could it be something with EGR not closing properly making u go lean? don't know if your EGR is deleted or not. I think i saw Enki say it but an exhaust leak could also cause a lean at idle, check for cracks in the accordion on the EM

Do you get any codes when it happens?

the signal wire is which one, i tested the circuit from the connector to the ecm connector for 2 of the wires and less then 2 ohms. I will do the last one tmr i needed to find which pin corresponded to it. I also tested from the connector to ground and my test light lit up. So is the signal...

so i tested my fuel pump resistor with a test light and while cranking had the clamp on a ground and put the test light on each wire and it lit up so Im assuming the resistor isn't the problem. Fuel pressure is still 0 so where would i buy a new sensor, I was reading that its a discontinued part

Yeah I know all of that, the engine does shutoff. I think it might be 2 separate problems unless the fuel pump resistor would affect the reading for fuel pressure but I doubt it

So my mechanic(uncle) that fixed my car came over today with his family and we checked out my car quickly. The fuel pump resistor seems like there’s a problem there when he shakes the connector and moves it around the car acts differently but it still reads 0 psi fp so I’m going to get myself a...

I posted a new thread seems like there’s a problem with the fuel pump resistor

I tested with no power so no key in ignition, the connector was soaked with something not sure what. I didnt check end to end I had to find which wire it was going into the ECU. Will the headlamp connect directly into the connector for the FP sensor? Thanks for your help

So I’ll make this short, 2013 speed 3, 144k km. Just got a new ecu for an injector problem now I’m getting 0 fuel pressure EDIT: for anyone diagnosing fps issues, brown wire is ground, white w/ green stripe is the output signal and yellow is the input signal (5v) p0089 and p0192 engine starts...

Welp my cars broken down on the side of the ride with a p0192 lol. Couldn’t even drive properly for a week. Seems like my hpfp is dead

Yeah i mean my accesport sorry, autocorrect. thanks i think it would be a good look they might rub the road tho lol

i will need a new engine but Im going to wait till summer time to do that, my valve guides are leaking a little bit so thats part of my oil consumption but for right now it runs decent, Idle is really low because of stock tune but ill put a tune back on in 2 weeks As for the tune he just said...

Its fixed, it was the ECM thanks for all your help. He told me that it could have been because of my tune, tunes hold the injectors open longer and could have causes it to damage the internal circuits in the ECM. Either way i need to get a new tune from justin because my accessory has a...

It will 100% fix my problem it was running good before, leak down is 25% at worst in two cylinders I can get through the winter with this engine and save for a built motor in the summer.

Your right u didnt say ECU but it is indeed 2 injectors down sorta I just hope that they tested all the wires properly and the ECU does actually fix the problem, this whole thing is like 99% sure because of the p0202 code i had must've damaged the circuit or smt

What? yeah he did it was on the first page pretty sure but there was no way for me to know that without checking everything else

my mechanic said best way to fix the ecu would be to buy a refurbished/used one and he's able to reprogram it with his scanner apparently will only take an hour or two Maybe the first owner but I couldn't tell you. I know that they saw the voltage drop on the waveforms and it was a super...

I just asked him if he load tested the harness and he said he did it with his AVR and it checked out, not sure what AVR is tho

Finally reporting back with what the problem is! So on the waveforms the injectors on cylinder 2 and 3, the voltage drops and doesn't hold at 60v which is why it goes lean and my fuel trims are crazy high. Now they tested the wires leading from the injectors into the ECU and the resistance is...

I did unplug it since the problem started i think i did it twice but i can ask them if they've done that. i know they've reset it from the scanner but thats not the same as physically unplugging it I would assume I was reading up on ecu failures, im thinking if it is that maybe its the ignition...
