A burnt valve (or the dreaded dropped valve seat, a common problem on the Type 4 motor) could also cause your problem. If you have access to a compression tester, use it now. If not, try process of elimination. You can definatively test whether the injector is spraying by physically disconnecting it from the manifold, and holding a rag around it while someone starts the engine. Be ready to yell as soon as it sprays (if it sprays). Either it will spray fuel or it won't. If it does, then it is likely that neither fuel supply nor spark is your problem. This points towards an internal engine problem, and, unfortunately, bad news. Good luck... -Ron Salmon The Bus Depot http://www.busdepot.com
