FPCU bypass?

If I do the FPCU bypass on my Z with a oem fuel pump will it run fine or will it break the pump and do I need a aftermarket one?

CAS question.

Hey, I'm working on a 1986 300 ZX turbo and had a question about the CAS sensor.

This car has no injector pulse and I'm pretty sure I've narrowed it down to the ECM being bad and not grounding them. My main reasoning for that is that it's firing the coils but not grounding the injectors and my understanding is that the timing for both of those is the CAS sensor so presumably it should be good.

My question is just confirming that there isn't any other inputs that control ignition or injector timing.

Some history on the car. When it came to the shop it had no power to anything inside, found a blown fusible link (the black one) and don't know why it was blown. There is clear evidence that the customer was either working on it themselves before sending it to us or had it at another shop (fuse panel cover off, battery hold down off, relay cover behind the battery off) so I'm not sure why that link was blown.

I'm also concerned that a shorted injector caused the driver in the ECM to go bad as well as the link. So one way or another I suppose I should probly check them for resistance....

Thanks.

Spoilers for the Z32

Just out of curiosity, has anyone fitted or used factory spoilers from other manufacturers (I.e. ford, Subaru, etc.)? I wonder if there’s any that fit or look good on a Z32🤷🏼‍♂️

I need help! (Electrical)

I bought my 90 Z32 TT a few weeks ago.

The right side control pod (HVAC/wipers) was dead. As was the clock, rear wiper, and power mirrors...

Headlights, hi/low, parking lights, fog lights, cruise control and Hicas all worked perfectly.

I removed the drivers kick panel fuse block, opened it up, cleaned it, and replaced all the relays and fuses front and back.

I popped it back in and this is where things got weird.

Upon reconnecting the battery, the front wipers activated for one sweep only. I hopped in and the HVAC pod works! So does the rear wiper, power mirrors, heated mirrors, and adjustable suspension, AC radio ... All good.

However, I now have no headlights hi or lo and no fog lights.

Parking lights, tail lights, signals all work. Cruise works.

Front wipers do NOT, and neither washer sprayer does either.

Clock has power but I can see in the LCD that it's burnt so whatever.

All fuses have power. Under hood relays have power. Fusible links by battery all tested good....

Where did my headlights go??? Please HELP!

Spark plug appearance

I’m inexperienced, does this spark plug look fine? It came out of a cylinder that I think is having issues

I want my stock fan back

Fourth efan controller I've had fail in 9 years, third on this car after ~35k miles. Relays went twice, temp set pot went once, this time it looks like the sensor. Fortunately didn't overheat the car. I'm building a fucking harness for this bullshit because I'm swapping new controllers in every two years.

Well, fuck

Hit a greasy patch on the road and the rear end suddently wanted to become the front. All rear left suspension arms are bent, some more than others, subframe bushings are dead and there's some other things, but I'll rebuild it

New ECU sensors where to install them?

So I recently bought this plug in link ecu but being a noob I was unaware that I’d need new sensors… I have test pips coming from CZP with wideband o2 sensors welded on (for an extra cost since it’s NA and not TT) the 2nd sensor (IAT) where would that go installed?? Keep in mind the whole car is NA except maybe a intakes and exhaust

Please help 🥺👉🏼👈🏼
