i have a 1993 impreza wrx that i bought as a bare shell, afew weeks back i put engine in out a 94 and z4 ecu it turns over but wont fire up, fuel pumps priming, getting power at the coils. i have no power coming off the ecu for the cam and crank sensors or the ignition igniter. i have had a sparky out who didnt have a clue what was wrong please can some1 give me some ideas what i could try next?

This might sound really simple but is the ECU a working unit

chriswhite88

Could just be wired up wrong mate worth another check lol

Could have the wrong timing pulleys on

chriswhite88

checked all the wires mate. the engine had a new belt fitted just fitted before i bought it, was running sweet till it went in my car. have ordered another fingers crossed that solves it

wee update changed the ecu last week car sounded totaly diff as if it wants to start but still not starting checked to see if its getting spark and only seems to get spark every now and then. battery is fully charged. am gona try cam and crank sensors next

Could it be the coil pack

have you checked it's got the correct pulleys on?
If you have the wrong crank pulley or cam pulleys for the ECU it will have different trigger points hence not sparking on time.
