how to test fuel pressure? hard start problem
After the car is warmed up and sits more then 30 min, it has a hard time starting. Its a 97 12v v6 a4.
Cleaned ICV, TB, MAF, and replaced CTS. Two separate mechanics said they thought it was fuel related. FUel filter was changed 9k miles ago.
If I get a B&M fuel pressure gauge, what fittings do I need to test fuel pressure, adn where to I tap into. I was to isolate the problem to figure out if its the check valve in the fuel pump, FPR, or maybe the injectors. Car is stock. Also starts fine when its cold or sits over night. Im lost, and I have no CELs. I dont have a FSM either, thats out.
