Hi,let's see if we can work together to get to the root of your problem! will try my best to help!

Two things to check, is the fule transfer pump suppying the injection pup with fuel? Seconds is the fuel solenoid on the front of the injection pump, is it getting voltage and allowing the fuel passage to open? See links above

I see question is still open, did you see my response? Please rate to close the question.

It is getting voltage do not know how much it should be receiving. It will start without the selonoid and then won't when it is put back on

Solenoid has to have full battery voltage, with key on at all times, to stay open.

if it's not? Only receiving 9 v when I test

Battery voltage above 12 volts? Follow the solenoid harness back, using wire colors and look for bad connection or relay that is not sending full voltage to the fuel solenoid.

Fuses inside can and on top or engine are good

Do yu have 12 volts at the fuses and to the relay that holds the fuel solenoid in the retracted position? Where is the voltage being lost? Did you try to trace the wire back.

Customer: replied 4 months ago.
7.5 volts at selonoid
Customer: replied 4 months ago.
Tracing but it's tough

Yes, try to use the wire color for tracing back to the relay/dash area.

Customer: replied 4 months ago.
Wires loose under floormat and from Connectors

I assume that was problem? Good Job!
