back in Texas....and for the fuel pressure is not rising...i have Wideband 02 and EGT gauge that confirm both. i just need to know reasons on how an FMU would break. to much pressure? a leak ? what?
edit.....the last FMU has been in my car for about 1.5weeks.

I want to know if it ever WAS rising. It may not be the FMU's. You could have a different problem. I think your fuel lines would blow before your FMU no matter the pressure. But if your fuel pressure NEVER rose like it was supposed to...something tells me the FMU wasn't the issue.

yeah at RRM when we hooked up a FPG it never rose....then when we chaged the FMU the pressure rose. witch told us it was the FMU....but now this one has gone bad. if you have any idea on what id should check let me know....cuase it might not be the FMU breaking but somthing to cause it to break.

That's what I'm thinking. If a part fails once..maybe twice...probably poor construction. But more than that and there's definately something else causing it to fail.
