Can’t get into ecu to read if it’s set up in there but I’d say anywhere from 25-35° cool outside but hot in the shed after abit, any way to test injectors? Family member asked if it has a cold start injector like his VL had, Is the cold start valve possibly staying open?

Couldn’t hear factory pump prime, plugs weren’t wet, replaced with new pump, can’t connect to ecu, unsure if it’s because it’s so old and no latest software updates or plug in ports damaged internally, bought a new cord to connect and no luck (EMS 8860). have tried letting the car idle and taking out coolant sensor all that happened is it idled abit worse but didn’t die. Also let car idle on the maf that was on it when I bought it, in plugged and car still ran, swapped with another pink maf, unplugged on idle and still ran, cleaned o2 sensors and car ran at 0.80 Lambda instead of the usual 1.0, after starting it this afternoon the afr guage reads ‘rich’

Hey guys have a 94/95 33 gtst with a rb25det in it, stock apart from, fmic, Toyota Yaris coil pack mod, ems 8860 computer, 3inch exhaust, walbro 255Lph pump. now to my problem, 2 weeks ago I wasn’t getting any luck starting the car, bought a walbro 255 Lph fuel pump installed that, still had no luck starting the car, replaced coil pack plug connectors and remade the harness, car now starts yay but it idles very very rich, Tech edge Afr fuel guage reads ‘rich’ lumpy idle heaps of black smoko coming from the exhaust. Installed an adjustable fuel pressure regulator set the psi to 20, car ran a lot smoother but still read ‘rich’ on afr and black smoke out of the exhaust, have changed the spark plugs over, have triple checked vacuum lines can’t find any unplugged or splits in the lines, cleaned iacv, cleaned maf sensor even tried a friends still didn’t work, does anyone have any ideas of what it could be or where else to check I’m losing my sanity, cheers heaps
