Narrative:

'No start' #1 engine start. Accomplished 'no start' checklist. While ground crew was concerned about a 'fire' and captain opened his window to view 'fire,' I talked to passenger on PA. In the middle of telling them about problem, captain initiated evacuate/evacuation. Cabin was evacuate/evacuationed through right side of aircraft (doors 1 and 2 right) with no injuries. I was last person off aircraft. The captain was not around, so maintenance person and myself went up slide back into aircraft, removed slides, and sat in flight deck while B737-500 towed back into gate. People came back on to remove belongings and I left aircraft. Good procedures, but I don't believe captain should have initiated evacuate/evacuation for contained tailpipe fire. Supplemental information from acn 340034: #1 engine stabilized at 28 percent N2 with no egt indications. We began the abnormal start procedure, continuing to motor the engine for 60 seconds. I instructed the first officer to send fire trucks. No cockpit indications of a fire. The abnormal start checklist was not completed. The cabin evacuate/evacuation was accomplished in an orderly fashion, without injury to passenger or crew.
