screw on the master cylinder?
