Still trying to get my truck going, as after my last thread it decided not to start at all and I can't get it to the shop. I can usually get it to start once from cold, but not enough power to move. I'm trying to find faulty sensors at this point. The voltage on my TPS looks good per the family, but wondering if it's normal for the computer to read the range of it from only 13% at idle to 65% at WOT

 

Yeah, sometimes those readings can seem a little strange..... So long as it is less than 1 volt at closed throttle, and greater than 3.5 at WOT, it *should* be good.

Is it running on all 8? Fuel pressure good? Cat not clogged?

 

All 8 firing, cat is less than 2 years old. Holding good pressure at the fuel rail

 

Fuel trims? About the only other thing I can think of.... How are the O2 sensors? (not that they should matter when you first start it.) Compression?

 

What should the trim reading be? I've never messed with it. I cant keep it running long enough to actually test the O2 sensors. I just a minute at sporatic idle. 4-800 RPMs.

 

Is it a strong blue spark or does it look orange? Not sure what was covered in your previous thread.

 

Should be single digits, or low double digits. If its greater than about 25, in either direction, there is a problem.

 

Strong and pretty and blue. the coil, plugs, cam sensor, cap and rotor were all replaced with the engine or shortly after. I would have done wires but they are already 10mm and still relatively new.

 

I didn't record it on my last check. I'll check it on wednesday when I'm home from work. Thanks for the help.
