    No start. No prime. No power at ignition trigger wire fuel pump relay.

    87 Town Car was running fine, parked, shut it off, nothing noticeable, went into restaurant, came out, turn key, no prime, check fuel pump relay, power at yellow wire, no power at trigger wire, pressed inertia button down still nothing, swapped ignition switch for a known good one from my original column still no prime/no trigger, good power after fusible links with probe light, ground eec self test connector no prime, cycle key forward very faint barely audible relay click,

    Bad ecu?
    Bad eec relay?
    Bad inertia switch? Does the inertia switch interupt the ignition trigger wire if it flips?
    Tfi module related?
    Ignition coil connector related?

    What do I Check next?

    Photo of my relays below
    Which one is which? Which is eec relay?
    I do see a bare spot on a wire at that gray connector

    EEC relay should have a red/green wire going o it. The fuel pump relay should have a fat orange wire going to it and the remaining one should be ac wot relay.

    You can apply 12 volts to the orange wire at fuel pump relay to see if the fuel pump engages. This can tell you whether it's the pump or safety shut off. Or if its the relay or an EEC power problem.

      Thanks. Headed back to test 4 things.
      See if it enters a koeo self test,
      Check for spark
      Check for power at inertia switch
      Run 12 volts jumpered to the fuel pump wire to prime

        i might start at cleaning the battery terminals, make sure the little wire connected to the neg cable is good and intact. if memory serves me right the computer controls ground.

            the relay is powered off the positive post on the starter solenoid. more than once I have experienced problems with the power wire corroding and breaking inside the insulation or be loose in the ring terminal that bolts is to the positive post.

              Eec relay has a constant hot and a key on hot. Eec relay ground is good too. Everything looks good at the connector but the relay is not clicking therefore energizing I conclude. Pulled it out, and its all corroded as well as the connector terminals. Replacing momentarily.

                I'm just wondering where to begin if I put this new eec relay in and I still get nothing. Theoretically that should not happen, but we'll see.

                    I'd also be looking at replacing those connectors. I see bare wires going in there.

                        the one by itself is the AC WOT cutout relay. The other two are fuel and EEC, but I can never remember which is which.

                            the one with the yellow-blue jumper wire (that fat one from one leg to another) is the horn relay.

                              must be a different design on the horn relays on later cars. My 86's horn relay is all metal and screws to the inner fender.
