WJ 4.7 V8 starting issues.... 2001
« on: June 04, 2011, 11:44:50 AM »
Hi,

Got a WJ V8 turns over for a long time before starting, then it will be fine another time starting within a couple of seconds... idles, revs and drive perfectly

Any ideas? Thanks in advance Maf

It's the residual fuel rail pressure leaking back through the fuel pump. If you switch on, pause, switch off, then crank, it'll fire up straight away. Cure? Fuel tank out, either fit a repair kit to the pump or replace it.
