Help!
So I’m baffled! I can’t get this engine to run as it should. It’s hard starting, smoky, loud, slow throttle response, and has maybe 40% the power it should. The smoke out of the exhaust is unburnt fuel.
So this engine has roughly 10,000 miles on a fresh 1mm overbore and rebuilt head by cylinder head rebuilders in Portland. Ran great when I pulled it out of the car I had it in. What I did when getting it ready for this project; new timing belt, water pump and idler, checked and adjusted valves, and installed ARP head studs.
Before installing the rebuilt injectors I compression tested it, 400-430 psi on all, so compression is good.
I have rebuilt the injectors, all spray and pop correctly, I have checked the fuel lines and fittings several times for air intrusion and have adjusted the timing from anywhere from .60mm to 1.1mm, no change.
I have ran it without the intake, without the exhaust, with the turbo removed, ect, no change. I’m stumped.
I guess I will try a different injection pump.
