No Compression?

Asked by punknnpretty22 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?

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
