Bought 2001 Hyundia Sonata 4 cyl with 26k miles, w/ blown head gasket, replaced engine, found that it needed an ECM (computer), replaced it. Car starts up, runs a couple of seconds-makes a chirping sound and shuts off. (have no key fob)
Assume the alarm module is bad (apparently car was under water) How can I disable the alarm? Don’t care about security, just want it to start and run. I can’t find a color coded wiring diagram.
