Hi all,
Wondering if anyone has come across this issue after their vortec swap. When starting truck either cold or hot i turn the key and hear fuel pump run for 3 secs then go to start it and it kicks right over and goes to approx 1k rpm then dies instantly. Repeat procedure and truck starts fine and runs without a hitch. This has only developed in the last couple weeks after approx 1k trouble free miles. Motor is a 2004 5.3 using a trickflow fuel pump TFS-25004P followed by a WIX 33737 fuel filter with return line back to tank. Fuel is supplied from new outlet installed near bottom on side of tank and return line goes into the top of tank. I am going to put a pressure gauge onthe fuel rail to see if it stays at 60psi first and then go from there. Any ideas would be greatly appreciated.
Brian
