I have a 1990 Toyota SR5 4x4 pickup, 3.0 liter. After running, if you stall the motor, especially when warm you have to wait 5 minutes before it will start. It does not quit while running or if you let out the clutch and it stalls, you have to wait 5 minutes or so before it will start. I have put in 2 distributors, new coil, new ignition module, spark plugs and wires, battery, computer rebuilt/checked out and still have the same problem. HELP!
