nway my question is..
since the computer isnt sending the 12V signal to the relay to close the circuit can i manualy do it? by running a wire straigt from the battery to the relay with a switch ?

I would think if you straight wired it, you risk having the fuel pump on all the time. Unless you are going to hook it to a toggle switch, but I'm no electrical guy so I may be wrong.

Not

I would say no as when the fuel pumps are not shutting off you can not start your engine.
The reason for this is while the fuel pumps are running the fuel injectors are not firing.

The real source of the problem is that one or more electronic capacitors have gone bad in the computer. If the capacitors were replaced then the computer would run for another 17 years. Unless you let the smoke out of the computer this is about the only thing that goes wrong with them.
Electronic capacitors can sometimes heal themselves for short periods with the power on and work for a little while but they will give up totally sooner or later.

If you are good working at board level you can replace them.

Here is the URL:
http://www.3si.org/wiki/index.php/How_to_Replace_the_Capacitors_in_a_1G_ECU%3F

The URL is for fixing a non-Ford computer but the information is close enough and you just have to change the values of the caps to match yours.

I just saw that my spell checker let me down in the above post.
I said Electronic capacitors and should have said Electrolytic capacitors both times.

Most of the time poster are not able to work at board level so we just say replace the Computer.
