I removed the fuel rail return line and got fresh gas in the rail, but in the back of my mind I thought about the injectors being clogged. Honestly I should have stopped after not getting it to fire off after new fuel and new pump and just removed the rail and injectors to clean and inspect. Just did the EFI relay check and its good. I installed new coil just for troubleshooting and no change. Ill try the oil and start fluid and if no change, ill put the meter down and pick up the wrenches and remove the rail and injectors to see condition. Thanks

Great thanks. When I check voltage its constant when engine spinning with starter . I read where its supposed to cycle to show voltage only when firing the injectors, hence light check on both pins at plug. Fusible links all good.

Saying power starts at the battery was a little primitive for troubleshooting purposes, I thought it was funny.

Until I had seen the FSM here, all I had was a Haynes book to guide me, not much there for troubleshooting my injector problem. Thanks.

So you are saying that the power comes from "the Battery"? Now I feel like maybe your kind of messing with me at this point, no? Thanks for the help.

There's no power at the injector plugs, good ole Fluke and a home made tester with a light bulb confirms. If the ECU is not the beginning power for the 6 injector plugs, where would the beginning be?

82 NA 280ZX. I have fuel, spark, but no power to fuel injectors. Crank angle sensor seems intact(wiring). Car has been sitting many years, has fresh fuel, no blockage in fuel rails. Other than Control Unit, what else will power fuel injectors? It seems hasty to pull the trigger on a new ECM, but as far as I can tell that seems to be the issue. I pulled the ECM out, seems clean, no obvious issues. Any thoughts?

Fairladys were different from 240Z's. Subtle but different. Emblem on the pillar would solve most questions.

My preference is leave all emblems. 240 is a classic, and should be left as such. Besides, most people sitting at the traffic light around you dont even know what "Datsun" is anymore.

I had an 81 do the same thing a few years back. For kicks I went to junk yard (when there were alot of ZX's there) and replaced the airflow meter, everything ran smooth as silk after replacing.

Yes!! I remember that on mi 81 ZX, which was not a GL model. The GL's have a different system. I would have never remembered that if you didnt say something.

I have determined through ringing out every wire in the antenna system, that it only can work with the factory stereo. I have installed an aftermarket antenna, wired it in and works great, just wish I could get my 2 days of ringing wires out back. If theres a way to wire the factory antenna in with an after market system, I would still be interested in the answer, just for kicks.

Please explain. Manual up down? The only switch I have is the factory mid/long range button that was a seperate switch on the radio face plate. The the aftermarket radio, I only have the antenna plug that plugs into the (car) side. Thanks

Installing aftermarket CD player, cannot find power for the electric antenna. I have the prints handy, but where do I hook power (antenna lead) from the CD player to the Car harness? I have an 83 GL with electric tuner. THanks

This is a funny subject. I have a 73 240, and my turn signals were on top, brakes on the bottom. I rewired them to do the opposite. I have seen other 240's where they were originaly set up with turn signals on bottom, wierd.

You need a wiring diagram. All the wires, if original are color coded, ex. a "black" wire with a "green" stripe, etc. I have done well in the past just with the old Haynes diagrams.

There are some Zcar or 510 mirrors on ebay.

I have owned atleast 6-7 240's and 280ZX's, it wasnt until about 2 years ago that I saw prices that were insulting. I always have been able to find desirable cars, that may have needed a little TLC for the right money, and its no secret that you can still do that today. Just a few days ago on ebay, there was an all original silver 240 that still was not at reserve at 14K, and the sad part was that there were like 20 bids for the car, this is ridiculous. I thought this very thing was going to start back in the 90's when Nissan opened the "Z stores", but it didnt take, and things died down. I blame the internet purely for this inflation on a car that is not rare. Other than a few select items, you can find anything you want for these cars, and you can find any car you want in any given condition, so why the big bucks. Whats the first thing you weigh in real-estate, what will it be worth in a given amount of time, the same for "high dollar" cars. 38K is out of line, but congrats to the seller.

There are a few pairs on ebay right now. I have gotten a set from the guy in Bankok, nice.

Not necessarily true. The internet is making many thing "old" go up in price because I believe it is making people more lazy when it comes to the hunt for such items. I bet if you went to CL, Ebay, or just google "240Z for sale" you will find plenty of cars that will come up, in various conditions, but I guarantee you will find one that is close to what you consider acceptable to your specific requirements, probably in a price range that would also be acceptable. Until you get to a point to where you cant find one then we can talk about asking crazy money for the average car, which the one we are discussing is not, but will artificially inflate the average cost. The VW market is the same way, and I have watched as people are getting ridiculous money for a car that is NOT rare. Whether anybody here who thinks about the prospect of making a boat load of money turning an older Z over, just remember, these cars (240Z's in general) are not rare, but a fool and their money will be soon departed.

very cool, thanks.

What finish are you using from the Caswell system?

Where are you getting all the metal work done? It looks like your getting everything in an alcad type coating. looks very nice.

"This as a Brick" Jethro Tull. All of our 240's were new when they released that album. "Forever Changes" Love "Songs of Experience" David Axlerod The Doors Flaming Lips

Nothing specific, just went over to the shelf for electrics and it was hanging on the shelf. By the way, yours did exactly what mine did, one of the terminals on the breaker has broke clean off. I put a 20A breaker on mine, $2.99. Also, when I reinstalled my new breaker, I zip tied it on the outside of the inner structure, there was no way in he11 to get it to go back in the hole.
