I don't know what my sc400's problem is but everyday it will decide that it wants to take multiple mins of me turning it over to finally start. Right before it starts it begans to sputter and sound like its knocking than it will stay on by itself like its getting no gas than about two more attempts it will crank right up.

i have done the fuel pump "bypass" already and it still seems like its having a fuel problem any one else know what it could be from what i described???

also my tach and speedo dont always work they just stayed zeroed than about 10mins later of driving one will kick on. than about 5 more mins later the other will kick on. anyone ever experienced this???? its quite annoying, ANNNND the needles are burnt out!!! UGHHH!

 

Needles burnt out it sorta a regular on sc's. As for your cold start issue, I'd start by checking the plugs and see what they look like. And flow test the Fuel pump

 

how do i flow test the fuel pump???

 

OMG i filled up with regular unleaded twice.......... I FORGOT ALL ABOUT the premium gas thing...i will relay back to this thread after i put premium back in.... im sure the "dirty" gas is whats doing it.... i guarantee the fuel filter is dirty FAAAAACCCCCCCKKKKKKK! FML!!! stupid mistake!

 

noone has an idea of what the cold start could be???
