plugs cleaned and back in, good as new. all plugs sparking fine. coil obv ok. new rotor arm. fuel on plugs and can hear fuel pump go when ignition is turned on. new ht leads on yesterday. timing belt ok. air flow meter discon and tried, no change. the recon no change. HOWEVER, I cant find the fuel cut out button, but would fuel pump go if it had cut out??
Cheers
Rossko:
I think the fuel cutout is on the engine side of bulkhead, passenger side. But no,pump would not run if it had tripped.
Check voltage at coil +ve when cranking, you want more than 9V. Less than that suspect immobilliser spider or body earth straps

Hi,
Any luck yet?
where are you in essex ?
If you need someone else to help stare under your bonnet give me a shout, im off with the kids this week (half term) Mine is a 97 V8, happy to pop over if its not to far
Andy
PS
on mine the fuel cut off button is behind the washer bottle on the bulkhead, but, as Rosko said the pump wouldnt run if it was off.
Thrasher:
I hope you timing belt isn't "ok" .... 'cos the 3.9 has a timing chain ;-)
Check coil - mark sure you are getting a good fat spark, not a weak one.
This one is worse, your alarm spider has died. You can bypass it by jury rigging up the coil to the battery......
LANDYTIM:
Had a mechanic friend look at it yesterday and he said it may just be flooded. Did as he said and she fired but the battery is now dead from keep turning it over! Is it likely that it is this?
