Why would a Ford Mercury Topaz have no spark?

Answer 1

change fuel pump on 1989 topaz. You have two options. Hopefully your tank is on empty or close to empty, with car on jacks, take off the filler hose, support the tank, undo the bolts holding the tank straps, lower the tank, and reach over and unlock the ring holding the pump and gauge. If you have trouble, unplug the wire harness, take off small hoses, then remove the whole tank. Have to turn it a little to clear the exhaust. Now you can see what you are doing. Screwdriver and hammer, unlock the ring, blow the debris away before you take out unit. Replace. Or......remove the back bench seat, cut a hole in the floor where the tank is,(measure from underneath,) large enough for you to work on, and there you go. No trouble this way. Just unlock the ring, clean area, remove old pump and gauge, replace, make sure pick-up filter stays on. Replace o ring seal, put a little lube on the o ring, lock ring, and with a piece of sheet metal, cut to the hole and just pop rivet or small screws and some sealer, and that's it. Don't have to disturb the clamps and lines this way.

Answer 2

Not knowing the year, its hard to say. But if you have a distributor, and have a coil like 1989 1990 or so, and have no spark to the plugs, or coming from the coil to the dist. Then look for the ignition module that is screwed to the lower section of the distributor, have to remove the dist. and mark everything for timing after, need very small socket to remove the module, make sure to use the heat jell, and reinstall. Check timing. Should be ok, providing everything else is good. Good luck

If no spark has been confirmed, then check the Ign. module, coil, & dist.
