the stock ECU cannot hand the amps the aftermarket fuel pump draws and will short the ECU. You need to do a Fuel Pump Relay Mod on these cars to not short the ECU.
I'm happy to see a z31 video. My shitass wants to see a vq35de put in it 😅. Can't really go wrong with an ls motor tho. Hope to see more Z content in the future!
A bad maf had me chasing problems for like a month. I swapped it out got it running great, then LS swapped it. I liked the VG but that LS has so much bottom end torque. I don't regret it.
If that fuse blows again, check for continuity to ground on pin 36 of the ECU. (While still plugged in, backprobe it.) The 02 wiring made me think of how these cars use common grounds for a lot of things, and the MAF happens to share that common ground.... And you removed the air filter and it ran fine... Not to mention, these are self cleaning MAF's, which is probably what kills 90% of Z31 batteries that don't drive often.
You have something else going on if your fuel economy is that low. I have 6 of them and I have never gotten below high teens. I average in the upper 20s. Also, a VG is a difficult engine to blow up. Unless you intentionally do something to kill it, it probably won't die.
Been missing the Z content I just bought a 1985 300ZX Turbo and was watching the 300zx vids here before I bought it now I'm glad they're back!!!

I say let it burn😂
So glad she’s back man you inspired me to fix up my 300zx glad your still updating us on it
How's it going? No new videos in a little while. You doing good?

Please don't LS it! Rebuild the VG 👍
A difficult situation fs
Not an LS dude. Go RB26! Although the LS is probably cheaper and you can get parts at the corner store! 😉🤪

I think I'm leaning towards an LS too.

Love the z content
This makes me think very hard on getting a z31
Everyone should experience the difficulties of the z 😅
Drop the tank yes

I'm sure the O2 sensor isn't doing the right things anymore, and I keep the rpms rather high. Also I agree.. it will never die
