Problems Daewoo Lanos del 99

Hello greetings I have worked in Daewoo, look you have to look if pressure arrives at the injectors (to the input tube to the gasoline filter) and if there is spark in the spark plugs. Three cars fail of the camshafts already kpt up and lose compression in the cylinder 4. They can have a problem of immobilizer for it. turn off when you pull the start. Well, those check. They look if that model goes the switchboard under the passenger seat since the connectors are usually oxidized. Well greeting and answer when you know something.

Betis, I have a Daewoo Lanos 2001 Motor 65CV, and for 2 weeks that took it to the Chevrolet to scan the airbag I started to fail my ignition. It starts when you fancy and according to the wind, ... I returned to the Chevrolet the next day since when I removed it from the workshop because of the airbag they gave me with the engine running, but it was to leave there and in the first stop I started to give me that fault to this day. I went back to the Chevrolet but the uncles washed their hands and told me that they had not touched anything about the immobilizer system .... summary they want to charge me more than € 400 to repair me what I want is to sell it and I have a buyer for € 1500, so I am not willing to put that money, since I do not have it and I do not justify it in that car for its sale value.
I do not understand any of this but there would be some homemade way to fix or deactivate the immobilizer, or tell me where that piece is to see if you say, the oxidized condators. Otherwise once it starts it is wondering. It is a good car, only that each one who comes to see and try for the theme of the starting failure is frightened !!!! Help !!!!! Thank you.

I have the same problem I changed my clutch and goes when he wants

Here I have a wool that does not spark

And the steering wheel captor did you check it?
