mcx trx starting issues

[northern summit]

My trx started to have strange starting problems. It will always fire up then shut down within a second or two.Sometimes it will do it more than once? It always runs fine by the second or third starting? Anyone have any ideas?

Maybe a fuel pressure issues.

I will look into that.My mcx kit is about 5 years old are these pumps known to fail or not maintain pressure? I will check the presssure.My second blow of valve is a crappy turbosmart with the heavy brass piston
it might be leaking,causing a lean condition.
