Default Re: Vacuum pump not coming on?

Hi Rich & welcome to the Brotherhood!

Okay, not a problem....we're like that in this group. I have software to 93 on primary cartridges and a troubleshooter up to 92 for my scanner.

I would say that from your further description to check that MAP hose. Also, check to see that hose is not full of oil, that happens alot and it can cause the MAP to not get the vacuum input as it clogs the MAP over time. Can you smell it at idle if you give a sniff at the tail pipes? At speed can you smell it in the car?
