I have an 88 s10 2.5l 4cyl. Whenever I turn the ignition on the ECM B fuse blows. This is a major problem because as far as I can tell that circuit is for the fuel pump relay and the oil pressure switch. In a nutshell I have a no start condition because the fuse won,t let my fuel pump run. As a side note I have replaced the Oil pressure switch, fuel pump relay, and the fuel pump with no change.
