I have a 1999 f-150 with a 5.4 It has a remote start as well. Last week It sputtered and stalled once but restarted instantly. Then a few days later it wouldn't start at all. I would turn the key and on the instrument panel the theft light would flash... the odometer would look like this .......... and basically wouldn't run. It wouldn't start with remote either. I tried another key and still wouldn't start. I let it sit for 15 minutes and it finally started. It ran good for a week but did it all again today. Has anyone heard of this? Do you think it might have something to do with the theft system? How about the remote start itself? maybe it is screwing up. Anyway... I could use a little help. Thank you

Sometimes this is an indication that the battery is starting to go bad, loose wiring or corrosion at the terminal connectors. You might want to take your truck to AutoZone and have them test the battery and alternator, and run the ECU codes for free. Please let us know if the tests don't help in pinpointing the problem.

Not to knock Malibu but that is not a common battery issue. Usually if it's a bad battery you will have a really hard time starting you will notice slow cranking speed and a low reading on your trucks insturment panle voltage meter.
Run an ecu test see what codes come up, codes are kept in the system for a long time. Chances are you will find that it's most likely going to be a sensor or wiring issue.
If you are noticing slow crank speed, check the battery. Also take into consideration that if that batteries the stock one and it's never been serviced. (Water topped up, terminals cleaned, the usual) Then Yes the battery is most likely on it's last leg's. If you find that the battery is newer, with no corrosion or anything and cranking speed is normal it is safe to say the battery is still good.
Batteries don't usually show signs of going bad, with the exception of slow cranking speed or waking up in the morning of a really cold day and it's dead, then you know it's a toast battery.
As for the alternator. As I said before if it is a newer battery that doesn't seem to be holding a charge then it's the alternators fault. Time to rebuild or buy a new one.
But, from what you have described to me, I would say that it seem's like a sensor issue with the remot starter system, or maybe just a sensor issue with the starting system. As the ECU will erase codes after letting it sit for a few minutes, and it will log a fault in the system somewhere.
Hope this helps.
Just for the record, letting a vehichle sit for a few minutes then trying again does not do anything for the battery which is why I am ruling it out. A battery to charge, needs an input voltage from the alternator or generator system in the vehichle.
Thanks Morgan.

No offense taken.  However, I didn't say is was a "common battery issue" - only that it can "sometimes" be the problem. A battery that is "starting to go bad", loose or corroded battery terminals, or an alternator that is starting to go bad can definitely cause intermittent starting problems. Oiler's problem is intermittent. An anti-theft system can also prevent starting if it detects low battery voltage. I've had this same problem on 8 occasions with my numerous cars over the past 24 years. That doesn't mean it's his problem too, but it shouldn't be ruled-out as a possibility.
