obd0's just blink codes no long and short flashes like obd1

replace the vacuum line going to the map and check for 5 volts at the plug going to it with the ignition switch in the on position,

starting problem -first check- start your car for about 10 seconds and with the ecu flash any code, shut the car off, take out the key and see if the ecu is still flashing, if so you main relay is sticking and is draining the battery
