Default Car starts idles give it gas and it dies

Hi I have a friend that has a 97 z28 the car starts idles and when rev it or give it gas it dies! We have checked the fuel pressure its fine we pulled the codes and its throwing 3 different codes for crank position sensor so we replaced it and still the same thing. I cleaned the harness where it plugs in didnt help. Also we put my mass air sensor and tps sensor on it to see if it would help nope again. Anyone have any suggestions?

What were the 3 crank position sensor codes?

When you start it whats your oil pressure read?
If you have no oil pressure, the fuel pump will shut off.
The oil sending unit does 2 things, a sending unit and fuel pump switch.

It has oil pressure when starts holds 40 pounds at idle and had around 40 pounds of fuel pressure. Cant remember the codes had a friend pull them.

Oil pressure could be going 0-psi when he accelerates. Maybe a bad sending unit? If not I would think ignition issues.

Could possibly have damage on the crank reluctor wheel.
