fuel injecter or fuel pressure regulator ?

mtnmiller · #1 Jan 1, 2007, 01:43 PM

I have a 1996 gmc sonoma (zr2 package) with a 4.3 motor (engine code W). I sometimes have problems getting it started, when the motor is warm it starts without any problem, but when it is cold i have a hard time getting it started, if i put gas or starting fluid down the throttle body it starts right up. I have been told that this could be either the fuel injector or the fuel pressure regulator. Would appreciate any help.
