hi everyone,looking for a bit of advice.ive got a 1999 4.6 p38.engine will turn over but no fuel or spark.this is intermitent and no warnings on dash.sometimes the cental locking activates itself,and when this happens ,it starts fine,ive tried replacing the rf rf reciever with a new updated one but makes no difference,worrying thing is that on way home tonite it cut out whilst on duel carraigeway,luckily didnt cause an accident.anyway it wouldnt restart so called breakdown.waited an hour and heard central locking clickin so thought id try starting again and it fired up just as breakdown truck pulled up,got him to follow me home and cut out again...really dont know where to start,so if anyone can help in anyway id be soooo greatful.....
