Car wil not stay running

Should be at least 35-45 psi.

should be on the fuel rail, take the plastic engine cover off and you should see the injector rails on either side of the supercharger, got to be real close to the line towards the firewall

First thing I would need to know is if you are loosing spark or fuel pressure when the engine stops.
If it is fuel, it could be the engine oil pressure switch. The fuel pump gets power from the pump relay in crank mode, then from the oil pressure switch once the engine starts.

The replacement of the forward clutch requires the automatic transmission be removed and rebuilt, Cost about $2500.00

can you give more detail did it start to run rough,how much oil is on the dip stick,does it turn over,????

Your fuel pump ballast resistor is bad if it's a super charged engine. you will find it behind the battery other side of the wall kind of hard to find. it's a large white ceramic rectangle this takes the load from the fuel pump allowing it to run.

CHECK FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER.IF NO CHANGE. REPLACE FUEL PUMP.IF FUEL PUMP IS GOOD.YOUR PROBLEM COULD BE A INTAKE LEAK OR SPARK IGNITION PROBLEMS.ALSO USE A SCANNER TO CHECK FOR FAULTY SENSORS OR THEFT DETERENT PROBLEMS.

the answer here is the forward clutch pack is worn out, in order to replace this umust overhaul the trans.

Check the idle air control as it is operating when you start the car and after the car warms up it is out of the system.
