Oil pressure sender needs to be open. When its grounded that's when it thinks there is no oil pressure. Same as the coolant level sender. Check the Level sender relay. You should be able to just unplug the level sender relay. There should also be a bypass harness by the bottom of the door you can plug in. Should be a pink and white wire.

Just to clarify, it cranks but doesn't start, or does it start and die after 10seconds? Reply back after you check the above.
