'02 WJ, Fuel Pressure Bleeddown - Replace Pump or Pump Seal???

[alexzrodriguez]

Hope someone can help out with this. TSB 1400201 recommends a ful pump module seal replacement to fix long crank time problem. Dealer has checked and verified the line pressure bleeds down fairly quickly. TSB applies to 99-01 models only. Questions : Does anyone know why this TSB wouldn't apply to 2002? Is pump replacement the only solution? (BTW - Crank Pos'n Sensor already replaced). THANKS! -Alex

It might. After the TSB is issued, the problem, in this case the pump seal, is supposed to be fixed in production.

Is pump replacement the only solution?

You can just replace the seal, but the dealers usually replace the entire pump ass. since the labor is the same.
But it may not even be "the" solution since long crank times may be caused by other things, but since the pressure bleed down was verified, its a probability, along with a leaking fuel injector, fuel pump, fuel regulator...
It's hard to isolate. I would ask the dealer to guarantee that it fixes the problem first. (good luck)
If it is the pump, you may be in luck - look at your warranty, depending on the year , it (the fuel pump) may still be covered.
Fuel pumps for the 2000 year model were covered for 7 years.
