NEED HELP!!! I've got no oil pressure!!
My motor was just rebuilt on my 03 Evo. My friends went to start it up yesterday and I have 0 oil pressure!!! They took the pump off and everything looks fine, but the inlet line is bone dry. Just tryin to see if anyone has had the same problem or if anyone may have an idea before I just replace the pump all together. Thanks guys!

You need to pack the oil pump with petroleum based jelly (vaseline) when you put a fresh dry pump in a new build. This will help to keep it from wearing into the front case or oil pump case on dry start up and it will create enough vacuum to prime the oil pump. Also, if your motor is built did you do the balance shaft elimination? Did the bearings get turned? If not then you won't get any oil pressure either.

hmmmm.... im not an expert on evos I own a honda, but just throwing things out here, is it the correct oil pump? since you said its new, is the crank spining the oil pump? i dont think not having lube on your oil pump would cause this, maybe theres a hole on the pick up tube where its sucking air from where it connects to the oil pump??? or a warn out gasket of the pick up tube...???? dont turn your car on just prime the motor take the fuel fuse out and crank the car take the oil line from the turbo of and see if its pushing oil or not....

Having a similar issue on my 03.
I unplugged the crank sensor and cam sensor and left the oil feed line on the head loose to see if any oil would come out from the head. I cranked it for a good 15 seconds and I am not getting any oil to the head.
The head is also equipped with a kiggly hla if that makes any difference..
Just trying to get some ideas on what the issue may be. Engine is a built 2.0 long rod..

In the case of oil cooler line, there's a thermostat in the oil filter housing that prevents oil from going to the cooler until a certain temperature is reached.
Did you build this motor yourself? Any chance the oil squirter's not installed properly and leaking pressure? Did you remove the balancer shaft?

The balance shaft is still intact...
