Hey everyone! I'm starting a new thread since my "help me!" thread got too long and isn't getting any attention now. Long story short, I'm not getting pulses to my injectors. I've been working on this problem for 2 weeks and I can't seem to get it. The car ran before I tore it down to replace oil control rings 4 months ago, so it's not likely a component failed. I'm thinking I put something together wrong. If I disconnect the ECU connector and ground each injector's pins, they audibly fire. If I manually fire them a few times the car will start afterwards for a few seconds from the leftover fuel, so I know it's not a fuel pump or clogged injector issue. The car …

I'm looking to read, modify, and then reburn a flash ROM for a non-Z application. It's car related, but just not a Z. I apologize for asking this here, but you guys are the best. Anyone have a programmer compatible with an AMD part number AM29F400BB? It's a 32 Meg part and has 44 pins. It's a surface mount part, but I've got a 44 pin SMT to through hole adapter socket that would fit into a programmer that accepts 44 pin parts. Anyone got any ideas?

I just saw this on instagram. Not sure where the photo was taken but it's an L series head with FI and a plate on the head that said "Mikuni" and one on the throttle body that says "fuel injection prototype." I've never heard of this. Anyone know what's up?

While replacing my throttle linkage boot today, I decided to remove the entire linkage and clean it up a bit. After wire-wheeling the pieces, I noticed a little rubber plug among the parts but don't know where it came from. Where does this go?

Does anyone know if they sell pigtail connectors for all the efi system? My AFM, TTS, Coolant temp, FIDLE all have connectors that are broken in some way. they still work, but can fall off. I looked around, but could not find any new.

Hi I have an 83 280zx turbo and it has sat for about ten years. Before it had been put up it had a problem that couldn't be identified by the mechanics I took it to. It chugs real bad if you stomp it and the turbo never seems to spool up. So trying to get it back on the road I decided to do a complete once over from fuel tank to engine. When I pulled the sending unit out it had a wire loose and the filter had completely rotted off I took a bunch of pictures if they are needed. I am unable to find a new one under 400 dollars so I figured this one might be able to be rebuilt. Thanks for any help Sent from my iPhone using Classic Zcar Club mobile

Hi classic-z-car-community,I have some trouble with my 280z engine - it is starting very hard - needs a lot attempts and then runs very weak - after getting warm the engine run is getting better, but takes gas very bad - nearly stopping when cold - and misfiring often ...With the following link you could experience the behavior:https://youtu.be/79MqGnp45u4... the engine run half a hour before, so was not too cold. without this it would need 8-10 start attempts until coming to live ...What did I try hitherto:1. as the fuel pump that was mounted (also not original) whas very loud - I ordered an aftermarket pump from zcardepot.com (https://zcardepot.com/electric-fuel-...80z-…

My 75 starts well drives well, gets good gas mileage, BUT has always had a slight miss sound at low idle. I say low idle since when warming up the AAR keeps the idle higher. After it warms up it drops into a recurring miss. I tested things like compression (fine) spark timing (fine) fuel pressure (correct) and vacuum (a little low 17hg at sea level). Since it only seems to miss at idle and reading up on mixture level having an effect on vacuum (I presume do to less than an optimal burn, reducing overall efficiency resulting in lower rpr for a given throttle opening) I decided to try the temp sensor pot mod. I used a 500ohm WW pot, added some bullet connecto…

Hi all, Some time ago a fellow member Lenny was in the process of making an aftermarket ECU which would be a bolt-in replacement for the standard ECU. It was a great idea and I was hoping it would be a success. Unfortunately Lenny was sided tracked and the project stalled. I like the retro EFI in the 280Z, but I would like to have something tunable and it’s getting harder to find good functioning parts for the 280Z. Now for so something I never thought I would do: Fit an aftermarket ECU. Now how to go about it. Which system should I use and should it be a complete swap or partial swap????? The choice soon came down to 3 systems. 1: Th…

Is there anything magical about the direction of the flow through the PCV system? I think I could clean up the engine compartment and hose scheme if I were to reverse the flow direction of the system. So do we have any engine vent experts in our midst? Currently, under low flow conditions (low blow by and high manifold vacuum), it pulls from the tube in the block, through the PCV and refreshes clean air into the nipple on the top of the valve cover. This direction already reverses under high flow conditions, so is there any issue with reversing this direction for the low flow (default) condition?
