    Newbie with a problem

    Hello all. I recently joined to learn more about my 03 Marauder. I didn't think I would need help so soon. The story: When my father passed away 12 years ago I inherited his 64 thousand mile Merc. I drove it to my home and parked it in a heated garage. Time flies and now I am ready to drive it. The gas was old so before starting, I removed tank and replaced fuel pump. Gas was slightly yellow but still smelled ok. Used the 10 gallons in lawn mower. New fuel filter and pressure check showed about 60psi. Cranks strong but not a hint of firing. I have some mechanical ability but these Fords are all Greek to me. I am thinking a spark problem or the injectors not getting signal? No codes present. Thank you for any input.

    update: she started on a shot of starting fluid and ran for a few seconds, so it is a fuel problem.

    Does the fuel pump prime (it's audible) when you turn key to "on" but not crank. I would change fuel filter too with 12 year old gas..prolly gummed up inside

    Check the inertia crash reset button to see if it got tripped somehow.

    The inertia switch is in the trunk on the drivers side in case you were not aware. Check that... then fuel pump relay and fuse.

    With sitting that long, could very well be the relay. Tap on it or swap with another like horn or something after confirming it is working.

    Also... anybody think the FPDM? I don't know how often those become an issue.

    Could be, anything is possible especially with electronics. But given it worked when 1st parked, it wouldn't be on my list of 1st things to check.

    Fuel pump can be heard when key is turned on so power is there. I was thinking noid lights on an injector or is there another way to test for power there? I can't believe all 8 injectors are plugged. I have a ford manual which seems useless. I will try to find what fuel pressure is supposed to be.

    Here are the pressure specs. from Chiltons.
    So it looks like your pressure is good.

    I'd say trace the injector harness, make sure a rodent didn't chew into it.

    Sounds like the fuel pump might be bad. (yes, the new one)

    It wouldn't be the first time a new part failed.
