    1983 mark vi not starting

    ok guys so my amazing 83 lincoln is still messed up. Before it wasnt letting the parking lamps turn off. posted on here found out i was running the wrong relay. Right after my dad pulled a relay and sent it down to me she just shut off driving to work. So heres what i know so far.

    Will crank all day long and not start
    Fuel pump is not getting power. hot wired fuel pump to make sure it still works. fuel pump works but car will still not start.

    I've replaced both relays on the fender now and those didnt do anything to help.

    I am getting power out of my ign control mod so i know she is still getting power.

    does anyone have any ideas of what can be going on?????

    Wild guess, ignition switch perhaps. That would feed power to the ECM relay, which powers the fuel pump relay. Also possible you lost a fuse link over on the fender by the relay. See if any of that wiring looks melty. The power feed into the ECM relay comes through one of those. Without the ECM you'll have no fuel and no spark on that one.

      ive went through every fuseable link over there and they are all intact and not melted.

        When you turn the key on, do either of the small relays on the fender come on? Would be worth confirming. If you get power through the ECM relay but it does nothing, possible the ECM crapped out, or maybe the ECM ground failed and is not allowing it to work. My knowing of EEC-III is fairly limited so I don't know where the grounds are or if it has some secondary power feed involved.

                He did not say so, or really anything on that subject. But yes, I'm guessing it's either no spark at all, or not at the tight time. A simple $5 test light that clips in between a plug wire and a distributor tower would confirm the former. I doubt an ignition coil or a distributor are more expensive than an ECM, and both are wear items that sit on the engine and bask in its glow (well, heat) all the time. Three things run an engine: air, fuel, and spark - he got the air as a given, he checked the fuel already, I hope he also checked the spark before going straight for the one part of the system that doesn't really fail all that often unless fucked with...

                  Shutting off while driving feels more like an electrical issue.

                  The ECM is indeed rarely a failure item, but if its not kicking the fuel pump on it could be flunky, or just not getting power itself. Thats why I asked about the small relays, if neither clicks on, the problem is somewhere else.

                    ECA relay could be the issue as well as it drives all the other run/start relays as well.

                      Hopefully it does not have the same problem as my 83 MGM. Mine must have a broken wire somewhere. Sometimes starts. Quits whenever it feels like it.

                        The other thing to check is condition of wiring that goes into the CFI unit and drives the injectors. On the last CFI that I worked on (the Doktor's Mk IV, damn I love that car) years of engine bay heat had shrunk the insulation quite a bit and there was a decent section of bare wire core exposed that appeared they could have been shorting. Unpin the connector, use heat shrink to reseal the wires, repin them into the connector, problem solved for pretty much the rest of the car's life.

                          Does it have that accident fuel switch in the trunk? Might be a place to look as power would have to go through it.

                            Yes it should have that, but I doubt it's his issue. He said that with the relay bypassed the pump runs, the switch is downstream from that so if it was tripped the pump would not get the juice the jumper up front is sending it. Also wouldn't explain why the car still refuses to start even with the pump running in manual mode...

                              Crank sensor perhaps? Through much trolling I have learned indirectly that the computer bits are often not at fault but rather the things that send data to it are more prone to failure.
