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.

98 landrover discovery will not start. It just spins


does it have fuel pressure? to find this out get a can of spray starter fluid from a auto parts store, spray it into the engine air intake, if the engine starts you most likely need to replace the fuel pump which is located in the fuel tank.

1996 discovery starting problem


Hi.

Make sure there is voltage going to the fuel solenoid on the pump, i did the same with my landrover and it just would not start or would start and just cut out, turned out to be the wire going to the fuel solenoid was not working, just re-wired from a wire behind the dash board that supplied enough voltage, that when the landrover had started the wire then supplying voltage.

Just check by putting a multimeter on the fuel solenoid wire and turn the engine over if the voltage drops to below 12v then it`s most likely the same problem i had.
