Hot Start problem on DGS here we go :(

[Dan6457]

As eurotec is drawing near, the delorean has decided to be naughty. Today the delorean wouldn't start when hot. It did eventualy after a lot of cranking and then spluttered into life running on a couple of cylinders until it sprang back into life properly. It did this twice when I had left it for a short while (30 mins ish), but as a test I turned it off and back on again about 5 secs later and it fired up perfectly. Am I right in thinking these are accumulator symptoms? ie loosing pressure when left for a while.

If so, can they be repaired or is it a case of ordering one up from Ed or something?

Sounds like accumulator.

Just replace.

NickT

ps I can do a fuel pressure test for you at eurotech to confirm this or not, in exchange for beer

[Dan6457]

Sweet sounds like a plan Want to be sure before I shell out 80 quid

I'll bring my volvo venturi with me too as I STILL havn't had chance to fit it so there might be time to do it at the event. Could you bring your CO tester too? In exchange for another beer?

[NickT]

Ok I'll bring the gastester too.

cheers mate Tyson

Hi Tyson,

Its a bloody pain isn't it. I thought it wasn't going to start this afternoon, then it finally coughed into life but it was running on 2 cylinders or something for a few seconds, it was shaking about and sounding horrible then a bit of a rev and it was fine again. Worrying moment

could it be related to the fuel injectors too??

......especially on Chips !

I will bring my engine tuning gear. It is a Technical / Beer session after all !

btw Try pressing on the metering flap the following morning after running the engine. If there is no resistance at all and you can bounce this flap then the accumulator is duff or you have lost system pressure back through an o ring or check (one way) valve.

I have the Bosch tool for checking fuel pressure/ spray pattern of fuel injectors but I don't have any copper washers to replace them.
My fingers are also like a bunch of bananas so if you want to remove them yourself I can test them (for beer??? )

I have a bag full of fuel injector copper washers ... i will bring these with me to euroTec

I doubt its injectors becuase when its running it purrs perfectly. When I get home from work I'll push the flap down and see. That will be about 24 hours since it was ran last, is that too long or should there still be resistance?

Ideally there should be a resistance showing that there is still pressure in the fuel line.

One thing to note, when you do press the flap down and the system is pressurised, this will inject fuel into the cylinders so only do this as a check.

Rough test, after starting the engine, stop it and do the test again.
If there is definately no resistance then chances are it is the accumulator.
