You could have several problems.
First I would check the pressure after the regulator. Get 5 or 6 ft of 1/4 plastic tubing. Attach it to the gas line at any easy spot to reach. Pure some water into the tubing and form the tube into a loop with the water coming to rest in the loop. Now turn the gas bottles on and measure the difference between the water in the 2 sides of the tubing. This should be 11 ins of water column. You have tested the regular.
If this check out OK move to the stove. If not adjust the regulator to 11 ins.
At the stove check to see that the proof of flame, thermocouple, is in the pilot flame. If not move it into the flame and try the stove again. If the thermocouple is in the flame and the stove still will not light it may be dead.
Also at the refg. make the same check of the thermocouple. If that is OK remove the burner tube and check it for a spider nest. They love to live in these tubes and often cause poor or no flame problems
