on soo i have a s4 t2 with a new engine streetported and no emmisions everything blocked off with 3 mm seals stock ecu , with safcII,

ok soo the problem is that wenn i start my car it takes forever if it starts, i have plenty of fuel plenty of spark, i have a feeling it might be a dirty injector or somthing
it starts but the engin soars to like 5k durring the cold start then goes down to 1100 and revs to 1500 like a (big cam) in a v8, after i shut it off it wont start back up again it will crank over and wont even atempt to fire,



any sugestions

i think its ether timing or injector failure

 

Make sure the water thermo sensor on the aft side of the water pump is connected up.

 

i have i went over the engine bay 3 times for plugs and stuff missing
