Well like the title says, put the car back together and no fuel pressure. Here's where I'm at:
Went ahead and replaced fuel pump (140,000 miles on original) with SVT focus pump - with key on, jumped hot to pin 10 on FPDM harness and the fuel pump kicked on, so everything is good between the FPDM and the pump. Also checked harness to fpdm, no voltage when key is turned on. So I think the problem is upstream of the fpdm.
With key on, checked fuel pump wiring harness - had 5-6V on the two outer pins, nothing in the middle - What does this mean?
Have 12V across battery (sanity check)
Have 12V coming out of main engine compartent fuse box
Checked fuel pump fuse, it's fine
Checked rest of fuses, all fine
Checked for voltage coming out of the fuse box, had 12V solid
At this point, I'm wondering if I have a bad CCRM? The fan kicked on for no reason last night while I was doing tested and I know it's part of that system. To check the CCRM I guess I have to pull the wheel off and the fender well guard. Once I get to the CCRM, does anyone have some guidance on how to check it out?
