Picked up this truck for cheap 300 inline 6, manual transmission, 4x4 dual tanks. So far it has a new starter as the old was dragging, has a fresh tune up, wires, plugs, cap and rotor. New PCM, new EEC Relay, new fuel pump relay. Battery tested good and fully charged. All fluids are topped off. I can hear the fuel pump priming and am also getting a strong 55 psi to the rail. Compression tested good in all cylinders, and I am getting spark to all 6 plugs and the coil. Guy I got it from said he recently replaced the distributor so I'm thinking it could be out of time. Air intake is free from obstructions and filter is new. Truck will not start with starting fluid or gas, and the rotor does turn however slowly when I crank it. I am utterly lost at this point.

Only thing I have noticed is it doesn't even wanna start just cranks and it seems to crank faster than normal. What do I do next?

Also had a new coil

 

If the engine hasn't started since the previous owner replaced the distributor it could well be out of time. You can check the timing with a timing light without the engine starting by hooking up a timing light in the normal manner and cranking the engine with the starter.

NOTE: It's possible that the distributor could be 180 degrees off and still show perfect timing using this method, just thought I would mention that.

 

And a good NOTE it is ...

And just to add a bit, if you want to ensure it's not 180* out, pull the #1 spark plug, hook it back up to the spark plug wire, ground the spark plug good (or use one of them clamp on spark check plugs), hook the timing light back up, crank the motor again while watching the timing marks, if it's blowing air out #1 as it passes the mark you'll know it's not 180* out!

-Enjoy
