griggan, no I don't have it running yet.....well it runs but not well. I have taken a break from it to keep myself from pulling my hair out. I will look for what you described and see if it helps my issue. Thank you for you help.

 

Finally got my boneyard engine overhauled to replace the engine that broke the connecting rod and took out the cam and block, ready to start. Alas, I could not get it started, no spark. Stayed up until 4:30 trying to search threads to find out why. Went back today and found some worn insulation on crank sensor pigtail. Ah ha, I have harness to rob pigtail from boneyard engine, too bad it's just as bad. Repaired wiring and tried again, still no spark. Checked relays in inner fender, ok. Pulled ECM and found good size hole in case and white powder coming out of hole like a salt shaker. Think I found my problem!

 

I think you found it too, good job! When you grab another ECU grab the alarm from the same vehicle, it's insurance against more problems if they're not matched. Shouldn't cost much more. Good luck, hope it fires up this time..........it should.

 

I cleaned the ground, and no change. I even unplugged it and cleaned the plug. What is the sensor on the fuel pump called. I was going to go ahead and order one and start there.

 

I think it is the fuel temp. sensor.

 

I checked fire again today, and I don't get fire on 1 & 6, and all the others show to cut out under throttle while watching the timing light. I can see a 1 to 2 second delay in firing on each plug. I can't find anyone that has a fuel pressure gage that will fit a land rover, but I checked with a tire gage and it showed 35psi, but I couldn't tell if it fluxuates under throttle. Looks like I still have a firing issue. This thing is a bugger!!

 

We'll I installed another ECM and finally got it started for a minute or so, until it died again. Now I get the red led light flashing when locking/unlocking doors with key (no remote was given when I bought the truck). Had a couple codes in ECM, but now the CEL does not light when key is turned on as self check. Can the inexpensive scanner pair the alarm and ECM?

 

No, only Testbook 4 can pair the two and maybe Autologic. Any chance you can snag the alarm unit that was paired to the ECU you picked up? The fact that the drivers door lock is enabling/disabling the alarm is not a bad sign but the CEL not coming on is. That's a key factor. What year Disco?

 

It's a 98. Been having problems with trying to get my laptop to fire up so I can get into my manuals.

 

I checked fire and still cutting in and out. It is like it looses signal for a few seconds under throttle. Can someone respond??????????????? I hate landrover!
