Toyota Repair: oil pump timing, oil pressure sending unit, toyota celica

Question
I have replaced the oil pump gasket on my 1991 Toyota Celica with a 2.2 engine. I cant get any oil pressure now ,what are the timing marks that I need to put it on?

Answer
There should be a "dimple" on both the outer gear and the inner gear.  These need to be lined up.
First thing though, check your oil pressure sending unit to see if it plugged in and working properly.  This would show no oil pressure if it is not working properly.  Investigate this before you tear into the engine.

Hope this helps.
