Hi Drecko0369,

With a jumper, the fuel pump would be running once the ignition switch is turned ON. The PGM-FI main relay is known to cause non starting and repairs can be made by resoldering the circuit board.

Since relay has been jumped, this is not the cause of the engine stalling. I don't believe that the fuel pump is the cause of the stalling as well.

Stalling during idling are usually caused by low idling speed and this is caused by dirty throttle body and IAC. They can be cleaned by using carb cleaner. Readjusting the idling speed after cleaning should solve the stalling when stopped.

Stalling during driving if it happens only when gas pedal is released could be attributed to the throttle body and IAC as well.

If engine stalls while cruising, check if the dash lights comes on. If no indicatro lights are showing, the problem should be a faulty ignition switch. Servicing the ignition switch is possible but it might not last and you have to be careful not to make any mistake while reassembling.
