Puzzling question

Okay... thanks. I don't think the dull paint on the bumper would keep it from running, but I suppose it's worth looking into.

Shouldn't be getting spark from all wires and you should have at least one code if the timing belt were broken, but you can look in the oil fill hole while someone cranks it over and see if the intake cam's #1 or #2 lobe moves.

Green & Cre,

Want to thank you for your assist & input so far. I got up late and went to lunch with the wife (killed my morning). Plus I'm kinda draggin' today (over did it - old man thing), so I'm not feeling up to bending over a car. When I start back at it in a day or two (hopefully) I'll update you guys on my progress.

Great meeting you two. Talk to you soon.

Tim

Green & Cre,

I promised you two I'd give an update when felt spiffy enough to work on my supra again.

Update -
Ohmed all sensors, relays, resistors, coils, etc all read within spec.
Compression check all cylinders @ 151-152 lbs.
Fuel pressure & volume fine.
Last thing I did before I quit for the evening was unplug to injector top to the #5 cylinder, metered it to see if a voltage signal was hitting the injector while cranking. No signal. So something is causing the injectors not to fire. I'll try to trace that down tommorow or tuesday if I feel up to it. Already feeling stiff (old sucks!)

Check the Solenoid resistor on the driver's side tire well:

It has power to the injectors. It appears the injectors are not grounding to fire

TSM says the ground (body point B) is on the intake manifold, and for the life of me It can't find it.

At this point I figure it is either a bad ground or a bad ECU not grounding to fire the injectors.

If one ground is bad, it may just be a better option to get a ground out diagram and clean all of the grounding points with a bristle brush or something.
