Ok where do I start. I have a s70 t5 It will start run for about 10-15 seconds and cut off. I've changed the flow meter fuel pump and relay still doing the same I haven't got to the ignition coil yet (msd) and I'm wondering if the turbo timer that I really don't need might be my issue. The speed sensor has also been bouncing around in my head as well. Any body think they might know before I start spending money on parts.

 

What year is the car?

 

1998 s70 t5 5 speed has me stressed lol.

 

This may be a slight "lawn mower syndrome" issue. I suggest that you do a compression test. If the compression is low, put about 1 oz of oil in each cylinder and start it up then drive it around the block. Should reseal the pistons and keep it going forever.

 

Will it restart each time and run for 10 seconds each time?

 

Book well finally noticed that the crankshaft sensor wire was pinned behind the torque mount bracket pinching it between the head and bracket causing it to short out. I got the car started and running, drove it today. I have to change out the plugs still has a minor misfire. Overall it's running again after 3 days of searching.

 

Thanks for the help @rspi

 

Oh Jeeeez; not LMS again!!
