"need help please" ls400 wont spark
Hi guys thanks for reading so check it out one morning I went out to start my car and it just kept cranking. Now so far I've
1:swapped ECU with good one of matching numbers upon close inspection I can see no signs of capacitor leakage nothing to show a red flag no weird smell nothing looks good!
2:swapped igniters
3:swapped coil packs
4:swapped ignition switch complete
Problems so far: No CEL, No power to fuel pump , If I back probe my cam sensor with the test light grounded my injectors turn on lol,No spark from coil packs,
What little I got going for me: I can make it get fuel of course, power to my injectors, power to my coil packs, power to everything just no spark
My sob story: I've been busting my *** on this thing for two weeks I've read every thread of any relevance to my situation slot of people have it nobody has said " Ah HA this is the problem" which worries the hell out of me lol. Like when this happens it's end all **** for the car hahahahahalol any help would be greatly appreciated any solution no matter how ridiculous ( unless it has to do with me dancing in some fashion, chanting some crazy spell ,although it might work , or rubber chickens)So my life sucks thanks guys

Are you sure you are getting fuel ? Not just power, but actually dropping fuel in?
If you have spark at the coils, follow the lead from the ignitor, remove it from the cap and make sure it's sparking.
