Hi, I have a problem with my 2004 Santa Fe, 2l diesel. Will try to keep this short!
When driving it suddently 'heaves' (not sure how else to describe it), then it cuts out. I wait about a minute and then it restarts.
At first there was no 'heave' but there would be a momentry loss of power (I thought it was the clutch). Then it progressed to the 'heave' and then cut out, this happened now and then. Very quickly it started to do it everytime I drove it. My neighbour mechanic blew down the fuel line, said the fuel pump in tank sounded ok, seemed to do it more when below quarter of tank.
So I kept tank topped up, it seemed ok, then on one 11 mile journey it did it 3 times, the last time the engine management light came on, crawled it home, after which it would not start at all. The computer said it was either fuel rail or coolant sensor. Neighbour replaced coolant sensor, it started ok. Tried it next day - 6 miles and it heaved and cut out again. This time no light coming on.
I'm due to take it to another mechanic this weekend, but wonder if anyone can point me in the right direction to the fault. I've read about cam sensor, crank shaft sensor, fuel pump at back of engine - but just wondered if anyone has had the same problem and knows how to cure it and what kind of costs it incurs.
Thanks.
