Okay I cant seem to get my rebuilt engine running. The engine actually starts for maybe 2-6 seconds but will not go over 1000 rpm and then dies. I have tried this many time with the same results. What do you think the porblem is? I tested for spark and my leadings are firing..for sure. but my trails dont spark but the engine should start them and My RPM ghauge is working so they amust be working. Can this be due to leaky injectors?

 

MAF plugged in?
