I recently installed the zzp stage 2 kit with 2.9 pulley and 60 injectors.I do have the proper supporting mods as well , head\downpipe, 2.5 catback, heat exchanger . I installed everything properly. Car starts but won't idle. I have to feather the pedal to keep it going. It also sounds like I have a misfire as well. I plugged in an obd2 code scanner and won't read the car. I have the canned zzp tune . Any ideas? Thank you

 

Do you have a wideband? Whats that reading while its running?

 

id bet you have a vacuum leak. re-check everything you did, vacuum lines and the gasket between the blower and manifold. also check the air intake connections, and throttle body gasket. dont forget about the injector o-rings. if your sure everything is good, contact zzp.

 

This. Def check to make sure your injectors are seated correctly in the head as well.

 

did you plug in the tb connector ? its the hidden one on the bottom of the tb

 

He said if he pedals it it stays alive

 

mine stayed running it just ran lik **** and threw codes. Its just one of those things you cant visual see so i suggested it.


i would go with a vac leak though. .... do you have a boost gauge ? what the vacuum at idle ?

 

Thank you for replying guys! I really appriacate it every thing. I'm going to rip off the blow and visual inspect for an Leaks .

 

Hey bro idk what year it is but mine is in the shop now for a fuel pump replacement it's doing the same thing yours is and mine is stock they said they would do it for free too because it's a reoccurring problem with balts. I'd def check it out

 

It's a 2006 and thanks man I have to consider that I just got it towed to a local shop , hopefully they can diagnose the issue. Team recall lol

 

UPDATE It wasn't my fuel pump I had a rusted hole in my fuel line $1100 dealer fix

 

**** that, make your own lines way way cheaper. Even going full AN with PTFE lined it will be cheaper, including an outer weather proof casing

 

Agreed!

 

Would have! ....but it broke more when they were diagnosing the pump. I just said eff it it'll at least have a warranty with it plus I don't have time to drop the tank and run it seeing as I don't have a jack or stands

 

Wait...they broke the lines? They should be comping at least the labor if they caused the issue. If the lines were already broken you would of smelled fuel when you tried to start it and keep it running. The lsj stock system is like 58psi which if the pump is good then it doesnt take a large hole to dump fuel out

 

It was a real bad fuel smell and I had lean codes out the wazoo.. it just split more when they took it down.. They didn't know it was a fuel line problem they thought it was fuel pump related

 

Figured out the issue ! I installed the fuel injector harness backwards. Now car starts and drives fine , but only seeing around 11psi wot !?

 

Here we go again...
