Re: Classic Cranks-But-No-Start problem
Found it. Very back of the fuel rail on the passenger side. Hidden under some vacuum lines.
Tried OBD II code reader again, still no codes.
Tested the fuel pressure. When turning the key to "on", fuel pressure reaches about 60 psi which is in the lower end of the range of good values (60-65 for my model year and engine). HOWEVER, after it reaches 60, it immediately drops back to 0. If I'm not mistaken, it should hold fast at 60 psi, right? It sounds like when the key is in the "on" position, the fuel pump spools up and the pressure reaches 60. However, as soon as I hear the fuel pump stop (about 1 second after the key is in the "on" position), it seems like the pressure goes back to zero.
DISCLAIMER: The fuel pressure tester I used came from Harbor Freight and when testing the fuel, fuel did leak between the seals on components of the pressure tester, like between the gauge and the hose connected to it. Is it possible this is the reason the gauge dropped back to 0 after reaching normal pressure? It wasn't much of a leak, but a leak nonetheless.
