Volvo penta 5.0 gl- engine won't start

Customer Question

i have a 2002 Volvo penta 5.0 gl-b engine. It's getting spark and cranking. But won't start. If you try to start it for more than about 10 seconds a thud sound comes out of the exhaust. Not really a backfire but close. Replaced the distributor cap and module. But nothing else. So the timing shouldn't have been affected. The reason for the repairs was a battery was hooked up backwards. Before that it was running great.
