no oil pressure??? no speed???(gets to 90mph but takes forever to get there) yes i do have compression, (1990 rx7 convertable)

 

oil sending unit??? That's about the only answer your gonna get with that description. Give us some info man.

 

nope i tryed that....

 

Try a new oil pressure gauge.

 

Have any more info on what the car does?? On my 91 n/a the pressure gauge went out at the sending unit and I don't think I will be able to fix it unless I rebuild the engine. If you want to work on it yourself I may be able to give you a hand seeing as we live pretty close and even go to the same school. Anyways, I know more about the turbo 7's than the n/a's..I've only had the n/a for less than a year.
