1999 S70 T5 ETM and no start?
Hey guys,
Looking for a little guidance on some issues my car is having. I was driving up a serious pass here in Colorado when my car lost a lot of its normal power but I still had enough to get me home. When I would let off the throttle the car would jerk, the same would happen when I changed gears. Around 70 miles later the CEL came on, but I was still able to clip along at highway speeds but did not have the normal "Omph" that the T5 usually has. When I got home I checked the codes. They were: P1283, P0121, and P1171. When I went out the next morning to do some suspension work and I backed it out a bit to get the jack underneath the tach bounced up and down from around 500 to 2000 (about a second each bounce). Now today when I went out to take another look the car won't start at all. I get some activity under the hood, but it seems like it is not getting any fuel (pure speculation). Signs are pointing towards a bad ETM/MAF, but the not starting has me puzzled. Will a bad ETM cause the car to not start? A helpful soul on another forum thinks it may be a bad MAP sensor...It will not start with or without the MAF. Thanks for your help.

I pulled the ETM yesterday and it is a yellow tag (replacement) part. A member of another forum suggested that the non start issue may be "Lawn Mower" syndrome induced when I started and backed it up to work on the suspension. It only ran for about 3 seconds. I am sending the ETM off to Xemodex and once it is back I will put her back together and hopefully I can get it to start.
So after replacing ETM, MAF, TCV, and purge valve the idle will still occasionally dip and then swing back up to a steady 800rpm. No biggie I guess. Unless somebody has more ideas I'll just live with it. Lawn mower syndrome sorted itself out after a couple of days of sitting in the parking spot
