So I just bought an evo ix with a bent valve.. I got the head rebuilt and got the car back together.. Everything is good and it's running good besides the start up..
It takes like 10 seconds to start and I believe it's not keeping fuel pressure when I turn it off but idk. The car didn't do this before it broke down either.. There is pressure at the fuel pump.. Also the wideband is reading lean and staying around 14.2 and 13.2 at wot only 14lbs.. Car was running 25psi on stock ix turbo with walbro fuel pump and basic bolt ons. Made 350 whp at one point with all the same mods.
I may have a very slight exhaust leak at the down pipe to maybe throw off the wideband.
Thanks for any help

 

I think one of the injector seals is shot. I'll replace tomorrow
