Ka24de dies when throttle applied - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Night drifte89 · 09-04-2014, 11:30 AM

I have a 93 dual cam that I just put used injectors in and it starts and runs, but when I give it gas it will die, video shows. Basically are the injectors junk or what's my problem?

Any and all help is appreciated, thanks

Why did you install the new injectors? and have you tried any diagnostics on your own?

First place i would start is unplugging the maf and trying to run it. See if there are any changes. of course it will cut at 2.5k, but see how it revs up to there.

It had a Ka-t in it and he left the sr injectors in the car, so I needed to get stock ones, and I did get a new maf and wired it in, I will try to unplug it in a few mins and report back

^ like he said, ecu could be tune for a turbo, barrow a stock ecu from a friend or something and try it. usually if the ecu is shop tuned it will say so with a sharpie on the ecu it self

I will look, I think it is stock, but I don't have any friends with a 240 #loner I'll have to buy one and rule that

take the cover on and look for anything that seems like it shouldn't be there, use Google for references

Basics man. You need compression, air, fuel, and spark... Easiest are compression and spark. On an N/A you pretty much just assume you get air... So, with that...
Compression test engine. And either lay a wire on the head for spark. Or pull a plug and wire and look at it while cranking. Do this for each cylinder to verify spark.

As far as compression testing: warm up engine to ~120, pull all plugs, pull fuel pump fuse, and crank while throttle plate wide open.

Report back after these findings.

badass8 · 09-05-2014, 01:39 AM

Were the "used" injectors flow tested? How did the seals looks on them? Seems as if the only real problem could be the injectors IF it was running fine before that.

Night drifte89 · 09-05-2014, 02:02 AM

Compression was 150 across, all have spark, #4 is Alil dimer than the rest. And they were not flow testes

Fuel pump on the way

Got a new fuel pump and the same issue. Dies when you push in the throttle. So idk. Once and awhile the check engine light turns on and then off right away. Kinda weird. And now my battery is probably shot so I'm going to buy a new one to rule that out too.
