BluePrint notes that timing should be checked even though engines are dyno tested because components can be moved during shipping or installation. ### ***Is The Battery Fully Charged?*** **A fully charged battery is strongly recommended.** Before startup: - Verify battery voltage is sufficient. - Confirm battery terminals are tight. - Inspect starter cable connections. - Verify starter engagement. Low battery voltage can create misleading symptoms that appear to be ignition or fuel problems. This is particularly important for EFI-equipped engines.  ### ***Have You Inspected Wiring And Sensors?*** **All wiring connections should be verified before startup.** Inspect: - Coolant temperature sensor connections - Oil pressure sender connections - MAP sensor connections - IAT sensor connections (EFI applications) - Injector connectors - Ignition connectors - Grounds Pay special attention to connectors that may have been disconnected during installation. ### ***What Should I Watch During The First Startup?*** **Monitor engine operation continuously during the first few minutes.** Watch for: ### Oil Pressure - Confirm oil pressure appears quickly after startup. - Shut the engine off immediately if oil pressure does not develop. ### Coolant Temperature - Monitor temperature as the engine warms up. - Check for leaks and trapped air. ### Fuel Leaks - Inspect fuel lines, fittings, carburetor, rails, and connections. ### Unusual Noises - Investigate any severe knocking, grinding, or metal-to-metal sounds immediately. ### Charging Voltage - Confirm the alternator is charging properly. If any major concern is observed, shut the engine down and inspect the system before continuing operation. What Is Normal During Initial Startup? The following conditions may be normal during early operation: - Light smoke from protective coatings on exhaust components - Minor odors from new parts heating for the first time - Initial coolant level changes as trapped air purges - Minor adjustment of idle speed and timing If these conditions persist or worsen, further inspection may be required. First Startup Checklist Before turning the key, verify ✅ Oil level checked ✅ Battery fully charged ✅ Fuel system leak-free ✅ Cooling system filled ✅ Ground straps installed ✅ Ignition timing verified ✅ Spark plug wires correctly routed ✅ All sensors connected ✅ No loose wiring ✅ No tools or shop rags left in the engine compartment  - [General Support](https://knowledgebase.blueprintengines.com/knowledge/general-support?hsLang=en) - [Technical Support](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#main-content) - [General Engine FAQ](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#general-engine-faq) - [BluePrint GM Style Engines](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#blueprint-gm-style-engines) - [BluePrint Ford Style Engines](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#blueprint-ford-style-engines) - [Transmissions](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#transmissions) - [Fuel Systems](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#fuel-systems) - [Parts and Accessories](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#parts-and-accessories) - [Carburetors](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#carburetors) - [Alternator](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#alternator) - [Term X](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#term-x) - [Valve Train](https://knowledgebase.blueprintengines.com/knowledge/technical-support?hsLang=en#valve-train) - [Factory Five FAQ](https://knowledgebase.blueprintengines.com/knowledge/factory-five-faq?hsLang=en) - [Engine Specs](https://knowledgebase.blueprintengines.com/knowledge/engine-specs?hsLang=en) - [Discontinued Engine Specs](https://knowledgebase.blueprintengines.com/knowledge/discontinued-engine-specs?hsLang=en#main-content) - [Engine Support](https://knowledgebase.blueprintengines.com/knowledge/discontinued-engine-specs?hsLang=en#engine-support) [![Chill listening crop-3](https://knowledgebase.blueprintengines.com/hs-fs/hubfs/IN%20CRATE%20ENGINES..png?width=92&height=24&name=IN%20CRATE%20ENGINES..png "Chill listening crop-3")](http://navy-blueprint-logo) www.blueprintengines.com Help Center Copyright © 2026, BluePrint Engines
