Hello all, first time posting here and English is not my first language so sorry in advance if anything is hard to understand.. The car: 1995 G3 ABF (immo digifant 3.2) with stock Climatronic, that is fitted with a LPG injection system - other than that 100% stock from what I know. This is skipable February of this year, the car developed a rather interesting condition - it would idle smooth but first getting it to the idle (900-100rpm) and then going from there till 2000, would require me to jab the throttle very fast (as stupid as it is, the same that Jeremy Clarkson was doing to that RV in The Grand Tour). Above 2000 till 4000 ish it did run and I managed to drive the last 100kms of my trip like that. I couldnt get it fixed myself (plugs, cables, fuel filter, checking the vacuums, coil, temp sensor, relays, throttle position sensor), so during the Covid lockdown it was at my mechanics shop and they got it running with new crack position sensor (Valeo brand), fuel pressure regulator and a used ECU which had the immo disabled. Main problem Few months later (when travel was possible), I get my car and notice the current problem - sometimes, no matter hot or cold engine, it would require a solid 30-60s of cranking the engine for it to fire up with the result of strong petrol smell from the exhaust. Through the ODB and the LPG ECU diagnostics, I saw that whenever this happens, the injectors would slowly go from 22, 19 etc ms till 10 ish when the car goes to 500-600 rpm and requires me to press the gas pedal to go to normal idle speed (1000 ish for cold engine). Now, to exclude the LPG system out of this. Yes, the petrol injector signal wires are chopped and wired though the LPG controller, which enabled me to see their ms times in real time since the OBD is rather slow. Firstly the LPG controller to see these high injector times, would mean that the petrol ECU is sending them and secondly, I have tried with the LPG controller unplugged and the wires bridged - no difference, still refusing to start. At this point basically everything is checked/replaced except the wiring of the car.It has been scanned multiple times for erros and watched real time that the temp sensors read correctly. It does run sort of decent, but this long cranking would just burn my starter sooner or later. We tried new Hella crank position sensor since while cranking the RPM needle would either sit on 0, or swing between 0-200 or stay at 200 (different everytime) - no difference. The engine harness is hardened but the wires still look intact. The only known wiring problem is that once, while trying to get the fuse box back in its place, something behind it sparked. That's the problem, explained as detailed as I can. Any tips for where to look now are highly appreciated since I'm close to selling it and getting something D/TD (have enough of this electrical BS already).
