I recently installed an HKS 2mm head gasket and now after putting everything back together my oil pump seems to no longer be pumping oil. My oil pressure gauge constantly reads 0. After cranking the motor for quite a while I looked and not a drop of oil was on the cam. I also had someone watching while I was cranking and no oil was coming through at all.

When I removed the cap on the distributor the rotor spins while cranking the engine, this means the oil pump must be spinning too? Also when I changed the head gasket I ended up having to take off the timing cover if that could have affected anything.

Luckily my fuel pump was not hooked up and Im not getting any spark for some reason related to my Megasquirt install so the motor couldnt start and yes the motor has plenty of oil in it. Im not sure where to start looking for problems so any help would be greatly apreciated.

I posted this on the other two major Z forums which I dont usually do but Im going crazy trying to figure out what is going on with my car.

thanks

Was the oil pump re-installed correctly (dots lined up)?

 

yes Im pretty sure? If I cant think of anything else shortly Ill just go take it back out and make 100% sure

thanks

 

if u took the oil pump off and drained the oil inside the pump then it needs to be prime. to help it out the pump should of been installed with oil inside it. the pump is run off chain so unless thats broke it should be pushing oil. lining up the dots gets your timing right.
