I had just switched off my previously perfectly starting engine to go get some wrenches to adjust fuel pressure regulator. A moment later, I turn the key and get absolutely NOTHING.. no idiot light, no starter, no fuel pump....

If there is a significant blockage to flow for the fuel pump, would that kill some "master" fuse so I have absolutely no power? Pump was only running literally for 10 seconds. The front end is on jack stands so car isn't level. I know somewhere is a switch that kills the fuel pump if you wreck.. is this a mercury bubble type?

I've never had any problems with my ignition switch of any sort before.

No puffs of smoke..nothing...

I installed the engine about 10 months ago and at that time scuffed up the transmission ground really well on both body and transaxle. Has started reliably and strongly ever since (new battery at that time also).

Tonight, the only things I did were:

1) reinstall head temp sensor (engine started fine after that)
2) reinstalled air distribution manifold for smog (in way of head temp access)
3) remount (was never disconnected) the MPS to body (in way of head temp access)
4) Open fuel pump door in front trunk to pull out fuel pump and hoses (in case of kinks)... made wiring connections tighter at spades and left it lying in trunk.

engine successfully restarted after all these things I 'touched' tonight. Then killed ignition, when to get wrenches, and the "Dead" situation...
