Go to www.clarks-garage.com.  Your problem is probably the fuel pump
relay.  Also, recommend you clean the battery to frame and engine to
frame ground connections.

You can by pass the relay to check.  Clark shows you how.
Wiring diagram in Haynes Manual at most Barnes and Noble or Amazon.

Bill Noble has posted the links for the complete manuals at least 50 times in this group. (Yes, including "Electrical". Do a search of the group. Good luck.

Another thing,  make sure it doesn't have a factory alarm and immobilizer.
If it does and it is faulty, it will act like a faulty fuel pump. I had this
issue, drove me nutz. Clarkes garage shows how to bypass the alarm.  Best of
luck!
