I just had a BFO.....yea, I'm very senile. One of the things that the CCM does is house the VATS system. The VATS system is just an electronic switch or relay for the fuel pumps. That's what keeps the bad guys from hot wiring our cars. No key pellet ; no fuel. You hear the pumps right? Just humor me as an old guy who's senile...
....Hook up a fuel pump pressure gauge to the rail. Drain off the built up pressure thru the dump, and then go put the key back in and turn it to run and observe the gauge. Sort of like the start of the fuel pump diagnostics KOEO test flow chart in section 6E. If you got F-pressure, the VATS & key & possibly key cylinder wire are all okay. I think that diagnostic thought train is valid.
