So... I have a 91 k5 that is really making it difficult to diagnose my problem. It's been running just fine then suddenly I drive it to my local HD park it , go inside come out to start and it won't. Turns over fine but no start . Towed home poke around and I'm getting spark but no fuel . Spray starting fluid and it starts for a second. Have replaced fp relay,fuel pump,oil pressure sensor ignition module, fuel filter and nothing. I do not have the CEL light on when I turn key forward....what next please!

Figure out why the CEL doesn't work.
Hard for me to dela with this stuff here, but perhaps the electrical or service manuals are here: http://67-72chevytrucks.com/vboard/showpost.php?p=5621043&postcount=1 No CEL is going to be one of the very first diagnostics. Could be the bulb, could be something else. First step is to make it work.
'87-91 are essentially the same wiring, but the instrument cluster changed quite a bit in '90, as did the way VSS was run. Best to stick with the proper year, when possible.
