1993 Toyota 4Runner fuel problem

Frist of all you need to make sure you are getting power to the fuel pump and if your old one is working then you need to make sure it is pumping this can be dangerous so use a light base oil like a cooking oil not cold but warm insert bottom of pump into oil and hook up connection for a very short period if it pumps any fluid out its not the feul pump or the relay. If you do a pressure check on the feul rail or at the fuel filter this could save extra steps if fuel is getting through then it could be the cadlyic converter if it started losing power over a short period of time then died.
