Hi Scotty, I have a 1999 Chevy Blazer, had an issue where the wiring harness shorted out under the ABS module, fixed that but now it wont start. It just cranks and cranks and never turns over. All the fuses are good, the fuel pump hums along, I get spark, starter fluid does nothing either. I've heard that the issue could be the passlock system, but I don't get the SECURITY light, and it seems that passlock allows the engine to run for a few seconds whereas mine never turns over. any thoughts?
