Hi all,

Got a fuel problem last night. Had just used the Coop and parked it for 20 mins. Got back in and it started and then spluttered to a halt as it just wasn't getting any fuel. Tried a few more times with same result and then finally not even a splutter Had to get it rescued and leave it at garage last night.
Car Cranks over fine with no warning lights, just not starting.
Where do I start my fault finding
?

When you say "had just used the Coop" was that a short journey? If so, then the engine might have been flooded (with fuel) making the restart after a short time difficult. To get a flooded engine started, I floor the accelerator pedal before switching on the ignition, then keep the pedal pressed down while cranking the engine. This allows as much air in as possible and eventually it should cough and splutter back into life. However, don't spin the started for too long at a time, and you may even flatten the battery in your attempts to restart (which may set off the alarm) in which case you might need to "jump" it with another battery, or just give it a quick charge before trying again. If you are pretty sure that nothing has broken in the meantime, this should work, but non-starting can be caused by many other problems...

Can you hear fuel pump priming for a few seconds when you turn on ignition? If not, check yellow connector near fuel cut off switch (and press the fuel cut off switch button to reset it while you're there, just in case!), usually hanging beside fuse box. It can become corroded, or have dodgy connections, usual solution is just to cut it out of the circuit and solder the wires directly together.

If fuel pump is priming, what exactly are the injection light and code light doing? Both should come on, go off and stay off during cranking. If either isn't coming on at all, is staying on or coming back on during cranking then that will point at the source of the problem.

If it's starting OK now that it's cooled down then probably just failing injectors, as they often initially fail just when hot but are OK once they cool down.

Thanks guys, will check your suggestions out when I get her back next week.

Update: Of course the coop started the first time they tried it at garage, so it could be heat related as the engine was still hot/ warm when it first failed, though I did try it once more when we left it at the garage last night and it was cold by then.
I don't think I heard the pump and I do normally notice that. So a good shout there Graham.
