Stang wont start

[ruger77]

I forgot to shut off my sirrius radio in the car 2 days ago and it killed the battery. Chargerd the battery, now the car wont start. I got spark, starter is engaging but no fuel. I checked emergecy fuel shut off, OK. I pulled the fuel relay and jumpered the connection, fuel pump energized. Went and got new relay still wont start. Any help?????????? Its a 88 5.0 GT.

so the pump works? Is there fuel at the rails? Try an easy part like the filter first and work your way up to the injectors.

Maybe the ignition switch went bad? I had a neutral safety go bad while my car was down a few days. The fuel pump kicks when its jumpered, but nothing when the key is on the "run" position. I believe its also cut off when the key is in the "start" position. Could try jumpering the hot lead from the ignition switch directly to the relay feed. I believe its the large diameter yellow wire coming out of the ignition harness.

I will give it a try. Thanks

I started a thread in another forum for a similar problem. I pulled the interior out to put new floors in my 86 GT and after reinstalling, I can't get the fuel pump to work. I'm new to the Fox thing. All this electronics, relays and EFI stuff is a little different than the good ole carbureted stuff.

Couldnt get it fixed so it went to the garage and the relay for the ECU was bad. $14 part!
