SOHC 97. Fuel pressure regulator is losing vacuum from 10hg to 2.5hg in 7 minutes. Is that normal ? What are specs for fuel pressure? My one runs with 33psi only when idle.

Truck runs lean. I am checking everything and put a vacuum pump on the fuel pressure regulator to check if it holds vacuum. It goes from 15 hg to 9,5 hg in 60 seconds! Is that normal? There is no fuel in the vacuum hose...

Hello there ! I have read some threads in here from time to time for tips on simple repairs & sensor replacements. I currently have the pleasure of replacing my FPR - fuel pressure regulator on my '99 Explorer V8 5.0 Yes, I know this part has been disco'd by Ford, but what's the...

Read a bunch of threads, and think I have this problem licked. The car has 230K on it and every once in a while it wouldn't start hot. I live in Vegas, so I attributed it to vapor lock. It always started back up in a half hour or so. When running, it was perfect. The other day it got cold...

Hello Ford Geeks, I'm new to this forum, so I'm introducing myself, as requested by the forum. I'm not a sporty, off-road motorist, nor Henry Ford throwback by any means-I prefer bicycling to driving on most commutes, and I wanted to find a Toyota Previa-AWD, before settling for the...

Is the FPR suppose to have a single vacuum line coming off of it that splits into two before the tree and thus has two lines connected to the tree? Seems like that would double the vacuum pressure or is the FPR suppose to run off that? Thank you for your time! :thumbsup:

94 explorer with stock 4.0 liter runs great when cold, after it warms up a bit it acts like it's out of gas when I push the accelerator down. Would the fuel pressure regulator be a likely suspect? I've replaced the fuel pump relay, the fuel pump, filter etc... this vehicle sat for 5 years...

Hey everyone, My engine will not start and I need help. It is a 2001 XLT, 4.0 V6 SOHC, A/T, 2WD The engine will not start apparently due to excess gas [massive “flooding”] So far I have found the following: It cranks strong, so battery, starter & ignition all work well. It has...

I'm hoping to get some input regarding the function of the vacuum line on the back of the FPR. I am having a problem with performance in that my truck will intermitantly bog down (happens more often when it is hot) and it will also backfire "cough" when I mash the accelerator at a stop...

little history, I buy a car with around 100000 miles for cash and run it till it dies. my caravan that had 220000 + miles just went on me, so not cost effective to repair. After 7 years of the same car I bought my dream truck, a 2001 Ford sport trac. looks awsome...or so I thought, the guy I...

Hello all, I have had my '99 Mountaineer 5.0L V8 AWD for 1.5 years now. Since I bought it, I have replaced: MAFS, A/C Clutch, 2 Front Wheel bearings, Front Pads & Rotors, Intake Manifold Gaskets, Fuel pump, Fuel filter, Idle Air Control, and PCV Valve and have done a rebuild on the front...

ok i've read this place enough to know that normal rpm's at idle are around 500 to 700....now that being the case, when mine get that low, my ex sounds like she's about to die, the lights flicker and the voltage meeter bounces around....cleaned the maf and cleaned the iac, plan on replaceing the...

ok here's my issue, in the course of tuneing up and working on the engine, i've broken many vaccume lines, so many that i dont know where everything is anymore, i do know that they would go to the vacuum tree, anyways the only thing's i have hooked up to the tree are the break and cruise, and...

Hey all, I was out wheeling at night and all was good. Once we got back on the pavement I tried pushing on the gas to accelerate up to speed (55mph) and it wouldn't do it. I pushed harder on the gas, and the engine's RPMs didn't respond at all. Didn't notice ANY problems on the "trails", but as...
