no fire or fuel

Okay I have a 98 1500 4x4 360 it'll turn over but not getting fuel to fuel rail and no spark any ideas??

Sounds similar to the ASD (auto shut down) relay going bad.

Find it in your fuse box and swap it with the horn relay and see what happens.

Nope tried that.. this is what happened. I use it for a farm truck took some hay to animals drove it back to shop where I keep it. Share battery with my bronco drove car to shop has different battery so used bad battery and battery charger on jump start tried to start it... wouldn't start tried with bronco battery and wouldn't start just turn over. I switched all the relays under hood to no prevail

And you don't hear the fuel pump attempting to prime the fuel system?

 

[Jason Bennett]

Nope now if I run wire start to battery it'll turn on had my nephew grab coil prong thought I was going to get to laugh but didn't shock him

 

[dodge dude94]

So, the fuel pump will spin up when hard wired?

I'll be honest, I'm as lost as you are at this point, but I'm also not the most knowledgeable.


There will definitely be someone in the morning that can help you further, man.

This could be the very odd one in a lifetime of you fried the pcm or the ckps when using the dead batt and the charger on boost to try and start the truck. I have seen it happen more than once over the years.

Download the FSM and start going through the steps to check the pcm, the ckps, and so on.

Edit: Check the big fuse at the PDB.
