S2A109RAG Posted January 20, 2014 Share Posted January 20, 2014 Well after a battle getting to the start stage of this Megasquirt install I turned the key today..... It just burst into life.... just amazing... sounds so different to the old setup... PROBLEM,,,,,,,,,,,,,,,,,,,,,,,!!!!!!!!!!!!!!!!!!!!! I turned it off...... And for the life of me the nasty thing will not start............... Any ideas????? I have touched nothing. so it started. it ran for 20min.... no hastles. turned it off. Tried to start it again straight away.... no good.!!!! Is this a common fault? do I have enough earths? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 20, 2014 Share Posted January 20, 2014 Disconnect battery, I had this at one point, basically the ECU was being kept alive by a wiring fault, I forget what it was though! Then try again, see what happens, and fingers crossed. Also check a plug or two, see that they are not flooded/choked up badly. Quote Link to comment Share on other sites More sharing options...
S2A109RAG Posted January 20, 2014 Author Share Posted January 20, 2014 Well, it seems you are on the right track. After removing the plugs..... all 8. and replacing them with another set(not new) it fired up first turn. the 8 i removed are soaked in fuel. Is there a solution for this issue of flooding? of course it will not start again after running for a time. not that im complaining... it runs!!! it idles at 2200rpm ( nicely ) no hesitation revving at all. no Air leaks..... that I can see. I also have no reading on megatune for water temp.... but it comes up fine on the gauge. although I do need to sort the radiator........ it is blocked up...

Hybrid_From_Hell Posted January 20, 2014 Share Posted January 20, 2014 AH !Guage in car is mechanical guage on engine Guage on MS Megatune if showing -40 means Water CTS SEnsor is not working either wiring fault of more likely sensor fault : From me website : CTS (Coolant Temperature Sender) SensorGenuine Branded 'FAE' CTS - 'Coolant Temperature Sensor' - with correct codes for Megasquirt ECUs. If you suddenly find your engine is running very rich, starts fine but as it warms up gets worse then open 'Megatune', look at the Coolant Guage. If it reads -40 then this sensor has failed. DO NOT Buy an Intermotor unit - you'll be replacing it very soon again, FAE are the highest quality, and this unit is useful to carry as a spare - Hot CTS Sensors do not like ice cold water long term - even FAE ones Its massively flooding the engine cos it thinks its a cold day in siberia !

S2A109RAG Posted January 21, 2014 Author Share Posted January 21, 2014 Although as Nige has mentioned its running rich as hell..... It runs better than it ever did...........................!!! Quote Link to comment Share on other sites More sharing options...
S2A109RAG Posted January 21, 2014 Author Share Posted January 21, 2014 Fail!!!!!!!!!!!!!!!!! The temp sensor plug had not had the pins seated correctly....... click... and their in...... starts first time every time.... Cheers Nige, Although If you have a suggestion on how to get it to Idle below 2000RPM that would be great Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 21, 2014 Share Posted January 21, 2014 Doesn't look like you have blocked off the ISV yet, it is probably fixed open hence the high idle. Clamp or stop up the hose to it if you aren't using it yet, then set idle with the idle screw on the plenum. Quote Link to comment Share on other sites More sharing options...
S2A109RAG Posted January 22, 2014 Author Share Posted January 22, 2014 Spot on, Thanks for your help and eagle eye on that one...... It now runs like it should.... Quote Link to comment Share on other sites More sharing options...
