It helps to post the engine, transmission, rough mileage, etc.
Is there any kind of aftermarket intrusion/theft prevention system?
Does the starter engage and turn the engine?
If you get nothing on the key, it is likely to be an interlock, or the ignition switch which a !#$!@#$@# dealer swore never fails.
If the engine turns over, does it do it at normal speed, or very slow?
[battery, grounding, starter drag, cables]
Does the engine fire at all? [lotsa reasons from cps on...]
Does the engine start and then turn right back off [fuel pressure sensor]
