so I’ve scoured different forums but having no luck solving a hard start issue. Bought a 99 lx470 about 2 months ago. Ran amazing for a couple weeks and still runs great once it’s running but after having it two weeks it would intermittently crank at start but not fire. Turn the key off and try again and it would fire. Sometimes it takes 2-3 tries. Sometimes it fires immediately. I did some regular tune up stuff when I first got it. Oil change/ new filters. Some things I’ve done since the issue started: new fuses at ecu and efi, new fuel pump relay, new fuel filter, cleaned the maf, checked charging system, new upstream 02 sensors. I have a new fuel pump but not installed, the heat shields on the cats are rusty rattling sob’s so it’s possible the cats could be trash and they could be causing the issue. I’ve got no cel though and almost wish I did so it might give an idea what else to check. Maybe I’m overlooking something simple? Any help would be greatly appreciated.
