Ok I am at the part in diagnosis of the relay feeds. With no jumper grounded, there's power to the Orange/Lt. blue and with ignition on, hot to the Red/Blk. stripe side. The Pink/Blk. stripe don't become hot unless the jumper is attached. If I'm understanding correctly the tan/Lt. green wire is most likely the culprit (or eec/eec ground) and I need to verify that at this point. Just making sure I don't miss a step as I have gone through this procedure a few times and seem to keep missing something. So far have followed to the T with everything else ok except for the need for jumper as no pump firing on ignition on. Also had a hard time finding a good spot to do the ground to pump resistance test as touching almost any chassis area was not pulling any measurements or jumpy at best. Think I would need to power wash or sandblast under there to get a decent connection (it's fairly dirty)
Thanks again
Be sure all power is off the circuit before making any resistance measurements. Do not touch the metal probe ends while making resistance measurements. It will cause inaccurate measurements.
The tan/lt green provides the ground for the relay coil. Remove the relay and disconnect the computer wiring harness. Make sure you have removed the test jumper. Measure the resistance between a good ground and the tan/lt green wire: you should see an infinite open circuit. If not, you have short to ground or bad insulation somewhere on the tan/lt green wire.
Put one test probe on the tan/lt green wire connector on the fuel pump relay socket and the other on the tan/lt green wire connector on the computer wiring harness (pin 27), you should see less than 1 ohm. An infinite open circuit or reading in excess of 1 ohm means a dirty connection or broken wire.
