So how about a step by step on the SAI air pump replacement? If someone has already done this it would be great to have it posted! I havent been able to find one, and I am about to replace it next week. Does anyone know how hard it is? If I can't find someone who can post it I will try to take good pictures as I go and post them with just how I did it. I really hope its not more than I can handle! I replaced the SAI valve and blew air with a compressor while using my shop vac on the other end hoping the pump could be saved, but it is not sucking hardly any air now and the check eng light came on again. I know with my fat hands just getting the hoses taken off to drain the water from the pump was hell! I am not sure how I will manage getting the whole thing out unless there is a trick I am not seeing. I have to take it in to the dealer next week to get a by-pass on the communication unit(onstar) in the trunk that blew ($190.00) and another key fob made($135.00). (down to one and I hear its pretty salty to have the car reprogrammed for all new keys if we loose this one.) So with already having to spend $325.00 plus tax for those I am not looking forward to spending a ton more. Price at the dealer for just the SAI pump is $372.90. Is that a fair price? I have looked a few other places, but havent really found one that would be any cheaper with shipping. I am going to call today when they open to find one what it would cost to have them replace the pump, but this would only be a last option as I would like to save some cash. Any help would be great on how to tackle the pump! Thanks!
