Hi all I've got a 93 wrx that's just decided it don't want to start anymore turns over but won't fire up I've got fuel and spark checked all fuses was thinking cam or crank sensor but is there away to test them before buying new ones as there expensive car ran fine until few days back the car does have a few modifications and has been mapped with alkatec ecu I've tried the old ecu to see if it was because of the cold start but still won't start any help would be appreciated thanks

 

Try putting in the old/original ecu. Try and start it. If it dowesnt start use the diagnostic connectors under the steering column to check for codes. Do this just to see if it stores any codes.

I've tried the old ecu still won't start and there are no codes stored was a right pain to get the the connectors don't think they have ever been used was still taped up to the top

 

Has it been running ok since the mods were fitted, I saw a old post about the new injectors and that starting problem.
