[size=10pt][size=10pt][size=10pt]Hello folks,
I could use some of your expertise. Now the vehicle in question is a 2004 V6 (3.9L) but I think the logistics with the fuel system are fairly similar to the V8's and I could use all the views I can get (things in V6-land can be slow).
The car ran fine, stopped at a store for five minutes and then would not restart (cranks strongly but won't catch). The FP fuse has been pulled and checked and has 12V on both legs when installed. All exterior and interior fuses have been checked and all have power (sans things like lighting items, which were not active during my testing). MAF is clean (I cleaned it a week before this happened [I do it periodical] and the car drove fine for the last week till today. I checked and touched it up again tonight).
I don't even know if these new fangled cars have a FP prime out (in reading your posts, it seems they do). The pump is NOT priming out. I kicked the tank, no help.
The Theft and CEL both prove-out and both are off while cranking. It has a pending DTC P1237 but I *might* have generated that myself (seems like disconnecting the inertia switch while the key is on might do it).
The car DOES have spark.
I cannot find a Schrader valve to test pressure. I checked the inertia switch and it was closed. Both legs show 12V KOEO.
At the FPDM, the pink/blk and brown/pink both have 12V KOEO.
I performed the two following tests I found online:

Voltage was 13.15V. So if that info on that page is correct, the FPDM is bad, no?
I also did the following:

When I applied 12V to pin 10 (I jumped power from the adjacent pin, pink/blk), and then grounded Pin 3, nothing happened.
So the former test suggests a bad FPDM and the latter (if valid) could suggest a bad pump. I'm gettin' confused.
Any thoughts are greatly appreciated![/size][/size][/size]
