throtle body problem 350 chevy engine

tom63b · 07-20-2008, 07:53 AM

i have a chevy 350 motor with a throtle body syestem on it. the throtle body is only goving me one pulse of gas. instead of a stead pulse like it should. we have already changed the distribuiter and it still only gives us one strong pulse. what do i need to do to fix my problem?

Are the fuel lines clear and not collapsed anywhere? Is the fuel pump working at the prescribed PSI for your engine? Is the fuel filter clear?

don't understad why you would change the distributor...to fix a fuel supply problem...what year is the vehicle...or motor if not OEM to the vehicle...usually fuel pump is located in the gas tank...and is electric...fuel filter usually in-line...and a metal canaster...i'd be checking the vaccum hoses going to the throttle body...could be loosing vaccum through a vaccum hose that is cracked...aged and lost its ability to hold vaccum...
