Try shutting all doors lock using remote then unlock and try again?

Had an ML 270 Mercedes 4wd a few years ago - a real dog of a thing and it was the most unreliable (and expensive) vehicle I've ever owned. It was plagued with "Bill Gates" problems and I found that by removing and replacing the +ve battery terminal "rebooted" all the onboard computers and got me going again. Had to reset radio each time but it seemed to fix the glitches. Check your handbook first to make sure that by doing this you don't create more problems though.

I had a car a few years ago that had intermittent start problems. I checked all the usual stuff - spark, fuel flow etc but no go. Leave it a while and it would start ok. After a non-start episode I towed it to the agent one time and they found nothing but changed a small in-tank fuel filter and I had no more problems.

When I checked for fuel flow everything looked ok as fuel gushed out of the hose when cranking. Seems that the fuel pump was working ok but the pressure was not quite up to what the computer was looking for so the computer would not switch on the injectors ! There was a fuel pressure transducer some place that I never did find.

it would be probaly a pressure switch connected near or in the tank pick up, might even be on the back of the pumps, near motor, as a suggestion. for example 3 wires into a pump could mean a resistance wire, or measures volyage used by pump for a trigger!

Hi Christopher, Never would have thought of that. I am used to strain gauge type solid state technology but simplicity is good ! Thanks.

Yep - all D2's have this switch. If it has been activated, it will shut off your fuel supply until it has been re-set. Push down on the rubber boot on top of the switch to re-set.

Try disconnecting the battery and then reconnecting. It is a bit like ctrl/alt/delete on the computer. It may reset whatever it is causing the problem.

I did that a couple of times on my TD5 Defender and it worked.

Good luck

if that doesn't work, put a post on aulro website or do a search...sounds like the 'three amigos' problem - there is a reasonably simple and cheap fix for this...
