Ford Transit-250 cranks but does not start despite spark and fuel pump operation on Ford Transit-250

Some Ford Transit-250 owners report experiencing difficulties when their vehicle cranks but does not start, despite having spark and fuel pump operation. These issues could stem from a faulty Pressure Relief Valve (PRV), which may cause fuel to leak through the return line, preventing the necessary fuel rail pressure for starting. Additionally, electrical problems such as a dead or low-charged battery can hinder the starting process, and testing the battery with a voltmeter is recommended. Owners have also noted that corrosion or poor connections in the wiring harness connector can lead to starting issues, suggesting that cleaning and securing these connections may help. Furthermore, problems within the fuel system, such as a minor leak or improper installation of the fuel filter, can also impede starting, and ensuring the filter is filled correctly is essential. Lastly, verifying that power is reaching the fuel pump by checking relevant components can be crucial in troubleshooting this issue.
