Ok, so my 89 240 sedan will not start. Last week the fuel pump went out then the relay would not click after check relay to make sure it wasn't that I read somewhere on here that the ecu ground might be bad so as a temporary fix I put the ground on a toggle switch. It ran fine but now the car won't start and is flooding itself. Pulled the plugs covered in gas with the fuel cut off the engine will stumble to start but obviously won't cause there's no fuel but the minute you turn fuel on it floods. I have replaced the coolant temp sensor and have a new air mass meter on the way. What else could it be that is making it do this? Thanks guys Ben
