Just because it isn't FCP Euro doesn't mean its counterfeit injectors.

Go to the shop and tell them to change em. I’m pretty convinced my injectors are leaking a little bit too. o2 sensor fault code hasn’t come back. I just replaced plugs, coils, and fuel vent valve and issue is still there. Walnut blasted 5k miles ago and a bunch of other stuff done as well. It probably leaks a little after shut off as you eluded too earlier, and eventually evaporates which is why cold starts are normal (for me at least).

I didn’t mention FCP. There are many places where you can buy authentic injectors. Fact of matter is that you purchased injectors with unknown origin and have repetitive issue. You came here for suggestions. I gave you one.

I never came here asking for suggestions related to injectors. You felt the need to express your own opinion. If you have nothing to add to the original issue then no need to comment.

lol dude! You #1 post ends with “any ideas?” but hey! Is ok, no more comments. Good luck.

Well if you get new injectors to be sure to get them from FCP Euro. The only trusted place to get them.

I will have new injectors next week so we will see if that does it. If I get a borescope down in the cylinders again I can post them here.

Update..

I replaced injectors with new index 12. Car still does long crank.

[Boosted12a]

Can mhd do logs during start up? Maybe see what the fuel pressure is during the long crank?

Yeah I will get another one with new injectors. Fuel rail will get 2k+ before it starts.

It is an option. I am not sure how to test that.

Not sure which, but some scan tools/apps can monitor and log it.

[Boosted12a]

But why dose it start fine on cold starts? I would think the longer it sits, the longer it would take to crank?

[Emilime75]

Oops, never mind then. I'm way off.

Editing my previous post in order to not lead others astray.

Yeah, the LPFP sensor reads ~72 when I turn the key on (LPFP primes) and it holds. When I shut the car off, it even stays in the ~72 range.

I wonder if anything electrical is causing the injectors to maybe stay somewhat open. Or maybe it isn't even fuel related. I am going to do some stuff tomorrow and see if I can figure something out.

Strange thing is, after I put the new injectors in I got the car warm and let it sit for 30 minutes. It started up just fine when I tried to start it. Before the injectors it would long crank. Then I did it again but about 1.5 hours later and it started fine. But then the next day it went back to long cranks.

I was just watching a vehicular diy vid. He mentioned the fuel pump module can cause long cranks cause it gets hot. Maybe something to try?

The EKMP? I am not sure. They controls the LPFP. And when I get in the car, the LPFP is primed and the pressure doesn't change.

Honestly the best way to diag a long crank is to connect a fuel pressure gauge to the low side fuel system and see what it does during cold start. That's really the only way to eliminate the low side fuel system.

My car does it sometimes, I just blame it on the e85 blend.

I would just figure if it was the low side it would do it on the early morning cold starts as well.

Update. Was doing some digging around and found that one of my PI injectors was stuck open. Stuck borescope into manifold and seen fuel at the tip of one of the injectors. Also found a little bit of fuel in the chargepipe. I will update this once I drive the car a bit more and see how it does on warm starts.

PI injectors?
