like the title said, I jus installed my BC 272 and now the car has a hard start. timing seemed fine, everything is connected. Don't know whats wrong. Is there something i have to change ecu wise. plez help
thanx

 

double check your timing

 

Doublecheck the cam timing, when the gears line up with their marks on the cams, marks on the cam cover... then the crank should be "just before" the mark for most cars

you said it has a hard start, does it run or not?

 

doesn't run

 

its your timing i garuntee it

 

aiight thanx you guyz, ima go double check

 

I just put BC 272s in my car last week, installed by me and I have 0 issues. Like everyone has said already, you need to check not only you cam timing, but also that the crank and oil pump marks are lined up if you took the timing belt off and it happened to go loose.

 

make sure you reconnected the cam sensor or that it is not 180* off, that will cause the engine not to fire.

 

i didn't take the belt off, it might be the cam sensor, ima have to check that first thanx

 

you guys were right it was timing, car runs really strong now
thanx for the help
