OK, almost 2 weeks ago now, my car started to stall when I was driving it, and I would wait for like 2 minutes and it would start up again. I managed to drive it to the neighborhood mechanics shop, and he told me that it was most likely a fuel pump. It took him 11 days to replace it. the delay pissed me off, but i was happy just to have it fixed.
So today he calls me to tell me my car is done. I go to pick it up and he only charged me $329 which I thought was a fair price for a fuel pump. However, when i went out to start the car, it wouldn't start unless I floored the gas pedal, and then it was running all super mega fucked up like the timing (?) was all off and shit. If I took my foot off of the gas, the car would kill.
Well, needless to say, I was fucking pissed. It ran smooth as a top when I drove it to the shop (besides the stalling problem). So I went inside, and the guy comes out and agress with me, 'yea, it's not working." Then he proceeds to tell me that it's the "mainbrain" (I guess he meant computer) and that he would get a USED computer and install it for me, and that it would cost about $100. He said that the "mainbrain" probablly was sending no voltage to my fuel pump, which caused the pump to go out.
Now, I have several issues:
1) is it possible that the computer could wreck the pump like that? And if so, why was my car running so smooth when I first brought it in to him?
2) I don't put used parts in my car.
3) what if it was the computer the whole time, and the $329 fuel pump wasn't even broken? Now i'm stuck paying for the whole thing?
4) what if he puts in a god dammned used computer and it's still not fixed?
What do you guys think I should do here? Do these problems make sense the way the guy is explaining it to me?
