Default B230 no start problems

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

How long was it running "fine" before it started "flooding itself"?

Have you done any tests such as the ones in my sig?

Asking why your car doesn't start with no diag info is useless.

Hearing them doesn't indicate it's getting to the correct pressure.

But always check for spark first. Follow ZVOLV's guide then get back with more info.

Sounds like it really could be flooding. The fact that it runs on ether means it's likely a fueling issue.

You can pull the rail and reground the ground wires and then power the fuel pumps or crank, with the injectors unplugged for safety AND ignition disabled, and see if they leak.
