Default can you test an ECM?

My 98 beetle quit me last week driving down the road. I am not getting the glow plug light to come on. I have tried 2 new 109 relays neither one worked. I was wondering if my ECM could have taken a crap?

You need to find someone who has a test ecm. Your 98 ecm is different than 2000 and up. It probably lisn't the ecm. Did you do all the checks on the troubleshooting guide? Do have a trusted mechanic in your area? Make sure you are getting voltage to the wire on top of the injection pump just above the 4 steel fuel lines. How many miles on the car and has the timing belt been changed. Will the engine turn over or just turn over and not start?
