Question about 2001 Oldsmobile Bravada
Well, the secondary air intake malfunction has to do with the air pump I read. Water can get into the air pump in some models and the pump would have to be replaced. However, I have heard that some OEM pumps have a short hose that accumulates water sometimes, causing a recurring problem.
Also, there is sometimes a 20 or 30 Amps fuse that controls the pump.
However, I think, that even though they cleared the code at Advance Auto Parts, and it wouldn't start, that the no start condition is not related to the air pump problem, since the air pump problem is more of an emission control to reduce pollution and doesn't feed directly into the combusiton chamber.
I think that you should check the fuel injectors to make sure that they are working. They should click when under pressure with fuel, and allow fuel to enter the combustion chamber.
Maybe check the fuse for the FI or fuel injectors.
It seems like your vehicle is getting spark since it runs briefly when you spray brake cleaner into the air intake.
