HAVE A BIT OF A QUANDRIE ON MY HANDS, AFTER STARTING UP THE RIG IT HAS GOOD POWER UNTIL IT REVS PAST ABOUT 1500 THEN I HAVE NO POWER. TURN THE TRUCK OFF AND ALL IS GOOD TILL I GET THE ***** PAST A CERTAIN POINT AND DIES, NO POWER. CHANGED THE FUEL FILTER, CHECKED THE CODES AND NO CODES LEANING TOWARDS FAULTY LIFT PUMP{0122,0500,1596,1693} COME ON BOYS HELP THIS HILL BILLY IF YA COULD!!!!!!!!!>>>nomad

 

- your public profile indicates that you are driving an '02, could you fill in your signature so everyone can see what you have - include all the relevant info - tranny, gearing, mods - this may make it easier to help you troubleshoot the issue....

 

are all those codes being thrown ?

if so i would say lift/inj pump

i had similar power loss when my boost sensor went out (no boost)
