Cranks but won't start
My '99 F250/7.3 wouldn't start yesterday. Engine cranked over, but it wouldn't even try to start and my ABS light came on. I checked battery voltage-12.47 and 12.32. I put a battery charger on for a couple of minutes and it started right up. Charging voltage was 14.6. I tried chargeing the batteries, but engine would not start with out the charger on. Bought new batteries...ABS light went out and It starts just fine. FYI

Same thing happened to me last fall. I thought it was weird how the engine cranked over so quickly, yet the engine still would not start. Apparently the batteries need quite a few amps on tap so the inverter can make 120volts AC for the injectors to operate while cranking. I'm glad to see you replaced both batteries though. Some people replace one at a time, which doesn't make sense to me.
Anyway, good to hear you are back on the road. Thanks for sharing the info.
