Hay Allan, Thanks for the detail Input. I realized how much you love the rover gauge…! 😉. My USB cable is arriving on 14th for the rover gauge. Still looking for a 390 or 400 ohms resistor. pls tell me more on how do a test fuel pressure regulator? I don’t have a gauge. Specially fuel...

Hi guys good day, I have checked the Engine temp sensor and the fuel rail pressure sensor, following are the reading, Reading engine temp sensor Cold without start Eng off 1.58 ohms Start Eng dash at gauge 30% 0.47Ohms Start Eng dash gauge 45% 0.30Ohms Running for few KM’s Viscous fan on...

Btw, I have already ordered the USB cable for the rover gauge. Is it a must to install the 400 ohms resistor on the cable to get it work ?

Cool. Will check that this evening when I back home. Will update soon.

Hi, few more readings from MAF which I missed in the last post, Idle CO mixture adjustment Red/Black Blue/Red Idle or with ignition on the reading is same 1.87 Also reading from air flow signal, as switch on the ignition its shoots to 0.64 and settles back to 0.24, does this means that the...

Hey Allan, Thank you very for the information shared it was very helpful really appreciated. I have done the test and following are the results. Mean time I have ordered the cable for the USB FDTI cable for the Rover gauge, will be working on that soon. Reading from MAF, Red/Black -...

Oh okay. I was checking with the ground from battery.

Hi, thank you for your input. It’s a V8 3.9 no catalyst Hi, thank you for your input. It’s a V8 3.9 No catalyst. You said (ground from ECU) where do I find that ? In parked, full throttle I see black smoke. Also I feel lack of power. Note: recently I have replaced the engine, since then...

Thank you for the input, the issue connector was connected other way around. Following are the readings which connected and on idle speed, Wire color Red/black 0.06 Blue/Green 1.64 Orange/Brown 13.7 Blue/Red 1.94 Kindly advise if this...

Correct mate… it’s on total limp mode with black smoke fuel consumption was very bad and no power as well. I found the issue, when I replaced the engine the garage guys broke the MAF connector harness, now this can be connected both ways… so it was connected on the wrong side. Now I am getting...

You mean to disconnect the MAF ?

Hi guys, anyone has experience with discovery 1 , V8, MAF - 14 CUX. Car is running very rich black smoke and huge fuel consumption. When checked the reading from MAF on idle it is 12 to 13v which is very high. it’s supposed to be 1.3 to 1.5v. Appreciate any leads what need to be checked next…...

Will try that out and update you here. Thank you 🙏

Great… thanks. I had black smoke and engine not producing enough power is it becoz of this ?

Car : Discovery 1 3.9L V8i What happened if the fuel pressure regulator vacuum hose is removed? I noticed FPR vacc hose is missing.

Hi, I'm facing a new water leaking problem on my disco 95 its on 200k, Km. i have notice that if the car is parked for days the coolant level is good, when the engine is on start or running the coolant starts dripping under the car away from the radiator. The first time i notice was when I’m...
