I recently fully upgraded my fd to a single gt35 turbo. It takes about 5 to ten minutes of off and on cranking before it starts slowly...then once its warmed, it starts easily. I have a 255 walbro fuel pump. 550 primaries and 850 secondaries.
sometimes i have to unflood the spark plugs.....
Does this have to do with compression? need help?

thanks

 

what engine management?

 

Your only running 850's for your secondaries??? You must have ***** of steel!! Upgrade those secondaries ASAP!!! And ya what are you running for ecu. You might of fouled your plugs. Take them out and check them.

i have aem ems...

 

check you initial pulse start fuel enrichment... it seems you are getting to much initial fuel add on.... i had a similar problem, starts and see a whif of black smoke

hot start is it alway ok? or is it a bitch to start?

yeah hot start is easy , if it sit for a while then it's a bitch ...

 

seems to me like a leaky injector....

have you got them serviced recently?

 

If you need some help to fix that hick up, on the FD just holla!

 

If it had low compression it would be a bitch to start when warm, so that is good :-D
Linky injector's are way more $ than an engine.

 

yeah i've been having similar problems.. i'm on haltech ems. 720/1600s, the injectors are new i don't think they're leaking but i'm not positive how to check?
