Thread: Help Disco V8 will not start

Dizzy loose and turned retarding the ignition timing?

Sounds like you might have damaged the air flow meeter.
try holding your foot to the floor on the throtal and start it on petrol.
It should kick a bit and then start.
Mine dose the same from time to time.

no movement in the dissy, tried with foot to the floor its close but just wont fire , recharging the battery at the moment

As you had a backfire,just to be sure have a look behind the Plenum chamber and see if any of the hoses blew off. The larger hose that comes from the Throttle body to the rear of the plenum. If off it won't start or run correctly

If your dizzy isn't moving then I would leave it for the weekend and have a few beers.

It's not a good sign.

Ok 3.9 V8 duel fuel has been running perfectly, replaced leads, plugs dist and rotor and coil in the last 3000km.

Parked up last night, change serpentine belt this morning, went to fire it over to check belt.

backfire through air filter and now refuses to start................ turns over wants to start, fuel in rail has spark

what am i missing what should i try next ?

changed serpentine belt this morning might be the problem. check that all is as it should be, no wires knocked off, Bob

well i have all i need for it to fire but it just wont, its close but, spark fuel and air

have left for the day let the battery get to full charge and let the plugs dry out

and will try again in the morning and check it all again.

the dizzy reference was more to it hadn't moved for timing the rotor spins fine.
all hoses are inplace

thanks all for suggestion and points to check will update tommorow

Once batt is charged and you are sure the timing is set correctly (I would take out no1 plug and reset the timing that way for "****s and giggles"), with all leads plugged in and you can hear the fuel pump going with fuel at the rail, try another thing.......lock then unlock the truck by the drivers door, done this a few times to reset the immobiliser...anything is worth a crack
