Now I'm wondering which pump you meant. Inj pump or lift pump? I think you want me to test the lift pump? That makes sense.
I aslo took the fuel shutoff solenoid out and it was not stuck. Pic below is the way it came out. With a Mightyvac on it, it retracted.
I took a compression reading alsoand all cylinders are 320 psi (cold obviously) except the one closest to the firewall which was at 380 (is that cyl 1 or 4?)
What is the easiest way to determine if the inj pump is actually turning? I understand it is driven off the vac pump gear through a dowel? Is there anyway to check w/o removing the vac pump (which is ok btw)?
Before I forget, there was a bit of black stuff on the banjo return fitting which is either algae or bacteria? I wonder if it is blocking some passages in the IP? There is a small banjo fitting on the IP near the lift pump which I believe is the lube for the IP. I will take that off and see if oil squirts out to rule out IP lube starvation.
