Hello, I have been working with my 91 940 turbo. I was able to get to the point where she would start and run with starting fluid, but would later cut off and need starting fluid to restart. I changed the crank position sensor and she would start without starting fluid. About two hours later she was back to needing fluid. Today, I replaced the Radion Suppression relay or sensor by the tower. She once again started without fluid. She ran at an idle for about one hour. She cut off and now she will quickly fire when the starting fluid is added, but will not continue running like she once did. :

-Two new fuel pumps (no fuel pressure at the time)
-New Crank Position Sensor
-New Ignition Amp
-Tested Radio Suppression Relay
-new fuel pump
-all new fuel lines
-Fuel pressure regulator
-new plugs
-new wires
-new plugs
-new air mass sensor
-cleaned idle control valve
-all new vacuum hoses

As you can see, I have invested quite a bit of time and efforta nd am now at a loss. Any help would be greatly appreciated.


Thanks.
