OK - 2003 SPI. Replaced engine with rebuilt model. Everything hooked up. Engine cranks, but will not fire. Not cranking slowly, normal. No spark from spark plug when removed and held close to manifold while cranking. Little bit crazy cuz it was running in another car. Is there ground strap other than the one that goes to the one bolt on the starter/block/bellhousing? Not sure where to start. Everything was working in other car. Can hear the fuel pump pressurize when key is turned on. What do I do?
