Well like the title says, put the car back together and no fuel pressure. wondering if anyone around has been through this or could help me out. 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
Have power to injectors, cops, etc.

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?

When you get access to the CCRM back probe the Green/Yellow stripped wire to see if you have power going to the FPDM. When you turn the key on you will only get power for a moment . It dosen't have constant power unless the car is running. The CCRM sends the signal to turn on the FPDM which in turn operates the pumps. If you have power at the G/Y wire then the problem is not at the CCRM.

Did you reconnect all that wires that you disconnected for the swap? You should have only had to take off the COP's and the injectors. During the pump swap did you disconnect any other wires besides the two pump leads?

Did this help or did you already find the problem?

Oh and another thing, you said that when you turn the key that your fan comes on? That is a indication that your PATS is activated also, check to see if your thief light is still not blinking when you turn the key. Just another troubleshooting idea. It did that when I did my conversion.

well i jumped the fuel pump and out pressure on the fuel rail. turned the key and the car started and ran until there was no more fuel left. so the pump and cam install are good. i checked the green and yellow wire coming from the ccrm and there was no voltage when the key was turned. there is voltage from the battery and everything so i'm guessing its the ccrm.

but here's the kicker. while messing around with the ccrm i think i accidentally grounded it and put current on it, sparks and all. well now, the car wont run if i jump the fpdm, and when i try to read the codes, my SCT saus unable to read codes. Went to tune and return to stock, and it said there was no vehicle attached. WTF? did i somehow manage to fry the cpu?
