I purchased this car and I bought a battery, put it in and nothing happened, It just lit up dash lights. The guy said, it was the ignition module, but I do not want spend money on a process of elimination, I paid only $300.00 for the car, I would just like to know where to begin.

A scan would be a good place to start looking, check fuses as well, does it crank over? Do you have spark and fuel pressure? Any extra info will be great, you say you only paid $300 for this car, I am wondering if that is telling you something as well.

It's a no crank, no start, the guy flips cars from the auction, & the city was coming to take them the next day, due to, too many cars @the home, & where due I get a scan?

Every work shop can do it, it takes 2 min to scan, but as the car wont go, you may have to go get a cheap generic scanner and do it your self, problem is the cheap scanners will only give limited info, check for power at the main starter terminal, this should be constant 12V and power at the small starter solenoid wire with the key on crank, if nothing there, may be a transmission range switch or a deeper problem with the PCM, but I would start with a scan first.
