wiggled some lines on fuel tank and got the truck started barely made it to the garage no power and missing.Leak in fuel line? they just replaced the sending unit. Can I get codes without a code reader?

 

CPS?

 

Note to self never let truck get below 1/4 tank :doh::doh::cursin:. It got air in the line. cycle key 5 times then drain valve while cycling don work. To properly bleed fuel system.....:fyi:

if you have access to an air line tightly wrap a shop rag around a blow tube and stuff it into the fuel filler. Have someone release the bleeder vale on the injector rail while pressurizing the fuel tank. This will force fuel into the line at low pressure [The rag will loose some but not all the pleasure applied] and bleed the air out of the line. When fuel [with no sputtering] is flowing out of the bleeder tighten it down and you should be good to go.

 

... Or just cycle the key a few times and be done...

 

I cycled the keylike 20 times do you know why itdidnt work?

 

I would guess your pick up could be plugged or your fuel pump is getting weak.
