fuel pump

Asked by amonk Feb 25, 2011 at 04:13 PM about the 1989 Nissan Pickup

Question type: Maintenance & Repair

My 89 pickup has always had sputtering problems.  Finally this year the engine cut out on me on the freeway.  It acted like it was out of gas.  I had the fuel pump replaced and it was okay for two weeks or so but then it did the same thing again.  I noticed one of the tubes disconnected when I checked under the hood.  Would that be my vacume that is having trouble?

The tube is probably your vacume. you need to put that back where it goes and put a hose clamp on it to keep it on. With out the vacume it will cause the truck to shut down
