TOYOTA LANDCRUISER

Hello all, hope you can help me out. I am working on a 93 Toyota Landcruiser with a 4.5 liter straight 6 in it. I pulled the head and had a valve job done and replaced the timing chain. All timing marks are lined up properly and the truck started up yesturday after some turning of the distributor. I drove it around and the truck ran fine except a little rough on the bottom end. I made several stops and it started up easily. This morning I woke up and it wont start at all. I get a couple of sputters and thats about all. Anything I should look at would greatly help me out. Thanks

Put the engine on TDC, remove distributor cap-look where the rotor is pointing at-it should be pointing directly at the no.1 sparkplug tower.-If not you have to reset by lifting the dist. And get the rotor to point at the no.1 tower then tighten the holddown bolt.

You sure you don't have it on exhaust stroke?When put back together?

I had everything apart and checked the timing 2 different times. The balancer is at the 0 degree mark and the 2 shinny links on the timing chain are where they are suppossed to be. (Top timing mark on the cam shaft sprocket and keyway on the bottom of the crank sprocket) the 2 dots on the cams gear face the head/valve cover and the single dots on the cams gear align with each other. That is the way the book said to do it. I then put the distributor in and set it to fire on the #1 cylinder. Only after playing with that setting it would run. Now that it warmed up a little it started today. It was real rough running at first and then cleared up and is running good again. With the engine running it seems to be timed at about 13 degrees before TDC which is about where it should be according to the book. Anything else I should look at?

Type of fuel system-Any vacuum leaks-try retorquing everything-especially the I/Manifold.

Check all connections on your ignition system.

When it refuses to start check for spark and fuel.
