first would not even turn over. cleaned all terminals on fuse block and replaced fusible link from battery. Truck now turns over, but I cannot hear the fuel pump prime or run. started chasing power with test light and found that starter was grounding out. Fixed that issue. Will turn over but still won't start. Checked all fuses in fuse box... all are getting power except for the crank fuse which is the power for crankshaft position sensor. Correct?? To my knowledge this will keep the engine from starting by not allowing the fuel pump to run. Pretty sure. Now I'm not sure what to do next without chasing a bunch of wires to see what has power. Any help or direction would be greatly appreciated. Thank you.

Hi,

It would make sense that the crank fuse would have something to do with the crank, but it doesn't. Take a look at pic 1 below for what it is for. That is the under-hood fuse box.

I'm surprised you have it cranking without that fuse working. It is for the clutch pedal position sensor to engage the starter.

Now, since you have it cranking, I want you to try something. See if the engine starts if you use starting fluid. If it does and then stalls, we will have confirmed it is a fuel issue. If there is absolutely no change, I need you to check for spark at the plugs.

Here is a link that explains how that is done:

Try this and let me know the results.
