non starting 3.9
« on: October 14, 2007, 17:27:25 »
Last night my 1999(series1)discovery cut out and wouldnt restart.It has LPG conversion and was running fine and without warning just died  .i have since found out there dosnt seem to be a spark and also after loads of cranking there is no smell of fuel(petrol or gas)  even though the fuel pump primes when the ignition is switched on :-k .
It has recently had a new distributor fitted(less than 100 miles) with a new link lead to the amplifier/coil.First port of call was the alarm spider.Pulled it out and soldered the link leads on like in bogmonsters thread but still no joy  
So what i was wondering is -
1-how the ECU gets its signal to energise each of the fuel injectors(distributor or crank sensor)
2-How to test the distributor/amplifier
3-could the lack of spark/fuel both be linked to the distributor
4-am i looking in the wrong place  

Help please,i havent got much hair to start with,but what i have got is being pulled out in lumps :oops:

Ta very much
Paul

Well need to wait till the grey matter wakes up to answer the first 3 but have you checked all the spade connectors are still attached to the fuel valves.  The system fitted to my carbed v8 also had an extra wire going to the coil which when removed would stop it from fueling petrol or gas.

Cheers Peter,found out today that the ecu gets an earth pulse from the coil to trigger the fuel injectors.According to RAVE if i connect a voltmeter bewtween battery(+) and coil(-) the reading should be 0v with the ignition on or off and increase in voltage when cranking but i have got 12v with ignition off,0.3v with the ignition on and 0.3v with the engine cranking :-k
I REALLY hate car electrics ](*,)
Got a alarm spider bypass lead coming tommorow so will do some more in depth testing if that dunt cure it :roll:

Just noticed your local, I have a suspicion you're very local in fact.

D'oh, thought we'd spoken before.

Probably about time I offered to pop round.
