It gets spark so I'm assuming the asd is sending power to coil.
I put a multi meter to the crank sensor to the middle wire,with key on and didn't get a reading also

If you are getting spark, then the ASD relay is doing its job.

What happens if you put a jumper in place of the fuel pump relay?

If you look on the bottom of the relay, the terminals are numbered. In the socket the relay plugs into, stick a short piece of wire into pin 30, and the other end into pin 87. The fuel pump should run.

And I take it if the fuel pump does send fuel the relay is bad?

If the pump runs with the jumper wire, then either the relay is bad, or the PCM does not want to engage it, for whatever reason...... Test and see if the pump runs, take it from there.

Can I try and start the truck using the jumper? I work night shift and will be doing this at 4am so won't have a helper listening for pump to prime.
