    Well. The saga of my TR continues. I replaced the EHA's and she was running fine for a few days. The day before I was scheduled to take her to the dealer to have the banks balanced....I lost power again. I pulled everything back off for what must be the 6th time and found the Air Sensor Plate on the right side to be open and without tension. I thought I had a bad fuel distributor, but after a call to generous gentleman at CIS Flow Tech he told me that it did not sound like a bad fuel distributor but rather a lack of fuel pressure. So I went through my notes on various threads and followed a set of tests 91tr gave for testing fuel system concerns. When bypassing the relay in the fuse box, 1 fuel pump hummed and the other did not. The problem I have now...I did not see a thread explaining what to check next when this problem exists. I won't be able to get the car up on the lift until tomorrow night, so any suggestions on a plan of attack would be greatly appreciated.

    My thanks again.

    Regards,
    Bill

    Without beinf familiar with previous thread, has the power output for the pumps at the fuse board been looked at? Being intermittant is a symptom of that problem.

    Thanks for the quick response.....I just checked the voltage to both relay points and they match.

    Do what Steve said. You did not check the board output.

    Thanks again to everyone. I checked the white plug and sure enough it was toast. Here, I hope, is an image of the damage. I had bought a few of each of these plugs & new clips when I had the A/C issue. So no cost this time around. It fired right up and ran great.

    Thanks again,
    Bill

    FYI- While speaking with the folks at Ricambi I learned they have a number of these plugs in stock.

    At the pace my fuse box is going, I am going to need them.
