I have no power at the pump.
I have 12.4 volts at pin #13 on the relay board. No power at pin #5 or 7, old eyes can't see the stripe colors very well. Fuses are good. Am I missing something? Thanks in advance. |

Well, here is the final answer - I think.
Thanks for all the diagnostic tips, tried them all. The answer came from the 22 step diagnostic that Olympic 914 sent. http://www.google.com/url?sa=t&rct=j&a...S8A4uDTjQ-CvZDQ I started at the beginning and got positive results until I got to number 21 (skipped the ones referencing the ECU): Fuel pump harness to relay board. No power. I removed the terminal at the end of the fuel pump wire, still no power. The board tests OK - no resistance between relay and pin 13), so plug half of the 14 pin connector is toast? I'm not sure what to do next, for now, I'm running the pump off a switch power fuse. Thanks for all your help. |
