N55 starts then dies

JCip91 · 10-13-2018, 04:40 PM

I have been having this issue for a month now and I have tried everything I could but now I need help. Just as the title says the car will start up idle for a little bit then just die. No codes either. Some times it will start and idle fine but as soon as there is a load on the engine, like revving or driving, it will misfire then die. I replaced the HPFP twice, the EKP, tried jumping the LPFP and checked the two fuses for the pump and nothing is helping.

My car have a jb4, e85 backend, cat les, and has a stage 2 lpfp.

Any guidance or advice is much appreciated!
