SageLaw92 Posted January 16, 2019 Report Share Posted January 16, 2019 My friend has had this Maxima for a while, not running for a bit more than a year. He recently told me if I can fix it I can have it. Few cosmetic issues, I'd like to get fixed of course, though my main problem at the time is it won't stay running. It'll fire up then die a few seconds later. If you push on the gas at all dies faster. Also I replaced the spark plugs, first thing of course, with iridium plugs, after doing a few things here and there and the test fires my first four plugs are wet fouled. I've replaced all the vacuum lines I can find, I'm just at a stalemate of whether or not to go fuel injector route, headgasket, or fuel pump. Anyone got any advise? I can post pictures if needed or wanted. Quote Link to comment
datzenmike Posted January 16, 2019 Report Share Posted January 16, 2019 I don't care for iridium plugs. They are high tech for high tech engines made today not 35 years ago. I hope to hell they are NGK because these are what Nissan made them with. Off the top of my head, I would say maybe the fuel filter is getting plugged up. If you don't know when it was last changed try a new one. If you plan to own this gem a new filter is no big expense, and if it fixes the problem... an easy fix. See if you can find a way to test the fuel pressure. It should be over 35 PSI. If it isn't the fuel filter maybe the pump is going. . Quote Link to comment

My battery is dead so I have it on the charge at the current moment, I cleaned out the filter today to see if that helps any. It was kinda Grey washed at first then after a few flushes started getting clear. I'm going to try an start it again once I have the battery to power. Quote Link to comment
datzenmike Posted January 16, 2019 Report Share Posted January 16, 2019 I don't think they are meant to be flushed only replaced, however if this fixes the problem you know the cause now. X ed fingers. Quote Link to comment
SageLaw92 Posted January 16, 2019 Author Report Share Posted January 16, 2019 It didn't work, I'm in the process of working out a way to test the fuel pressure before and after the filter. Though I got new information about the car, it was ran completely out of gas before dying completely on him. I filled the tank to reset the pump, though I'm not sure if it's full enough. I got it just below the full line. There could also be a clogg somewhere I'm guessing or that is what finished off the filter. Quote Link to comment
datzenmike Posted January 16, 2019 Report Share Posted January 16, 2019 The reason for not running out is the the pump is cooled by the fuel flowing through it. If it's humming along empty it may be damaged. This is good to know. You may get it for the price of a new electric pump. Quote Link to comment
SageLaw92 Posted January 16, 2019 Author Report Share Posted January 16, 2019 It's definitely not empty anymore, though it does make a weird humming noise. The usual mmmmmmm with another weird sound coming ever so slightly through after filling it up. Quote Link to comment

banzai510(hainz) Posted January 16, 2019 Report Share Posted January 16, 2019 Is this Fuel injected vehicle? Quote Link to comment
datzenmike Posted January 16, 2019 Report Share Posted January 16, 2019 All 810s and 910/Maximas were, it should be. Quote Link to comment

Bleach Posted January 16, 2019 Report Share Posted January 16, 2019 The engine should be an L24e. Almost identical to the 280Z L28 with fuel injection. The 5-speed manual is somewhat rare for those cars. I think you can use a 5-speed from a 280ZX if you ever need to replace the transmission. Quote Link to comment
Crashtd420 Posted January 16, 2019 Report Share Posted January 16, 2019 I would look more at the pump and your fuel pressure..... Sounds exactly how my Chevy acted when my fuel pump died .... it would still idle then die with any touch of the pedal.. Quote Link to comment
datzenmike Posted January 16, 2019 Report Share Posted January 16, 2019 A ZX (non turbo) transmission will literally drop in. The internal ratios are fine for the larger L28 and a bit more work for the L24. The overdrive is about twice as high so perhaps a 280z or 620 5 speed would be better. Quote Link to comment
SageLaw92 Posted January 17, 2019 Author Report Share Posted January 17, 2019 It ended up being my fuel filter, and the tps in inoperative. The fuel filter was so clogged it weighed about 10x more than the new one. Got that replaced wanted to run more, was still dying at the pedal press, found out the tps was malfunctioning got a new one on order now will find out more tomorrow whe. It gets here. 1 Quote Link to comment

So the thing about this car other than getting swiped by a drunk driver on the passenger rear side busting the tail light housing, and sitting for a bit more than a year it's in prime condition. It only has 102xxx miles. After everything I've replaced, once it runs, it'll run good. Quote Link to comment

It is quite rare, from what I understand of the 83 models the one I have was model #4. Quote Link to comment
ArchetypeDatsun Posted January 26, 2019 Report Share Posted January 26, 2019 Run regular NGK plugs. iridiums is what I run for my turbo maxima not need to run those on a NA L-Series. Also check your fusible links those love to burn out one of the biggest problems with most 810 & 910s issues and if they aren't bad they will be. You can replace them with maxi fuses they usually come in a nice clear cover fuse box. Also check your Air Flow Meter pop the black plastic cover and see if any circuit has burned out or the little plastic arm hasn't fallen out of place. Quote Link to comment
