QUESTION: what is .7.0.

Answer
.7.0 is the start of the next set of displays that you do nNOT need to get into since you have NO CODES prior to the .7.0.

Take both 2 wire connectors off of the fuel injectors and using a test light which is OK for this test. Ground the alligator clip to any metal surface and check both sets of wires on the 2 disconnected electrical connectors.

With the ignition key ON, You should have battery voltage one one of the wires in each set of connectors. Do YOU ?.

If you have battery voltage on one wire in each electrical connector, remove the ground wire and attach it to the other wire in each connector, One at a time and try and start the car and see if the test light starts flashing ON and OFF in each set of connectors.

IF you have battery voltage one one wire in each set of connectors and when you move the test light ground to the other connector within each connector and you have no test light flashing ON and OFF, Your computer is deceased and needs to be replaced.
