Brz won’t start after fuel injector upgrade
 

I have a 13’ brz with JDL turbo kit.

I upgraded from stock pump and injectors to a dw65c and ID 1050x injectors. I also bought a ecutek with a tune to match the injectors.

Installed the pump and started the car, idled fine.

Installed the injectors and like an idiot started it before I loaded the new tune. It ran for a sec and shut off.

I installed the injectors and loaded the tune. Now it will start but won’t idle.

Pulled the plugs and they looked horrible (changed them like 50 miles ago)

Cleaned them up and it’s still doing the same things. Can anyone point me in the right direction? I’ve checked all connections, fuel computer is grounded etc.

Injectors are used, but seller had them flow tested and sent me a photo

Thanks. This is a new issue. Tune is fine. Should I be posting still in the previous topic?

They're related, in my opinion. Especially if your plugs were nasty in such a short amount of time, the tune must have been awful.
Put your foot all the way down on the gas pedal and crank it for a good 5-10 seconds. Do that a few times ( with maybe 15 seconds of rest between each session) and then try starting it with your foot off of the gas pedal, see if it's any different

I tired clear flood mode. it doesn’t crank, but just fires right up then won’t idle

I definitely flooded it when I started it with the new injectors before loading the tune for them
It spit some fluid out of the exhaust…

Do you think I destroyed the almost new plugs?

Also, if I keep the rpms up it runs, soon as I let off the gas, it’s over

Sounds like tune is not fine, that or there is an issue with injectors. My money is on the tune.

I’m new to ecutek. If I start a log and start the car and it idles for a second would that be enough for Delicious Tuning to see what the issue could be?

It can't fire up when you're in flood mode, that's the whole point of it. I would take this discussion to Delicious Tuning, keep bothering them until they can make it right. I doubt the plugs are destroyed, just wet. Hit the tips with a butane torch to get some of the crud off, if you're worried about them.
My only other suspicion is your MAP sensor. Is it stock, or upgraded?

I’d start with having them verify the injector scaling.

One thing I just thought of that hasn't been discussed in any of your threads on this problem is checking that you have the bottom mounting bolt in place for the Injector ECU. It's on the passenger side of the car near the port injectors. Once in the past I failed to have that bolt in place and it made my car run like crap. The bolt is part of the ground loop I believe. You should check this.

Unfortunately, he said this in his first post in the other thread :( good call out anyway

I removed the plugs and thoroughly clean them still still wouldn’t hold to idle. Batteries pretty dead now, so I just had to go grab a charger.
