Tundra will turn over but won’t start once a week !!

New member here from south alabama. I need some help please. It’s my only way of transportation. I’ve got a 2010 tundra, 4.6 v8 sr5. Last week I got out of work and my truck wouldn’t start. I turned the key over and the truck would just crank and crank but never start. I waited about 20 minutes and tried to start it again and it crunk and I drove home. I immediately thought it was the fuel pump. I bought and replaced a fuel pump and the truck ran good for a week and now it doing the same thing again. Can someone please throw any possible solutions my way. I need help !!!!

 

Is it a flex fuel? If so may want to check the ethanol fuel trims.

 

What brand of fuel pump? If anything other than Denso, get rid of it.

 

No it isn’t flex fuel.

 

That fuel pump is fine
Any cel or codes
Maybe fuel pump control module I've herd of bad connections here and also bad mods
Check the obvious fuses, relays, electrical connections

 

.

It’s throwing this code. But this code has been on for awhile. Today I will check relays, connections, and check the module. What is the easiest way to check that module or the relays?
