eightytwoturbo Posted December 18, 2008 Share Posted December 18, 2008 hey all, havent posted in a while... got a question there is 3 plugs that go into my ecu on my ZXT but there is also another coming off the harness near those 3 that is not plugged up... and i cant find where the hell it goes... is this a boost sensor plug or what? the wires are solid green and black. its a 2 prong plug i believe looks kinda like a "L" shape female connectors Quote Link to comment Share on other sites More sharing options...
eightytwoturbo Posted December 18, 2008 Author Share Posted December 18, 2008 anyone?... im trying to get my car to run right, been through all the normal z bs... cleaning every connection and ground, all my lights are on (fuel, brake, engine, door,) what the heck could be causing this? my idle jumps from 200-1000 and then the car dies. i was thinking a bad ground somewhere, but ive checked and cleaned everything... car was running superb till on my way home from work today. not sure where this plug goes, but since its right near the ecu im guessing its well needed???

eightytwoturbo Posted December 18, 2008 Author Share Posted December 18, 2008 3 connectrs into the ecu, then this random plug that doesnt go into ecu,but near it.. its bothering me... green/black wires Quote Link to comment Share on other sites More sharing options...
nismopick Posted December 18, 2008 Share Posted December 18, 2008 It's not used... so stop worrying about that plug. If all the dash lights are on, the alternator is not charging correctly. Check voltage / amps / wiring. Quote Link to comment Share on other sites More sharing options...
eightytwoturbo Posted December 18, 2008 Author Share Posted December 18, 2008 it started running poor when all the lights came on tho, and a alternator wouldnt effect this would it? also all my inside dome lights are not working, and the fuses are good... they worked fine before this started happening..

nismopick Posted December 18, 2008 Share Posted December 18, 2008 Welp... apparently you aren't going to listen to me. Anyone else wanna try? Quote Link to comment Share on other sites More sharing options...
naviathan Posted December 18, 2008 Share Posted December 18, 2008 Your car uses electronic engine management. If the alternator isn't providing enough voltage/amperage for the EFI then I think that would cause it to run rough, don't you? Quote Link to comment Share on other sites More sharing options...
eightytwoturbo Posted December 18, 2008 Author Share Posted December 18, 2008 now i understand, was having a brain fart... going out there today and working on it, gonna check grounds and voltage, will let you guys know thanks for the help Quote Link to comment Share on other sites More sharing options...
eightytwoturbo Posted December 18, 2008 Author Share Posted December 18, 2008 ok none of my belts are turning over, not even the fan belt... so im really not sure wtf is going on.. im not a mechanic or anything. anyone have a link to a writeup or steps on easiest way of removing the altenator?

nismopick Posted December 18, 2008 Share Posted December 18, 2008 What do you mean "none of my belts are turning over"? Does the motor start / run? Does it crank? Can you move the clutch fan? And the Haynes manual has all the maintenance / repair info you could think of (of download the FSM from http://www.xenons130.com). There's no need for an alternator removal write up... it's easy. You can remove it from the top (remove power steering pump) or from the bottom (remove skidplate). Two bottom bolts, and one top one... and wa-la, it's out!

eightytwoturbo Posted December 18, 2008 Author Share Posted December 18, 2008 motor will start and run with lumpy idle and then wants to go dead without some throttle pressed. just got from up under it, seems like the bearing around the shaft of the fan coming out the head or whatever is busted, with oil around it, still not sure what it is so far, but not looking good. and yes, none of my belts are turning over, even my radiator fan my mechanic buddy is coming over soon to help me out, will keep ya posted Quote Link to comment Share on other sites More sharing options...
nismopick Posted December 18, 2008 Share Posted December 18, 2008 seems like the bearing around the shaft of the fan coming out the head or whatever is busted, Water pump? We really REALLY need to get you up to speed on the technical terms (nomenclature) of car parts. FYI... Get yourself a Haynes Manual or FSM freaking asap.

eightytwoturbo Posted December 19, 2008 Author Share Posted December 19, 2008 well ended up being my crankshaft pulley... its broke where the key holds it in place. the bolt and washer came completely off that holds it on the front of the pulley luckily the bolt and washer was laying in my fan shroud! so im going to be buying a new pulley and crankshaft seal tommorow and putting it back together, im assuming this threw my timing off... so im gonna have to check my firing order. it would crank up previously and sounded normal, just a bad idle. so maybe nothing is internally screwed. will update tommorow.

I am not asking questions now man, i was just wondering if that threw my timing off with the crankshaft pulley broke, since the shaft was constantly turning with nothing holding it tight onto the pulley because i drove it a little ways home, but decided to pull over and get it towed. I am listening so i dunno wtf you mean by that. my issue is solved now, the whole reason before was i thought i had a electrical wiring problem but ended up to be the altenator, but its not the altenator it self... its the crankshaft pulley which turns my altenator, waterpump, powerstearing, ac etc. No flaming here, i appreciate all the help.

240z!!! Posted December 19, 2008 Share Posted December 19, 2008 im sorry i thought you meant it like the only reason your car was running bad was b/c your timing was off.....when everyone told you it was your charging system.....i get what your saying now....but in all seriousness i dont think your timing would be effected...

eightytwoturbo Posted December 19, 2008 Author Share Posted December 19, 2008 ok anyone have a resource online on getting a pulley and the seal that goes into the timing cover? do i need a whole new timing cover just because that seal came out? it looks like it was made onto the cover on the inside..... oreily's parts here in town says its $240.00 for just a PULLEY to fit my car.. figured there would be some universal ones?? what the hell lol. i dont mind using a used one in good shape Quote Link to comment Share on other sites More sharing options...
