During preflight; I noticed a previously cleared write up regarding the airspeed indicators in disagreement. Shortly after establishing takeoff thrust; the ENG light illuminated on the FO's 6-pack. I looked up and noticed both EEC's on the AFT Overhead panel had their amber ALTN lights illuminated. Thinking this was a computer glitch we could possibly solve in flight; I called out CONTINUE and we proceeded down the runway. I have a sense for when I should call out 100 knots and noticed that my airspeed indicator was still at zero (really pegged at 60) while the FO's was approximately at 100 knots. At that point I elected to initiate a rejected takeoff and called out REJECT REJECT. I took over control of the aircraft and the AUTOBRAKES kicked in. I also verified the Autospoilers came out. We rolled to a stop around taxiway Foxtrot. I got clearance from ground to park so we could run the rejected takeoff checklist. No need for an evacuation and the brake cooling chart indicated 32 minutes and not in caution or warning blocks for our weight and speed. Aircraft cleaned up and headed back to the gate after I called the FA's and made a short PA.
After advancing the thrust toward takeoff thrust and calling; 'Check thrust;' we positively transferred control of the thrust levers. Shortly after this happened; the MASTER CAUTION and ENG lights illuminated. We noted the caution and the Captain stated 'Continue.' Prior to the '100 knots' call out being made; the Captain noticed his airspeed indicator didn't have any forward airspeed indication (still indicated 60 knots) and was in disagreement with my airspeed indicator; which was approaching 100 knots. The Captain then stated 'Reject; Reject' and proceeded to reject the takeoff. The aircraft stopped under RTO braking and auto spoilers. We cleared the runway without incident and were able to run the rejected takeoff checklist and begin our return to the gate without further incident.
B737 flight crew reports a rejected takeoff at 100 knots when the Captain detects no airspeed indication on his side. ENG lights had illuminated early in the takeoff roll with a Master Caution but was ignored.
