Strange problem! Please help!
 

I have very strange problem with my car....
I have RX7 FD3S JDM 99spec...
Here's the problem.
I have bought Mazdaspeed cluster for my car and try to install it, but my car have not start! I try to start it, but it spins and do not start...
Then I have not time, so I just put my old cluster and hold over instalation on pair days....
This pair days I use my car with no any problems....
After pair days I try to install it again and car do not start again....
Difference in this two clusters is only that my cluster have boost gauge, but Mazdaspeed have oil pressure gauge...
Then I try to put Mazdaspeed gauges in my cluster, but car have not start again..
So, then I try to replace all as it was with my old cluster and car have not start!!!
I have checked all that I can:dunno:....
All fuses are good, all relays are good too.. Ignition works good.. cluster works too
It seems like fuel cutoff...
Please tell me how cluster may influence on fuel delivery?
Maybe somebody had the same problem?
It seems like any block system step in...
But I have not any alarm system or something else...
And I have PowerFC Ecu if it matter...
Please help me:(...
Thanks.
