OK Found the lost ECU, key on and it blinks 3 times then pauses and 3 times again, is it telling me something? I plugged the green connectors together. I run a wire from the hot side of the pump to a 12v light that I had for other testing, to the front seat area, so I can tell when the pump is on,turned key to run the light blinked on & off like you said it should, Checked to be sure that the pump was actualy running, started the motor, it ran (lights stayed on) till it run out of gas and then went back to on & off again. I could hear the relay working so it is OK. Did this several times with same results. Filter seems to be handling enough gas to run my 427 SS so it must be the pump that can't keep up, Huh? Crupper

Thanks, but what is the ECU? I have the owners manual and a Haynes repair manual and it isn't mentioned in either. There is a picture of a ECM in fig.10.21 "Verious under-dash electrical unit locations". It also shows a picture of a Fuel pump control unit, is there a chance it might be the cause of no juce to pump? I haven't been under the dash yet this AM as I've got to dig a grave for the neighbors old dog, she is putting it down today. Many tears. I'll get back to Soobin later today. Is it possible for the pump to run and still not build enough pressure to keep the motor running? I'll pickup a new filter today also. Crupper

Hi everyone I'm working on a well used 90 Loyale Turbo. Installed a used (low mileage) motor from Japan. Got everything swapped between the two so it will run. Had it out on the road and everything working fine for about 3 miles and then it seemed to run short of gas, it would idle and then a short burst of power and back to idle. It finaly quit. I could start it then it would die, now it it won't start. Jumperd the fuel pump, it works but no 12v back there. Been two days looking for the fuel pump relay,no find, can see it on some wiring diagrams. Fuse OK. What am I missing? Thanks for any help Crupper
