Vehicle mechanic struggles to diagnose a no-start condition after replacing fuel tank and pump on a 1988 Ford E150, with fuel not reaching the high-pressure pump.

Workarounds Described

• blows compressed air through fuel lines to check blockage
• uses junkyard parts to avoid aftermarket sketchiness
• replaces parts sequentially hoping to find the issue

Implied Software Gaps

• Diagnostic software that provides systematic troubleshooting steps without requiring internet forum posts
• Mobile app that logs test results and suggests next steps based on observed fuel flow and pressure

FuelSys Diagnostic Pro

A mobile app that guides mechanics step-by-step through fuel system diagnostics for older vehicles. It provides vehicle-specific wiring diagrams, fuel pressure specs, and a decision tree based on symptoms and test results, reducing guesswork and parts swapping.
