I have an 87 300z non turbo when I go to start it it turns over but it wont start. There is clicking behind where the passenger door closes behind the plastic panel and also the solenoids on top of the coil make noises and the fule pump turns on and off all at the same time. I have never seen anything like this before. Anyon know what could be wrong with it? I need to get it running so I can sell it, I need the room in my garage for a new project. Also if anyone is interested in buying it I want $1000. The whole car is complete and was running fine about a month ago I parked it and now it wont start. Its a v6 5 speed with a bunch of new parts in it including a clutch and lot of new brake parts.

hmm maybe the computer's bad??? isn't the computer located in the pasenger door or something like that???

check the fuel pump relay... that's located around the first area you describe... if that checks out OK then check the fuel pump.... do you hear kind of a whirring whining sound when you turn the key to the 'on' position? does it sort of click on and off once, or is it like a constant tickticktickticktick thing?s

It is a constant click,click,click,click and the only way to make it stop is to remove the battey cable and then put it back on. When I first turn the key on I hear nothing under the hood or in the car click. Sometimes it will only start doing it after i crank it over for a few seconds then it will start doin it. :screwy: :banghead:

sounds like a funky relay to me... not sure which one it could be tho... check your master relay and the relay box near the front passenger's side of the engine bay...

Actuallythe car has a boost sensor on the driver side front fender but I cant really see a turbo from up top on the car. I cant fit under far enough to look from the bottom cause my jack let go. But I can see two small exhaust pipes coming from near the engine and then going into one. Also I think I see some coolant lines near the exhaust also but again its so tight in there it might not be. But there is definately a small box on the front driver fender that says boost sensor on it with a harness going to it thats plugged in and also a vaccume line. the car also has the aluminum wheels on it like the ones i see on your car on the right pic from your posts. Is there any way to tell if its turbo without jacking it up and looking. It will be another week or so before I get a new jack. Thanks for your help man I appereciate it greatly. I have experience with turbo dodges but these forign cars are a horse of a different color. IO like the car alot and if it turns out to be a turbo I will keep it and restore it. I got it off my girlfriend for $1000 bucks when it was running. I never heard the turbo spool up before so if it does have one it must be siezed.

you'd know... look at the guages in the dash, are they voltage and oil pressure, or a dual guage of oil pressure and temperature and another one that's 'boost'... but if you're saying it's got the same wheels as my pic on the right, then either the wheels were swapped or your car's an 86 non turbo.... go check the vin of it and post it on here and i'll be able to tell you the exact specs of the car.. post pics of it..

however, if it has the boost sensor then maybe it is a turbo...

oh... better yet... the piping that goes to your throttle body... is it made of plastic, or cast aluminum/

The plastic tubing going to my throttle body is made out of grey plastic.

I will work on the vin and pics when I go back up there again. Its stored almost 50 miles away in my parents garage.

It does have the dual guage of temp and oil press but the other guage is a volt meter there is no boost guage anywhere. The boost sensor hose goes to the intake manifold near the throttle body. My guess is that it was factory as a turbo but the engine blew so someone swaped a na engine into it. Also the wiring harness has electrical tape all over it. My next ? is does the coil input on these cars run with full battery voltage as the input or is it stepped down befor it gets there. I can smell gas when I crank it over but I have no spark. So im thinking of jumping the computer and running leads to the battery from the coil inputs to see if it will start up that way?

yeah, sounds fishy dude.. the VIN is a non turbo vin, so i have no idea what the boost sensor would be doing in there... the turbo models also came with a cast aluminum charge pipe.. but yeah, it does sound like there was some sort of funky stuff going on in the engine bay... i'm not too sure about the coil voltage... it might even say right on the coil the specs of it.. i've never really looked at it in that much detail.

have you ran codes on the ecu? i'd try that out if you haven't yet.. check out http://www.gowhatnot.com/nissan/frames/menu.htm for all of your manual needs...

Thanks for all your help man, this car looks like a project im not going to get into. Its a shame because I really like these cars, but not enough to deal with all sorts of electrical issues. The more I look under the hood the more stuff I find that is hacked and spliced into. As for the boost sensor I have no idea what its doing under the hood except measuring vaccume. Its wierd because the boost sensor is actually pluged into the main harness and its not a fake so possibly someone changed over the harness also? Reguardless this is one car im not going to get involved with. I have a 2.2 turbo dodge running 23# of boost and thats plenty fun enough for me right now. Car is going for sale first chance I get to put a sign on it. Thanks again for your help man : )

yeah, sounds pretty ugly man.. how's the body on it? if it's in good shape you should hold onto it for a while till you get some free time and money and make an absolute monster out of it... the turbocharged engines (vg30et) are fairly easy to come by and pretty cheap to make pretty fast.. you can toss some vg30dett (z32 [90-96 300zx]) pistons and rods in there and the bottom end will be good to around 750 rwhp... which is more than enough for most people :p with a few head upgrades and a new turbocharger you'll have more power than you could ever ask for.. of course there's all the supl. upgrades, but everything is pretty dang cheap on the z31 (84-89 300zx) when it comes to mods (aside from the clutch for the fs5r30a [87-89 turbo] transmissions... they're just as expensive as the ones for the z32... but they're just as stout as the z32 tranny's (i've seen some well in excess of 650 rwhp holding just fine on stock transmissions w/ upgraded clutches)

either way i'd hang onto it if you can afford to man... they're fun cars and are only going to appreciate as time goes on...

The body is in excellent shape with only one small dent on the passenger side front fender and some minor scratches here and theres nothing that doesn't work on the car except the motor wont run : ( I've had the car a few years already and will probably take your adice and hang on it to it until i decide to fix it for myself. Is it possible to put a turbo back onto the engine that someone put back in there? Or are the internals different for turbo and na engines on these cars. I know on turbo dodges the internals are the same except the compression ratio is lowered slightly to accept the boost without detonating..

the only difference between the vg30e and et are the pistons (et is dished for lower compression) and a few sensors (aac on the turbo compared to idle-up solenoid on the n/a) but yes, you can take the exhaust mani's from a turbo engine, bolt them up to the vg30e and turbocharge it... now you have to be somewhat careful when doing this because of the higher compression ratio of the n/a(which you probably know) but overall it's not quite as high as say a honda engine... i think it's around 9.0.. compared to the turbo's 7.8.... wow.. now i know why my n/a has so much more pep than my turbo around 2000 rpm.. lol... anyway..

yes you can do it, yes you have to be careful, yes it will decrease the life of your engine slighty... yes it's fairly cheap and a good little upgrade to do and is easy to build on after it's done...

if i were you i'd try to find an in-tact wiring harness... perhaps bite the bullet and get a new one from nissan.. it will probably save you a lot of wiring headaches (z31's are notorious for hard to diagnose wiring issues)

sounds like the car is in pretty damn good shape, but they have a tendancy to hide rust well (ask longlivethez who seems to be developing a spot of rust from the inside of his door panel out.... figure that one out??) and like to rust underneath the car... so i'd get under there and check it out just to be sure...

what kind of dodge is it you drive? daytona? ever heard of the turbo minivan? :D

I have an 88Lebaron 2.2t the ultimate sleeper I took the turbo badges off the front fenders also so they have no idea whats coming to them. It was a t1 car(non intercooled 7psi from the factory) Ive upgraded it to an intercooled 23#s of boost with a fifth injector installed into the intake manifold for a little extra fuel with all that boost. I just flip the toggle switch on my shifter rite after it shifts into second gear and the 5th injector starts spraying. I consider the car pretty fast, if i don't nurse the gas pedal it will smoke all 3 gears and the rpms wont even drop at all when it shifts. Also these dodge engines are torque monsters because they are oversquare(the stroke is longer than the bore of the cylinder) Even with pirelli rubbers on it I cant harness all the power it makes. Ant the best part of it is that it looks like a grandma car so the civic thinks hees got this one in the bag lol. I used to own a 98 Mustang Cobra a few years ago and thought that was the fastest thing ever until I built this car :smile: now I go even faster without the huge car note. The only thing I miss is the handeling of the Cobra the dodge cant whip corners like the Mustang could :mad: But in a straight line its quite a rush. And to answer your question on the minivan yes dodge made a 3.0v6 turbo mated to a 3speed auto. A few guys on the dodge forums have them and I have seen a few videos of them running mid to high 11s in the 1/4mile. And before he passed away in a motorcycle accident Gus Mahon's turbo van was running in the 9second range. I couldn't imagine a 9 second quarter mile in a van lol. And the van was a daily driver also all he needed to do was change the front wheels to slicks and bang 9 seconds. He was like the pioneer of modifying the turbo dodges. I would like to get my car in the 10 second range sometime but I need to upgrade the turbo first. Rite now it has a Mitsubishee toe4h turbo anly good to about 24-25#s of boost I would like to run somewhere around 28#s reliably. For that I will need to make a hefty purchase from Turbonetics.
