Ok, I bought a couple disco 2's a few weeks ago. Neither of them are perfect. The 2000 needs head gaskets, which is no big deal. However the 01 is being a real pita. I will keep to the basics for the sake of time. The guy I got them from said the M&s lights are on because of an xyz switch and that it should run when replaced(seemed odd that the trans wouldn't let it start, but I said ok and went home with it) he gave me a switch he said was good, and I replaced it. I realigned using the neutral and neutral positions then cranked down the bolt. Then the battery was junk, replaced with new, trickle charged to full. Good battery.
It will crank for days, no spark, no fuel. So I look it up. Decided crank sensor was next. Just happened to find one in the glove box... Suspicious. So I crawl underneath and find another one put in, with shims first. So I put the glove box one in, same thing
So I put the one that was in back in correctly, same thing.
So I buy a new one, seeing as all the rover forums put the no spark no fuel into the cps category I figure there has to be some truth to it. Plus $60 is worth a shot.
New one in, same thing.
I figure it to be odd that the coils and fuel pump go out at the same time, so I jump the fuel pump relay, I can hear the pump running, but only when I jump the relay. So I think the wires on the back of the motor for the cps have been rubbed through, good continuity all the way to the ecu plug.
So I start with security stuff... Key fob works fine, unlocks locks..... Tried the generic 1515 eka or whatever code, never acts like it letting me put it in.
Inertia switch is good, even jumped it to make sure.
I'm at a loss
The coils could be bad, however I'll chase that when I get the key to turn the fuel pump on to make sure it's not related.
Service engine light does not come on
Scanned for codes, none beside the airbag system that's been gone a long time.
2001, disco 2 102k miles
Thanks in advance for any insight
Now thinking next either ecu is bad, or they may have put in a new ecu that isn't compatible? But then would it crank?

 

Hi, my name is zach.
I now have 2 rovers.. 2 disco 2's and a 2002 rangie in the rhino trim. I love the Range Rover, got the 2 discos to fix and sell one and end up with a no out of pocket one. Need something I'm a little less scared of beating up the paint on the trails.

Ps, dash shows the M&s, srs, temp light, oil pressure, battery and little rover rolling down hill with an exclamation lights after start attempt

 

i "believe" the order on the crank sensor on a DII is:
sensor, spacers then nuts, it you have done it the other way the sensor is probably to far out for the flywheel to pick up the pulse. but i could be wrong

 

That is correct, and that is how I have it. Found it the other way. Then fixed it

 

Have you checked the fuses, both underhood and under the dash?

 

Yes, 3 times over... And put the relays from the 2000 that runs in it. All the relays from the 2001 with the problems still let the 2000 start and run. 2001 has same problem with other good relays

 

So, found the problem!
Now how do I replace the ecu? Any tricks?http://youtu.be/k0YcC3j2C5Y
