Cadillac Repair/1998 deville


I ran out of gas and put about 4 gallons in the car then used carb cleaner and it started but would not stay started seems as if the battery may be looseing power cause car wold not turn over after 4th try i just bought car help ???

Fuel injected vehicles can be subject to problems when driven until the tank is empty. Everytime ignition is on and engine not running, the electric fuel pump is runninig. What commonly happens is the fuel pump while on having no fuel will suck air (cavitate) and burn up. The fuel tank has to be removed to replace the pump.

Without being at the car it is impossible for me to confirm this event in your situation, but your discription would be consistent. As for the battery there are too many variables I can't consider without being at the vehicle, however it is not the source of your problem.
Your discription leads me to believe it is a fuel delvery problem if the engine runs with the carb cleaner. I believe you need a fuel pump.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
