Long Crank

BMSE92_Harry · 07-06-2017, 05:47 AM

My car was cranking up just fine before Port Injection, after MMP install and added port injection, the first crank at cold start takes 2-3 seconds to turn over. But if i shut it off and crank it again right after, it starts right up.

Any idea why it is doing that? HPFP and LPFP on logs look fine.

i too am getting long crank with mmp pi added but i think its because of me running straight e85.

Check your port injectors. 2 of mine where leaking with the car off. 1 drop every few min .

Is there another way to check them beside pulling the intake manifold again?

how is your warm start after letting the car sit for 30 min to a few hrz ?

Start up just fine on warm start. Just the initial start when the car has been sitting for couple hours or so.
