Thanks for the diagram The pin locations made checking easy. All the sensors and wires tested fine yet I still have no temp reading. I would like to know where you got such a good diagram so i can get the same quality info. would you happen to have a diagram showing the wires and pin locations going from the ECU to the digital dash cluster. The cluster unit itself works just fine and it still wants to die on me after about ten min of running. I'm still waiting on the pressure gauge I ordered but I noticed that it loses pressure as soon as I turn the key off. I double checked the lines and no leaks and just replaced the FPR. I'm confused I can hear the fuel pump working but it sounds different than it used to, Do you think I need to replace it? I ask you this only because I got laid off and $100+ per part is becoming a huge financial burden on me. All I want is to get my only vehicle to run reliably enough to get me to work.
