Pending p1668 and p0563 code non start on landrover shuts down while idling/driving sometimes no spark and fuel

You might need a workshop manual for that one or someone who has one anyway

year and engine?

Check for ignition spark when it quits could be an ignition coil problem ....when a bad coil gets hot it could fail until cooled off...

put a fuel pressure gauge and see what the start up pressure is it should keep pressure over night with only a couple pounds of pressure drop

i need to brush up on landrovers

what year is yours
SU carbys or EFI system

spark plugs means fuel ....not a diesel
leads and coil and electronic distributor fitted

a bang when started ? that a backfire through the air filter ?
timing out or fuel issue

you say running rich running rough
the 02 sensors may need replacing
clean maf and air filter
timing chain or belt slipped ?

starting if a separate problem
starter relay or starter and solenoid to be checked out

Need to know,is the starter turning the engine over?Is it getting fuel to the fuel rail?Is it getting spark?

Hi,

Can you confirm what brand the stereo is? If it is the Visteon brand that Landrover fit then I can help. Just let me know.

Thanks.

I have a series 2 v8, its cutting out when driving, when idling, have checked for spark..it didn't have any then when I came back after half an hour it started, the other time I disconnected the battery for half an hour or so & it started...nay suggesttions...??

not likely a fuel issue,
try running it in the dark of night , no lighting and look for sparks ,
have the ignition coil tested , be sure it has good ground.
pull each plug and watch the spark ,does it maintain the blue long arc.
tune a am/fm radio to the sparks ignition sound an listen to it
a portable walkman can lead you to the faulty spark,
or just have them monitor the spark at the shop.
