I have a 2002 kia sedona 2.9 diesel 62,000 miles.two weeks ago a piston blew up,the car was out of warranty in nov.2005. An independant garage is carriying out the repair. the piston,piston rings and the timing belt have been replaced(at an astonishing cost for parts),but the car will not start at all,it does want to start if diesel is poured down the manifold.The car was running prior to the piston and timing belt replacement The Kia dealer is of no help at all , they said it could be the fuel pump. Can anyone help with advice on what the problem is or if anyone has heard of this happening before,i am desperate as no -one seems to know how to fix this vechicle.In anticipation,Mike Healy
I'm not familiar with the Kia 2.9L diesel specifically (it is not offered here in the U.S.), but I do have some general experience with GM and Ford/International diesels, and the basic principles are the same for all.
If you can get it to run by pouring fuel down the intake manifold then it is most likely a fuel related issue. Fuel injection is to a diesel what both the fuel supply and ignition system combined are to a gas motor.
Beginning from the start, you could have no fuel in the tank, a clogged intake in the fuel tank, a clogged filter, a bent, crimped or disconnected fuel line, a bad fuel transfer/lift pump, the fuel injection pump could be damaged, have an electrical connection disconnected or be severely out of timing, disconnected, clogged or crimped fuel lines to the injectors, air in the fuel lines requiring the motor to be primed, faulty or clogged fuel injectors, or perhaps a bad connection or bad ground on any of the electrical components for the fuel supply system. This is not even taking into account any of the possible electronic issues you could have with the on-board computer/ECM that could be preventing your motor from running. Check all of your fuses, and ask if there's an automatic fuel shut-off somewhere that needs to be reset. Change the fuel filter, drain the fuel/water seperator, purge the air out of the fuel injection lines and try again.
You're only choices are at this time is to relieve the independent garage of the job and either send it to the Kia dealer or a shop that specializes in diesel motors and have someone who has extensive diesel experience work out the problems. Working on a diesel is NOT like working on a gasoline motor without spark plugs, regardless of what anyone may tell you.
Good luck, I think you're going to need it - Jonathan
