This car sat up for a couple of years. I replaced the plugs, wires, cap, rotor, cleaned injectors. I am getting good spark at the plugs. We had it running well several weeks ago. Since then I had to replace the clutch slave/brakes so I could finally drive it. Not it runs like crap. When I hit the starter it fires right up and runs OK for a minute then gets worse then dies. Then it will not start The following systems have been ohmed out and are within spec. Idle Throttle Switch-OK Full Throttle Switch-OK Air Flow Meter Resistance-OK Air Temperature Resistance Sensor-OK Water Temperature Sensor Resistance-OK Air Regulator and Fuel Pump Circuit-OK ECU grounds (4)-OK I al…

I picked up a pair of these half shafts to go with an r200 diff with an OBX. I have found a place that still carries the CV boots but wondering if this is a rebuild that can be done by a backyard mechanic? How the heck do you get into the inner boot? Thanks, Chris

Auxiliary Air Regulator --- Testing and Adjustment by Wade Nelson My 280ZX doesn't start as consistently and quickly as a fuel injected vehicle should, which is immediately on the first crank. Sometimes it takes several cranks, sometimes it'll barely catch and I have to pump the throttle to get it up to a normal idle speed, all of which indicate something isn't right. But from then on it runs great, so I've never worried too much about it. Bigger fish to fry... I also noticed I don't seem to get much if any idle-up on cold starts, higher RPMs which should gradually decrease. Themotyme / Cold start injector APPEAR to be working, at least intermittently, so this pointed…

Hello, I am fighting the California smog police and need some help with the emission equipment attached to the intake manifold. I am look for the differences between a 1977 280Z California manifold and a 1982 280ZX California manifold. Specifically I am looking for the differences in how the BCDD and throttle body attach and are connect to the vacuum lines. I think the 1977 has the BCDD on the throttle body and the 1982 has it on the intake? If anyone has pictures of how these two manifolds, installed, with the emission equipment attached that would help a lot. I have checked both FSM's but the pictures aren't very clear and the description leaves much to be desired. Than…

I finally bought the Z car I always wanted (well I can't afford a 240) a 1979 280ZX (which was the year I went in the Navy and while other guys had Z cars I had a 1974 Ford Country Sedan Wagon . Just drove it home and after running fine for about 20 minutes when I got on the freeway it started to "jerk" by losing power going up a slight incline and then surge back gradually going from 65 to 40 mph. I tried to nurse it home but it got worse until it was doing it on the level road and I finally pulled over and got a tow. Called the guy I bought it from and he suggested the fuel filter which looks new (he took the car on trade) but I'm going to go get one and replace it. …

I plan to use this in my 75 280z. The oil gutter was broken, oil leaked out from the shifter. I am in the process of replacing the missing gutter, put on some new seals while I have it apart and examine the bearings and gears. Could use some help on the oil seal on the shift rod.

Can anyone CONFIRM the location of the fuel pump CONTROL relay on a 1980 ZX? Not the fuel pump RELAY, which is under the dash, passenger side, kick panel But the fuel pump CONTROL relay. (designated: Fuel Pump Relay-2) in the schematic. The EFI bible APPEARS to show it in the in-engine bay relay block. The diagrams are wrong for my 1980, for starters I don't have an automatic transmission but I have a relay in the socket labeled "Inhibitor Relay, A/T", I have three sockets in the rear row, not two, although only two are populated, etc. Here's what's interesting. With that relay PULLED, when I turn the ignition to the on position the fuel pump runs. With that rela…

While driving the 79 I notice a fairly loud whine coming from the rear. I'm assuming it's the diff. I have an 83 Turbo parts car. Will the diff fit? Should I change the shafts as well?
