What would be symptoms of a transfer pump loosing pressure? I know I need to check my pressure to see what it is actually pumping, but thought I would see from others what the motor acts like when the TP is going.
I am having these issues: turbo wont push more than 22 psi even under load(waste gate set at 36), egts never get over about 950F even when floored, doesnt have much power when under load, star turned all the way forward and it barley puffs black smoke. I have recently replaced the over flow valve and that wasnt it.
It just sounds like a fuel pressure issue to me. If it helps the truck has around 165K.
Any ideas???
