SRS light on and stays on, with codes P0102 & P0121
 

SRS light just came on the other day on a 2001 c70 and pulled codes

P0102= MAF or VAF a circuit low input

P0121= TPS/Pedal position sensor a CKT range/performance


Not sure why the SRS light would come on for those codes
But Any suggestions or advice would be greatly appreciated, Thanks!!

Doubtful it would. The code reader you are using even capable of handling SRS codes?

01 c70 coupe engine wont start, takes 3 to 15 cranks now!!
 

Okay, I see your point mkc70...
now my second problem is my 01 c70 coupe, it will crank like it's wants to start but doesn't, sometimes it starts right up, other times it would usually start up on the third try everytime but now it's getting worst and I bought the car in Aug 2010 and so far changed:

1.) Crank sensor
2.) Cam sensor
3.) Spark plugs
4.) Ignition coils
5.) Fuel filter
6.) Maf sensor

Any help or advice would be greatly appreciated, thanks!

That's quite the list of replaced parts you have. Just going by your list I would also consider immobilizer, electronic switch of cylinder, and starter in that particular order. May be beneficial to have dealer assistance or a independent shop with a mac daddy code reader.
