First have to ask if you are sure that you connected the wires to the new solenoid just like they were on the old one. don't mean to say that you don't know what you are doing, i would be asking myself the same question at this point. if you are certain that you did then try cleaning the battery terminals. take the negative terminal off first, that way you won't generate sparks like you might if you took pos off first. clean up both posts and clamps and wipe the crud off the top of the battery case, use some baking soda on it if there is a lot of oxidation and deposited junk on the battery, it neutralizes the acid residue. if you are not sure that about the integrity of your battery, test it or have it tested. symptoms you describe would be consistent with dead battery. if battery is good and posts and case are clean, then make sure the wires that carry power to the starter and the ground from battery to frame are good. visually inspect both wires, look for frayed spots, breaks in insulation, oxidation at connectors, stuff like that. you can do all this while the battery is disconnected, that's a good time to do it if you are going to take connections loose and clean them up. if all that is good then i have to ask why did you replace the solenoid, and maybe why not the starter too. if the car wasn't starting before you did that maybe whatever was preventing it from starting is still preventing it from starting. hope that helps

Why does my 1987 mercury grandmarquise bog down afer it shifts to a higher gear.

I had a Mercury Grand Marquis that had a similar problem, poor low end performance and bogging down after shifting. I replaced the mass air flo unit and no more problem, also it might help if you clean the throttle bore and related parts , make sure to use the proper cleaning spray to prevent damage to coating inside bore

I am unable to turn the key in the ignition of my 87 Mercury Grand Marquis. The steering wheel is not locked. I think the tumblers are miss aligned. I bought a new Lock cylinder but can't get out the old...

Make sure the gear selector is fully in the park position. If it is not, you will not be able to turn the key to the position that locks the steering. This is by design, so that if someone has to turn the key off because of a runaway engine, they don't inadvertently lock the steering.

Need replacement ignition key for my 1987

A 1987 does not have the theft prevention chip in the key, so yes, you can. In case it is a 1997, you need the chipped key to start the vehicle. This would have to be aquired from the dealer.
