It's actually an evo 8/4G63 that keeps blowing up, I think he's cursed honestly haha.
I agree 9K, I'm currently boosted on a remaned engine I'm going to give this hell until it goes and do a solid rebuild and then swap for another power plant.
I bet the swap/Frankenstein section fills up with build threads in the next few years.

Okay, so I all of teh sudden starting having long cranking times. I have a new battery, brand new series II starter, and I just compression tested last weekend and all is good.
Well, I think I norrowed it down. I though previously when I turned teh key to the on position that my fuel pressure went straight to 60psi. So to confirm this I asked Paimon and Houstonrx8er to confirm since they both have fuel pressure gauges. well both of them confirmed that pressure does build instantly when the key is turned to the on position.
Paimon made a video:
And here is a video of mine:
I have a BHR fuel pump assembly that was purchased about 16,000 miles ago. So should I just replace the pump itself or do you guys think this issues could be something in the assembly or something else? I have access to the pump from an 09' R3, I may just swap that in. I have no fuel pressure issues while driving, it stays at 60psi, even under boost and AFR's are fine.

Yeah I was thinking an air leak as well. The blue vacuum fuel line seems fine but I guess it would not hurt to pull the UIM. Not sure how the resistor works, but I was thinking something electrical as well. Of course swapping pumps would tell me too, I have a few stock pumps laying around.

Interested to hear outcome as I think I've been having a similar issue but don't have the fuel pressure gauge installed (yet).
Noticed my Walbro pump was sounding a bit .............. rattly . Cranking times increased around the same time . Now pump has gone back to its usual whirring sound but cranking is still longer than it should be .
Have taken to letting the pump run until it shuts off then cranking - which seems to help.

Yeah it only does this after sitting for a bit. If I start it, shut down, and then start it again the pressure is built up so it fires right back up without delay. It's only when it sits for a while that I get the long cranking times. I will investigate after work.
Edit: never mind, duh.
