Helpin a buddy out and I've little experience with Chevy TBI systems..
He's got a 92, 4.3l TBI .. daily driver, ran great until yesterday when he came out of the store and now it turns over but no start.
Noticed theres no fuel pump prime going on (cant hear the whine we normally do) when we first turn key on..
FP fuse under the hood is ok, but I measure no voltage to it.
I know the Ignition Module on these things likes to die.. are the ECMs on a truck this old smart enough to notice a dead IGN module and not bother turning on the pump?
Also, I keep getting mixed info on this from the google, IS there an oil pressure switch in the fuel pump circuit on a '92?
thanks for any advice you can offer..
