HELLO BLUEPONY!!! CAN YOU TURN THE ENGINE BY HAND??? YOU ARE WASTING EFFORT UNTIL YOU ESTABLISH THAT THERE IS NO INTERNAL FAILURE!!! AS HH SAID WITH NO PLUGS AND TIGHT BELTS YOU WILL BE ABLE TO ROTATE THE ENGINE!! SORRY about the capitals but its seems you still have not made this vital, easy test. You should be able to see the ring gear teeth with a torch and mirror as well as the motor is turned.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?
