I tested the fuel rail pressure per above post. The engine is flooding with fuel. I'm trying to figure out why. Code P0190 appeard after the engine started to run poor. I'm trying to dtermine if there's an underlying problem that caused the code or is the SVT focus pump just going to work right...

Thanks for the replies. The fuel filter was replaced at the same time to pump was replaced. I've determined that the engine is getting way too much fuel. Below is my latest correespondence with member wmburns in another forum..... wmburns: Have you confirmed that the intake vacuum reference...

Anyone else care to chime in ?

Mike....thanks for the reply. I checked the alternator & output tested good so it's been ruled out. @ evolucion......I too would like to hear an educated response to your question. If I understand it correctly, the FPDM acts as a voltage regulator by supplying variable voltage to the fuel pump...

Thanks for the reply Burns. It looks like you're the expert on here for fuel systems & just the guy whose expertise I need to help me save my sanity. I never had a problem with this car until it sat too long & the battery went dead. Was it a mistake to install an SVT focus pump instead of a...

Ok....now I'm frustarted. I replaced the fuel pump with the Focus SVT pump. I turned the ign. on , heard the pump prime & the car started right up. I let it run for about 20 minutes & it seemed to run normal. I turned it off & let sit for about an hour. I started it up again & was running like...

Anyone care to take a shot at this ?

I Have a 2001 GT with a Diablosprt custom tune installed. Does anyone know if the custom tune parameters can be changed by me using the handheld tuner rather than to have the custom tune modified by the shop that wrote the tune ? I have to reinstall the factory catted mid-pipe for inspection &...

I used a battery pack to supply 12v to fuel pump harness connector RD/BK & BN/PK wire terminals per the posts above. I'm planning to order the SVT module PFS-204 & use just the pump only. Does anyone know if there are any modifications required for the proper install or does the PCM require...

First off....thanks everyone for taking the time to reply. The diagnosis is a bad fuel pump. The replacement OEM Motorcraft part # I've come up with is PFS-170. It's for a complete module assy & runs in the $300.00 range online. The dealer wants over $500.00. Is it true that a replacement...

Hi all......I have a 2001 Mustang GT that has been sitting for a long time....roughly a year. I generally try to start it about once a month & let it run for a while or take it out for a drive (I work a lot). I've been reading through these forums recently & there definatley seems to be a...

I recently had a local performance shop install 4.10 gears & a master bearing kit on my 2001 Mustang GT auto. There is a noticable "whoob whoob whoob" noise that can be heard upon decelleration only. No noise is present when accellerating or cruising. What's interesting is it's really pronounced...

If you have the extra $$$....Mobil 1 can't be beat. Motorcraft 5W-20 is the reccommended oil & it's certainly cheaper. I run Mobil 1 5W-30 in my mustang & Motorcraft is the wife's Ford Ecape. When in doubt, go with what the manual says !

It doesn't sound normal to me if I'm understanding you correctly......may be time for a replacement !

The tensioner on my 2002 GT sometimes moves back & forth. It's an intermittent thing that I've noticed. It has improved since installing Steeda pullies. Prior to replacing the pullies, the serpentine belt would actually run against the timing cove under heavy throttle. A new belt may remedy the...

Thanks for the info......anyone else ?

After going back & forth on several different lowering springs, I decided to go with Ford's "B" spring. My question is regarding the actaul drop to be expected. Based on numerous photos of other mustangs, it seems that the "C" spring tends to drop the front a little more than the "B" spring...

Appreciate the information guys.....I'll p/u a new belt & give it a try. Thanks again

I guess this is a fairly common problem on our cars. My GT only has 19,000 miles on it & the belt looks brand new. I suppose looks can be deceiving. I can understand the belt slipping, but why deflect to the point it moves side to side as opposed to up & down ?

When running at wide open throttle, there's a pronounced squealing noise which sounds like your typical engine belt squeal. It seems to last for about 2 seconds then goes away. It only seems to do it when nailing it from highway speeds after the rpm's get to about 5,000 rpm's. While lookin under...
