Question wiring problem

I have a 1986 ford f-150 truck 302 motor with fuel injection that used to start up and shut off, then i played around with the wiring and now it won't start atall. I got spark and injectors and the fuel pump is not kicking in anymore. If any body knows what my problem could be please let me know I am at my wits end, i don't know what eles to do.

I'm not sure what you just said, cause you kinda ran your sentences together, but if I understand you, you have spark, but your fuel pump isn't working. If that's the case, you want to get a test light or multimeter, and test your voltage going into your fuel pump. Check a manual to find out what voltage should be there, if it's there, then your pump is bad, if not, then you probably either disconnected or shorted out something further back. If you don't have a multimeter, you can for testing purposes run a wire from your battery to your fuel pump hot lead directly, and see if it turns on. If it does, you have a problem further back in your wiring.

You may want to check out the relay that operates the pumps.
If not the relay, check the wiring and connector at the relay.
All of this I believe is under the hood on the passenger side.
