We are having a problem with our Tahoe. We have replaced the fuel pump and fuel filter and there is a spark, however there is no fuel getting to the intake. The truck it turning over fine it just won't catch.

Hello,

This could be due to a faulty fuel pressure regulator.
If the pump is good and the fuel filter is clean and there is no clog or blockage in the fuel line the issue is likely a bad fuel pressure regulator.
The regulator is located on the fuel rail (see diagram below).
A faulty regulator can restrict or stop the flow of fuel to the injectors.

This vehicle should have 55-62 PSI of fuel pressure with the key on and engine off.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
