Was getting bad exhaust fumes in the cab - especially with the windows down in my 77 coupe. Found that the lady who owned the car before me had her friend do some wiring, and the wiring harness dealing with the thermotime switch and related items was jerry-rigged. 3 or 4 wires twisted together, a few were not connected to anything, etc.... (remember that I am the non-mechanic guy on this board). NISSAN went through it and installed the correct harness. This reduced CO count from 4.63 to 0.16 and the NOX went from 161 to 102. Drove tonight with windows up, and down, and didn't smell a thing. My MPG is still at 16 MPG so I will have them run the tests for that on Page 42 i…

Hi Guys, I’m back with more problems. On the last episode I had finished replacing my head gasket and after a few issues (rough idle, gray smoke, etc) she started running fine. Now a few days later I’m having issues again, she’s running rough, can’t really idle on her own, gray smoke out of the tail pipe. So far I’ve checked the wires, plugs, vacuum lines and try adjusting the timing, since I don’t have a timing light I’ve simply tried moving the distributor just a little to see if it improves (I’m picking up a timing light tonight). I’ve done a lot of searches and tried what was suggested without luck. I’m not sure what else to do at this point, any s…

I have a fuel pump proplem and I have went through every thing but still can't get it working. I have no power to it and no fuel gets to my injectors even when I hot wire the pump. I have replaced the computor and fuel pump relay and went through all the steps that my manuals say to go through. I just found out that there is a accessory relay some where on the car that in its info says it controls the fuel pump. I bought it and now I can't find where the dang thing goes. I need to fix this asap if anyone knows where it is PLEASE let me know. Thhanx alot. This is a 77 datsun 280z

So I think we finally narrowed down the issues with only being able to go half throttle to the vacuum advance. I've been looking for the part everywhere, but can't seem to get any hits. I'm not sure if I'm asking for the right thing. We've been going for a Vacuum Advance Canister, and they've been looking into the distributor parts and still can't find anything. I'm wondering if anyone knows the exact part name for this, or if you may know where to get one. It's the little saucer that's attached to the distributor. When pulling off the vacuum line and sucking on the line, nothing changes with the way the motor is running. It also seems to be stuck when we pull the c…

Well I've pretty much ruled out getting the Airtex/Master pump since I've heard bad things about them. The Bosch one is 275, a little too much for me. The Delphi one is about 160, so it is a middle ground. I checked my old pump in the car and it does not appear to be a stock one, so a rebuilt one/send back core isn't possible either. Anyone used Delphi? I know they are GM's supplier for many parts (although I believe they went out of business a few years ago). The O'Reilly site lists Delphi as "actual OE part" which sounds good. I am hesitant to get the Bosch in case I have other problems (fuel tank, etc...) that would make it go out. I plan to put a new regulator i…

I purchased the water temp sensor and holder from MSA for my 72 and cannot get it to thread into place. On close inspection the leading edge of the threads on the engine are a bit messed up. I went to harbor freight to get a tap and die set, but they didnt have anything that seemed to match exactly. The closest i could find was a 16 x1.5, but the holder didnt want to thread into that. Does anyone know what the proper size should be for me to repair the threads? Thanks

These air filters were in a box labeled "240z K&N air filters" when I bought the car, It looks like they have been mounted but never oiled and run. I have been looking all over but I cannot figure out who manufactures them. I have seen similar ones but none that have this bolt pattern, If anyone could tell me who makes them I would be very greatful. http://s284.photobucket.com/albums/ll29/twnygren/240z/?action=view¤t=CIMG0601.jpg

Hello Classic Z members, I just got a new fuel pump for my 02/1977 280Z and need some help on this. I swaped over to SU carbs from the EFI system recently and I bought an inline low pressure electric fuel pump. I am putting in a Push button ignition also and want the new fuel pump on it's own switch, and have the ignition just run the starter and acc power with an ignition switch and hidden starter button. How would I go about wiring this right way or is there an easy way to do this? I'm going to run the fuel lines over again also, so whats the best size fuel hose to use for this and how do I run them to my new SU's? I have an old service manual (with no wiring diagram…

I live in Houston TX and it doesn't get to cold around here very often, but it seems that every time the a cool front comes along my car starts to hesitate on accelleration and run a little rough. It feels almost like a have a clogged fuel filter. As soon as it warms up again it runs perfectly. Any tips on what to check out?

I seem to be having a problem with my Alternator. Battery died and now not charging. Problem is I don't know what type of Alternator I have. My Z is a 75 280z with a 77-78 engine. So i'm not sure what alternator is in it. Also some wires seem to be cut and spliced together right next to it that make me think it might have an internal voltage regulator. I took a pic. Let me know what you think. Is there anyway to find out what type of alternator it is or should I just get a 75 280z alternator??

Need help here rather badly. See engine and drivetrain post for the whole story. But the short part is, how hard is it to get the cam sprocket and timing chain back on the head if nothing moved during a head gasket swap? I cannot seem to get the parts to line up, there is about a 1/8th in. too short. I am guessing that I have made more work for myself because the timing chain tensioner somehow moved during the head removal. if so I have a problem and have to tear down the whole front of the engine. Am i missing something simple? the chain and sprocket line up properly, marks are correct I even maked three seperate locations with paint dots to make sure I realigned …
