[WOOS1]

Several dumb questions because I am chasing a problem that could possibly be related. Is this module only in the heavy duty trucks? Ever offered in a full sized blazer? Just looking at the schematic, it appears that that pump should have still have worked after the oil pressure came up and the oil pressure switch took over the controls?? Just would have to crank the crap out of it to get it to start (which is what mine is doing....). Sorry for all of the questions, but I am stumped on mine and trying to understand the fuel system.
