98 limited gsx mpem fault?

[kallait]

how do i know if my mpem is faulty? i have had my seadoo to 2 shops and no one knows whats wrong with it. they wanna start replacing everything one at a time until its fixed starting with the mem. this could get expensive i think if thats not the problem.
how can i test or narrow my problem down to the mpem? and where is the cheepest place to get a new one?

I don't see a detailed description of your problem.

If you are having problems with intermittent stalling and failing to start unless you remove your key it might be your D.E.S.S. post.

I'd check al your fuses and make sure they are tight.

MPEM's are so expensive I'd try the little things first.

What did you say the original problem is?
