I have a 2006 titan crew cab with an after market car alarm/remato start. Sometimes and only sometime the car will NOT start. What i mean by that is that the car tries to start but will not turn over. Also this only happens once in a while, but it does happen. And let m e tell you this is extremely annoying. I am pretty sure some one will say bring it back to where you had it installed. I DID, and they are stumped, also the place is an extremely reputable place as well. At first they changed out the module and thought that did it, but it didnt. If there is anybody out there that is good with alarms please give me an idea as to what to do.
