What could cause my Chevy 5.7 350
throttle body to run good for a while then
just die. Fuel pump is putting out fuel
Filter is clean new spark plugs and wires
and clean injectors

1 Answer


It may be the Ignition Control Module in the distributor, if you take it out and take it to Auto Zone, they can test it. If you do that, might as well bring the coil along with. Now this is not to say that there isn't a fuel issue going on either. The fuel regulator could be weak in the TBI. Fuel pressure would need to be checked to verify, which should be 9 to 13 lbs. If it is not I can tell you more on what to look for with the fuel pressure.
