Thread: 94 D1 V8 dont go

Removed the rotor? .... Have you checked the "C" clip is OK in the dizzy .....

Are you sure the rotor itself is OK? .... Also, Inside the dizzy cap ... Check the carbon button in the middle is not missing

Thanks mike 90 RR , yeah really didnt look at the dizzy cap for too long
C clip is fine
Still im not getting anything out of the coil lead , as if is not triggereing . So with the coil lead pulled at the cap end and held near earth , still no spark ., but if i tap the negative terminal on the coil to earth , i can get a spark out of the coil lead . wish there was some way of measuring the pulses

I left you a PM.

Basically, just hook up a multi meter to the pick up wires. You will get a resistance reading that should be steady as you wriggle the connectors. When you spin up the dissy the voltage generated by the pickup will cause the meter output to jump about, depending on how fast you spin it. Slow spin will see a jump at each cylinder tooth. You should also be able to read AC voltages as you spin the dissy. I just tried a spare dissy and it reads 3300 ohms steady and up to 3V AC when spun.

Also check at the dissy proper as the pickup cable might have died. Any old twin flex will get it going, just route it away from the alternator and power leads.

Hi 400HPON Gas,

The engine cranks over fine but doesn't start.
Does the Disco have the factory fitted electronic immobilizer.
'
If it does it could possible be the "Spyder" box (deep inside the dash)

My 1996 V8i one day just wouldn't start, cranked over fine but nothing....checked distributor, coil, leads, changed the flat electronic thing at front near radiator and it turned out to be the immobilizer.
This spyder box is an Black rectangular box with a circiut board inside and a common fault is for a small section on the circuit board to burn out and wont let the vehicle start.

They are expensive to buy new but over here in Perth a couple of the landrover afternarket sellers have a replacement unit they have rewired to bypass the broken circuit.

Unfortunately you have to pull half the dash out to get to it as its located behind the radio near the firewall.


Baggy

Thanks Baggy , thats one to check out as well . But as there is a constant 12V at the coil positive ,even when cranking , then the immobiliser , whatever it does , doesnt cut the ignition feed to the coil , well not on this 3.9 B series anyway .
It appears that the magnetic coil pickup is faulty , a $300 part . In the meantime Ill get a complete dizzy,amp ,Coil from Beeutey for a decent price .
Just wondering how this immobilizer works , does it cut ignition feed to the coil ? or perhaps does it ground out the Negative side ,so it doesnt pulse ? MMM interesting !!!

$300 for the pickup, your getting robbed, Last one I got was about $140 from memory. Amps are about $65.

yep , Rovacraft wanted $278 plus GST for the pickup only , wouldnt touch any LUCAS amp , theres a million Bosch 024's around for nix.
