1990 (G) 300te wont start

[ig_Al_300te]

if this is a '90 car it doesn't have a lambda sensor. shame, because you can set these up without a gas analyser. just tweak the meetering head adjustment screw until the car goes into closed loop (voltage at sensor varying 0.1v to 0.8v or thereabouts) then keep adjusting till the voltage at the EHA is in the region +30mv at idle or thereabouts.

just read all this thread and was going to suggest the backfire scenario where the lpg sytem backfires and blows off the idle circuit hose from the flap body. guess not though, and as has been said this set up is probably the lpg with individual injectors. used to see that all the time though with k-jet systems, not always with gas.

Will bare that in mind Alexander as It does have a lambda sensor fitted (must be to control the LPG system)
So Im going to have a look at that myself.

Thanks for the input

Alex.
