Have a question, is it required to flash the existing Computer if I replaced the engine? The car started right up drove it for about 10 miles. Came home and let the fluids cycle for about 30 minutes. The next morning took for another test drive and car started right up however about mile away started to feel funny. Took it home and turned off, now car will only click and will not turn over. Then will completely loose power altogether. Any suggestions before I invest more money blindly.
