Any one else had lift pump problems ? My truck has only 11,000 miles & started surging real bad the other day. Carried it in & they ordered new lift pump....They called me today & said the New lift pump started surging Real Bad when they took it for a test driven. Mechanic had to use both feet on the break to get the truck stopped ......so they ordered another one that should be in Monday. Anybody else had any lift pump issues ?
