Having a fuel delivery problem with my 94 S10, so in order to affect proper diagnostics, need to find out why no check engine light present in instrument cluster. I have the cluster out of the dash, and have googled some views to locate approximate spot it should be located. Printed circuit array on back of cluster offers no help though. Thought maybe with the appropriate wiring schematic I might locate a missing or burnt out bulb.
This is a 2wh eel drive PU with the 4.3 Liter "W" motor. Commonly known for fuel pump problems in this transition year, I have already addressed pump replacement, relay and harness integrity, and now attempting to perform scan diagnostics, but unable to ascertain why no check engine light appears in cluster array.
