Short Money 7.3L No Power, Buzz Test
Picked up a 99 7.3L dump for short money. The issue the owner discribed was no power. I was able to drive it home. It definitely has no power.
It almost feels like the turbo is non-existant. (was replaced by previous owner)
Will not do more then 55-60 just doesn't have the power to get there.
I am assuming fuel related or injectors.
I put it on the AE did a buzz test 2,3,5,7 clearly produced diminished sounds. I wasn't able to start it to do a CCT to see if it matched those cylinders, the batteries died trying to start. It did turn over just was lacking the fuel.
It did throw the following codes P1670, P0475, P0470
I know P1670 leans towards the IDM but wouldnt a faulty IDM produce an all around crap buzz test?
My question is should I just bite the bullet and buy the 4 injectors and fix the EBPV codes and hope thats the cure?
I do plan on dropping the fuel tank and cleaning the screens, also pulled the fuel bowl filter out and it is filthy inside, i do plan on cleaning that as well.
217k on the truck BTW. The previous owner said they replaced the #1 injector and the injector harness.
