Engine just died

[spitzie]

Hi,

After a duty visit home in other car and forgotting to connect the battery charger, got in my Tam this morning and it started. Drove to work to short way, as I was late, so the engine really didn't get very warm (oil temp reach 30). Coming home, it started first time, drove about 1/2 mile to road junction, press the gas a little to pull out and the engine just cuts out. Tried restarted and it will not fire, turns over fine but just will not catch.

Got the AA out, and his laptop expert was not help, but he checked the injector and fuel pump both fine and there is 1/2 tank of V power. He thought they wasn't any pressure in the fuel line, but neither of us knew which end of the injector rail if the input and which the return. Eventually flatten the battery and had to be relayed home, and is on the charger. It only had a full service 9 weeks ago.

Anybody got any ideas what may have caused this?

I had a very similar thing recently in my Tuscan. Started it up and ran it for a short time. No problems. Then went to start it the next day and nothing. As I was getting some work done I left it but I wanted to sort the air box out so took it to bits and the air filter was covered in oil from the breather pipe. The car started after a few turns without the air box on. Put a new air filter on and no probs since.

Might be worth a look.

Thanks I'll check that out

Check the connectors on the wires to the coil!

The AA guy could'nt work this out.... I would guess he is one that relies almost totally on his magic all knowing laptop (I understand the wizard of Oz supplies these). I guess he obviously did not take off the airbox and investigate. The supply to the fuel rail is at the rear of the engine and the return is off throttle bodies 1 and 6 (the throttle bodies are group linked 1-3 and 4-6). the returns' off 1 and 6 are connected to a common single line that is all Tee pieced between TB's 3 and 4 this then runs back to the tank. There is a pressure reg at the front of the fuel rail which bleeds fuel off to the return. Just underneath this reg is the return line from throttle body 1. He could have pulled this off and connected a drain tube to check the return flow. On tick over the return flow is fairly high, backing off as the engine draws a vacuum.

Good luck

Sounds exactly the same as mine did just a few days ago.....Exactly.

Check the Ignition Coils Fuse. (On a Tuscan it's fuse number 17).

It's back from the garage. The problem was due to the multiplug on the water sensor (The one next the coil pack, I was told) becoming very badly coroded. Ths meant that too much fuel was being pumped into the cylinders, flooding them, hence the problem starting.
