No Compression?

Asked by Nov 16, 2010 at 09:27 PM about the 1984 Ford F-150

Question type: Maintenance & Repair

I had a valve cover oil leak because my old ones were bent. I replaced them after letting the truck sit for a month or so. The truck started up before it sat for a month or so, and I replaced the valve covers and fixed the oil leak and now the truck won't start. I replaced my ignition coil and when I try to crank my truck, it acts like it wants to turn over & sometimes "back-fires" and blows a blackish smoke out of my mufflers. I don't think I have any compression, what could be wrong? What could I possibly do to fix this & make the truck start-up again?

under the dis cap you will see a black box with 2 small screws in each end,cant think of part name.remove it unplug replace with new one,take old one with you to parts store.

sounds like your rotor for your distributor is in the wrong spot. causing your truck to fire in the wrong sequence. remove distributor cap and set rotor to before #1

NO way rotor can be wrong it screws in only will go on one way.
