Hi, i am having a major problem with my 1996 4.6 litre gems engine. I was going to work a few weeks ago and had to slow down as i slowed down the Engine stalled (it's a auto) and will not restart. I have changed the plugs changed the fuel filter and the fuel pump, the coil packs and the crankshaft position sensor. I am now at a loss as to what else to try when i try to start it, it tries to start but just wont fire any cylinders. Any pointers would be very helpful and thanks in advance alex
