Left key on overnight. Two fuel pumps pumped tank dry, charged battery, replied relay under seat, replaced ignition lock cylinder and keys, replaced outer fuel pump, fixed fuse able link (pink with black one at solenoid). Now no start as pumps do not work.
Spray stRt fluid all is well.
Jumped power (twelve ) direct to pumps and they work but no fire up.

OK how did you jump power to the pumps, Through the relay or did you jump them directly?
If the pumps stayed on with the key in the on position the ECU/EEC module is faulty. It has a time out function that is supposed to shut off the pumps if the key is on but not turned to start after about a minute. It also turns the pumps on when you turn the key.

As much as I hate to admit it two and a half days later of horrible horrible times under that car and bloody fingers and everything else that goes along with it I don't like to say it but it could happen to you as well as it happened to me I forgot to put gas in it and as soon as I put the gas in guess what happened it started up and I'm on my way

I would check the pump timer anyway. It should turn off the pump if the key is left on.

But it wouldn't be the first time that the repair was "added fuel to customers car".
