Narrative:

While pushing back from the gate; the #2 engine was started normally. While I was clearing off the ground crew; the first officer (first officer) was starting the #1 engine. The starter valve light opened; however; we received no N1 or N2 indication. Left duct pressure appeared normal. We attempted two unsuccessful starts; never reaching motoring rpm or adding fuel; and I decided to contact dispatch and patch through to maintenance. Maintenance control had me cycle the #1 starter valve circuit breaker and reattempt. Same indication was observed. We were instructed to return to the gate and call contract maintenance.while coordinating the return the #1 engine fire light illuminated. We referenced the qrc and completed the engine fire checklist. The overheat light remained illuminated throughout; resulting in both fire bottles needing to be discharged. I had the first officer call for fire coverage while I spoke to the flight attendants and then made a PA to the passengers letting them know what was happening. After arriving; the fire crews reported no engine fire indication. I elected to taxi back into the gate. I coordinated with the fire crews and to stay and monitor the engine until contract maintenance could open the cowls and inspect. I spoke with the passengers and then called dispatch to relay the events and coordinate further maintenance.
