This is the problem.
The car was not driven for a year, ( I was in Afghanistan fighting the war).
When I returned I gave a boost to the vehicle.
Once I did that my check engine light turned on.
I have a gauge that monitors the voltage on the vehicle.
When I turn on the vehicle the gauge reads 12 volts with the brake and battery light on.
Once I am on the road driving, the volt gauge jumps from 12 to 14volts.
At 14 volts the brake and battery light turns off.
Then the it goes from 14 to almost 16 volts and again the brake and battery light turns on.
I replaced the battery, spark plugs and wire, also the alternator.
Now the check engine light was cleared.
But not for long. The check engine light came back on.
When I turn on the vehicle it goes again to 12 volts.
I have a to rev up the engine so that the voltage can stay at 14 volts.
I took the car to where they checked the electrical part of the vehicle and they said that after trying three diffrent machines they could not talk to the computer.
And that is when they said that I should replace the ECU.
Thank you for your time and advice. Please help me.
