#295 of 317 Re: 1987 turbo trouble or not [mpksr] by zsforever Sep 20, 2008 (6:15 am)
Replying to: mpksr (Sep 18, 2008 4:06 pm) I own a 1986 turbo,I don't think you have a problem.At an idle the guage shows a vacuum of -7 as you hit the acellerater the throttle plate opens thus showing less vac between the plate and the intake,what you should find is that when driving this condition will be noticed as turbo spools and transitions from vac to boost.hope this helps.

Replying to: scanty (Oct 26, 2005 2:29 pm) Thats not really true, if the drive shaft is not true (out of balance) it will still cause the vibe because it is still spinning. shaft doesn't have to be under a load. best thing to do is to jack up the rear install jack stand under the chassis remove the rear wheel put lugs back on spindle and tighten. Put the car into drive and accelerate above 40 mph. if vibe still exist then drop drive shaft and get yourself a one piece drive shaft. you can take your old shaft to your local machine shop and they will build you one using your old yokes. approximate shop time is 2 hrs plus the price of the tube. Total time it takes me to remove from vehicle and reinstall is 1 hr.
#300 of 317 Security System Issue by 89checkmate22 Dec 04, 2008 (1:20 pm)
I have recently swapped the engine in my 88 300zx and have been unable to start the car. The security light on the instrument panel flashes continually after the battery is connected, even after the door locks have been cycled (the recommended reset for the system). I know that the security system shuts off the fuel supply to the injectors and that seems to be where the problem is, since I have established that I have spark and all else appears normal. My question is: would having the rear hatch off for paint be the cause of the security system not resetting and therefore shutting down the fuel supply?
#301 of 317 Intermittent start problem by jim300zx Dec 04, 2008 (2:04 pm)
I have a 1991 300ZX turbo. Occassionally when I turn the key the dash lights up but nothing else happens. If I turn the key a few times it eventually turns over with no problem. Sometimes it goes months without this happening and then it starts happening daily. I put in a new starter, which seemed to work but didn't. I even tried a new key as the old one was worn down. Again it seemed to work but didn't. Any thoughts would be appreciated. Thanks

Sorry I can't help you with your problem, but as an owner of a '88 300ZX, non-turbo, I was wondering what prompted you to swap the engine. How many miles did the original engine have? Replies to this message: 89checkmate22 (Dec 12, 2008 11:48 am)
#303 of 317 Re: Security System Issue (89checkmate22) [hpmctorque] by 89checkmate22 Dec 12, 2008 (11:48 am)
Replying to: hpmctorque (Dec 11, 2008 12:58 am) With 245,000 miles the crankshaft broke. A friend had an engine out of an 86 with 55,000 on it (pulled from his attempt to mate 300ZX and 16 point buck), so after swapping out a few external pieces (pulleys etc) we stuffed it in. Now all I need to do is get that pesky thing to run!!!

Well, with 245,000 miles your 300ZX didn't owe you anything, although I've never heard of a crankshaft actually breaking.   Good luck with getting your Z back on the road.
