poor starting

[m1ck]

good evening everyone

as a newbie i have purchased a 1998 xj8 sport 

when i start her i have to keep pumping the throttle pedal otherwise she wont start

would any one have any suggestions what it could be please

many thanks in advance

Duff Plugs or maybe a clogged fuel filter etc?

plugs are about £70 a set so brace yourself!

I cant understand why that would be the problem though because when she starts she runs fine?

[srad34]

Building up fuel pressure to start the car. Did you get it sorted?

[m1ck]

No not yet but i have noticed when im starting her im not pumping the pedal now i just let her start on her own

regardless if she is hot or cold thiscould be instant or take at least 30 seconds

Just a quick update i plugged an OBD reader in and the fault code tells me the crankshaft sensor
