It's been like that ever since I got it a year ago. It cuts out as it warms up fully 90% of the time (100% fuel related) as i have a LPG system so I can drive the thing(has left me stranded more than a couple of times before I installed it) Sometimes it runs fine on petrol for some time and after i turn it off and then 10 mins later try to start it up again on petrol, it starts and dies almost instantly or straight up doesnt start at all. When it starts it reeks of petrol and dies like 5-10 secs later. When i switch to LPG it just goes and i have zero problems. I want to be able to drive the car normally on petrol as well(when it goes it goes very well), so I have done quite a bit of work on the car, namely: No error codes whatsoever Replaced lambda Replaced CoolantTemp Sender two times already(not OEM, new, cant find OEM) Replaced plugs two times already Replaced ecu with a digi 3.0 - same prob Replaced dizzy/cap/and the thing that distributes the spark as well(cap and rotor I guess new) Replaced Crank Position Sensor (new, not OEM) and didn't have a torque wrench as i tightened it, made no difference to original OEM one Replaced Fuel Pressure Regulator with Bosch OEM new Replaced Fuel Pump with Bosch OEM new Tried 3 different coils with no result Replaced Fuel Pump Relay and ECM Relay Checked timing and it was a tooth off, timed it right but same as before Checked fuse relay box - took the thing off and apart to make sure - looks immaculate. Checked grounds - all checks out I havent messed with the knock sensors yet, that is litterally the last thing that comes to mind, but it wouldn't cut out the starting. P.S. as it cuts out in driving, tacho still works, switch over to LPG and away you go..... Im so sad as it's running like a 115HP GTI with the LPG system, not the 150 16V i'm searching for. Any help will be highly appreciated.
