Do It Yourself Diagnosis and Repair

Could be a bad battery but I suspect your battery cable is either loose or corroded or dirty. Before you pull the battery disconnect your battery cables and clean them both ends and when you put them back on make sure you have good connections and tighten good.If that does not work pull your battery and get it tested at a battery out let . they should do that for free.

Verify at least 12 volts at battery. Depending on car we could be dealing with a security issue with a light flashing, or a bad solenoid or starter.

Try to discounted the bat for 15 minutes that should work

what about your security system? Is the security lamp on the dash on of flashing? If it is your security system, I doubt I can help you from here? Any applicable trouble codes?

Battery has a full charge? Sometimes the battery gets run down from testing?

The asd relay supplies primary voltage to fuel injectors--coil pack and other, engine cranking. The computer usually has to see both the cam and crank sensor signals or it won't ground the asd relay. I can only make suggestions on what to check.

The red circle means there is an intermittent problem with your vehicle security.If your car starts and runs fine it would be hard to diagnose until it wont start at all.

This MAY be a problem with the bcm (Body Control Mod) This electronic part controls these things, Cost about $110.00 But the kicker is you have to find someone with a Tech computer that can Flash it with your cars ser # and Code, try to find one in junk yard (cost / plus is it any better than the one you have, is a gamble). Check the web for info on your bcm problem, It is loacted under the dash up top kind of hard to get to.

have checked the starter, if it clicks, but no crank, that is a starter, if cranks, but does not turn on, that could be a bad battery. ( assuming you have gas )

11= Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking for dodge odb readout. Hope this helps.
