Message	That was my diagnostic after swapping the controller. I tapped a voltmeter in to the leads directly on the fuel pump (or on top of the pump as the case actually is) and drove around watching the voltages. Everything was normal. At WOT the signal voltage drops to .6V which = battery Voltage (13.5V) - (0.6V signal) = 12.9V across the pump. Exactly as expected. The stock dampner is still in place. I wasn't sure if that could be removed with an aftermarket FPR or not. So can it be taken out? (less parts = good in my book) Meddle not in the affairs of dragons, for you are crunchy, and good with mustard.
Follow Ups	Fuel pressure drops under boost. Any thoughts? (detailed) >> - Greg (Dallas) 09:21:24 09/27/02 Have you checked for boost leaks? How is the gas cap? - wcoffey 09:29:43 09/27/02 Gas cap is good. Question on boost leak tho >> - Greg (Dallas) 09:49:16 09/27/02 As far as the boost leak, I had a large hole (dime size) - aZiator 10:40:59 09/27/02 Yeah I can understand that BUT >>> - Greg (Dallas) 13:18:39 09/27/02 I have a huge boost leak, but still can get full boost. - wcoffey 10:49:05 09/27/02 All fuel temp sensor does >> - Greg (Dallas) 15:25:11 09/27/02 How about the Fuel Filter? Do you have an OEM around???

(n/m) - Carlos Ramirez 21:17:34 09/27/02 have you swapped the PVR sinanoid?(SP) seems like that's - Halo Z 12:56:13 09/27/02 Yeah, swapped as in ripped it off and in the garbage. :-) >> - Greg (Dallas) 13:13:18 09/27/02 haha. (n/m) - Halo Z 13:33:56 09/27/02 Measuring fuel pump voltage shoulddothe same, BUT - Chip(GinnMotorsports) 13:21:07 09/27/02 No, but here's more info (after testing today) >>> - Greg (Dallas) 14:27:39 09/27/02 Mine lost fuel pressure at ~1 psi boost. - Chip(GinnMotorsports) 14:49:47 09/27/02 Just a thought... - CatDaddy(OKC) 16:40:07 09/27/02 I've looked and haven't seen anything obvious. - Greg (Dallas) 16:47:49 09/27/02
