I have and 89 runner 3.0l. I bought it cheap because of a no start condition. Towed it home and found timing off. I reset the cams and crank and it started until the belt jumped again. I replaced the belt and restabbed the dist. Also replaced valve cover gaskets dut to a leak. After all this it will not start. I have checked and I have spark at the plugs, fuel at the rail, timing is correct, and good compression on all cylinders and still no start? Any ideas? Thanks
