i think the fuel pump has number 99 on it and the ECU as 197 on it.   the ECU is bottom row to the very right and fuel pump is the big one with 99 on it :D

167 and 30 the numbers are, all the relays are on top of the fusebox, you'll need to remove some trim and pull the fusebox down after unclipping it each side

I too had this problem, it would stall all the time then after a while would cut out totally.  Turned out to be the coil sensor pack so the coil was just over heating and cutting the engine.  My local garage diagnosed the problem and sorted it out (new coil and coil sensor). It's been running sweet ever since  :grin:

Could well be, it's not the only thing that can cause cut-outs, but it is the most common. Could be the coil, engine speed sensor, or the ignition switch which is getting more common these days
