Just wanted to give forum member JustDennis a BIG THANK YOU for going out of his way to help me get my car running. He's stopped by my place several times to advise, tinker, WORK, & scan the various systems with his Tech2 device. He's been a BIG help. Can't thank him enough.

The 3rd Friday afternoon/evening of every month there is a "Cruise" night at the Court House Square in the center of town. Inverness is in North Central Florida ~20 miles west of I-75 at the northern end of the Florida Turnpike (Wildwood, FL). City of Inverness Webpage ... Friday Night...

I tried to remove mine but was unable. Once you remove the battery there's a square hole in the bottom of the battery tray. On the vertical sides of the square hole are 4 bolts. I removed the 4 bolts but the tray wouldn't lift off of the mounting base. I didn't see anything else holding the tray...

I measured the resistance on mine with my ohm meter (DMM) and it shows good but I couldn't flex the wiring harness to the ground point to determine if the wiring was OK or not when the car was in motion. I also took mine apart and found no issues or corrosion but I'm still wary of this ground...

Something you might want to check is the ground point at the rear of the car on the driver's side behind the rear wheel fender liner. This is the ground point for the Fuel Pump Control Module (FPCM). I've found posts regarding problems with this ground point. Separate it and clean it, remove any...

Dennis, see the thread in this forum... https://www.cadillacforums.com/threads/ecm-commands-to-fpcm-help.1142280/ I think this guy knows a little something. Doesn't answer my question about the "Off" state to the Fuel Pump but it's leading in the right direction. Rick

For some reason my Fuel Pump Control Module (FPCM) output is driving the power to the Fuel Pump Electric Motor into an "off" or disabled state. Does anyone know if the ECM can command the FPCM to place the Fuel Pump in an "off" state? My budget service manual doesn't cover the Fuel Pump System...

Hmmm... I thought I was awarded a trophy on this forum. Must have been on a different forum. Sorry for the trouble.

How do I award a trophy to a member?

First get a Fuel Pump Tester (gauge that attaches to the Pressure Relief Valve on the Fuel Rail). They're not expensive and readily available. Confirm that you don't have fuel pressure when the car won't start. If you have fuel pressure but the car isn't starting it's NOT the Fuel Pump "System"...

According to my budget Service Manual for the XLRs your '06 doesn't have the Fuel Pump Control Module. The Fuel Pump on the '06 & up cars is energized directly from the Battery through a relay. The relay is in the Fuse Box under the hood. This is the same method for powering the Fuel Pumps in...

When I removed my mufflers I didn't mess with the crossmember. I did remove the rear sway bar. But I separated the exhaust pipes at the exhaust manifolds (at the engine) before trying to separate the mufflers/pipes at the rear. This made it much easier to separate the muffler pipes and twist the...

I need to replace the Fuel Pump in my '05 XLR. For various reasons I'd like to "upgrade" it to the '06 - '09 Fuel Pump. The '03 - '05 Fuel Pumps are operated at multi-speeds through a modulator (FPCM). The '06 - '09 Fuel Pumps are operated at a single speed through a relay connected directly to...

You're referring to the Water Outlet Housing. I just removed mine in order to replace the Bypass Hose. It's easy to remove. Drain the coolant, remove the intake snorkel, remove the EVAP Purge Solenoid, the MAP sensor connector, the heater hose to the 2 threaded fittings, remove the Throttle Body...

So I had to replace the Water Pump on my car and I got a shock when I discovered that the housing mounting bolts are high carbon steel. After 20 years I would have expected steel bolts to have fused solid to the aluminum engine parts but not so. The bolts can't be bare steel or they would have...
