| RE: DIY: Hopeless project. 
					Followed your advice and bought a new cirka OEM spec pump from reputable manufacturer, 5 bar and 100lph, costed me 300E but whatever, I can just bring it back if it breaks etc. Fuel pressure is back, but new symptoms appeared: No spark, and plugs are not wet (Maybe theyre not supposed to be? They do smell fuel) Tried a set of brand new Bosch plugs, the set of NGK`s that I`ve been using, AND the Denso set that was in the engine when I bought it, all of them seem fine but alas.. Now and then it sounds like she gets spark i.e a single cough, but she wont start or anything, I get RPM signal though, so I suppose igniter is good? Test light on W-pin with diagnostics bridged shows nothing. Just to have it covered I made new earth for the coil/injectors/ecu on engine intake, and to be sure I made a new harness with new 12v relay for coil and injectors from ignition, but the symptoms prevail. Again I checked resistance on coil, plug wires, dizzy cap, rotor, tps and most other components covered by the manual, and also made sure the distributor was centered on marks with engine in TDC, compression is good also. As usual, all components are apparently well within OEM specs. Edit: Tried filing the Coil bracket and engine bay metal shiny where both contact, in a bid for good earth, but alas no cigar. Reverted to old alternator (I`ve tried a 20v alternator in it in hopes the voltage might be bad, no difference though), still wouldnt start. Changed fuel pump to the one I currently have, still wont start. Reverted to old coil and igniter, still wont start. I even kicked one of the front tires and spun around 360 degrees for extra rainbow tofu luck, still wont start  So no ECU codes, but no spark, no fuel to cylinders. This all started with me leaving the car at home for a month, coming back home and started her she worked perfect, but as she got warm, the idle went super-low and she stalled out, started her back up and did my round around town the ignition got worse and worse, barely limped back home on super bad Rotary style ignition. Then I changed coil+igniter for another 2nd hand item, she worked for a little but was running super rich, I passed my house on the way home after a test ride and she stalled further up the hill here, I managed to roll back home thanks to gravity. After that I could start it sporadically (every time I started was because I made new earth here or there, changed ignition items here or there etc, now all ignition components are new except coil and igniter) and in the end she wouldnt start even when I reverted the changes I made etc. As I mentioned, I went over to a 20v alternator and re-did the alternator wiring, she still wouldnt start, so the next day I recharged the battery (Almost no voltage lost) and still would not start, then later that day she started like lightning out of the blue sky, she idled for 50 seconds, went down to 200 RPM, then back up, then stalled, so I restarted her, same thing, 50 sec idle, 200 rpm, back up, stall, I`ve never got her started again no matter what google/forum/top dollar advice I`ve followed. Is there any way to use a multimeter to find out if igniter is bad? I`ve tested the coil (and it`s VERY good according to manual) but ECU gives no Error code on Igniter. 1x AE86 84` Zenki Coupè Levin 4A-GE 20v 1x AE86 83' Zenki Coupe Levin 4A-GE 16v 1x TA60 82' Sedan 2T 8V 1x TA40 78` MK1 Zenk/Pre-Facelift Wagon 4A-GE 16v | |||
