Question
I have a issue with my 1994 Cadillac deville. When I wake up in the morning and go to work it starts just fine. When I stop for gas on my way to work or any where for that matter it cranks over 4 or 5 times very sluggish sometimes sounding as if the battery was near dead but only when hot I've found that when I let it cool down it starts rite up. I have a brand new Optima redtop 1000-CCA battery in it that should be more then capable of starting this car. Every time I have the battery checked the people say the battery is not charging to its full capacity and staying there but the battery and the alternator check out fine. I have to admit that I am stumped and so are every mechanic in the Tampa Bay area. I have spent thousands trying to get this fixed PLEASE HELP.
Hello,
My first concern is you say the engine is hot. If you run this engine over 220 degrees, you will be spending thousands more on that aluminum engine. These engines when over heating litterally melt and you will not find a good engine in a junk yard either. Head gaskets go first, heads, block etc.
Now, are ypu telling me this is a hot engine or a warmed up engine?

Expertise
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?
