I am sorry your having this problem
can you check and see if the fuse called WS WIPER a 25 amp fuse in the drivers inside fuse box shows for volts at it with the key ON ?
with the key ON does that fuse show 12 volts at it testing it with the fuse in place through the little openings in the tops of that fuse ?
and can you also be sure the big 50 amp fuse called IGNB shows 12 volts on both sides of it testing it in place through the openings in the tops of that fuse in the under hood fuse box ?
ok if the BIG 50 amp fuse shows 12 volts on both sides of it and the wiper fuse in the inside fuse box does NOT show 12 volts when the key is ON then we need to get to the ignition switch and see if BOTH big red wires show 12 volts at them at the ignition switch next
when the speedo and tach are not working with the truck on what does the fuse called IGN1 in the drivers side fuse box show for volts ?
when it will not crank over the engine does the fuse called CRANK in the drivers side fuse box show 12 volts at it when the key is held to crank and the engine is NOT cranking over ?
can you also check the ground connection at the back passenger side of the intake manifold is clean and tight ?
these usually end up being bad ignition switches or the wiring to the back of the inside fuse box or at this point possibly the gauge cluster itself doing this
going to be very hard to nail down when we cant test it when its acting up
and this is a brand new electrical ignition switch you installed ? not the ignition lock cylinder ?
with it not cranking can you see if the big red and the big orange wires at the ignition switch show 12 volts at them
this was replaced here ?
no at the ignition switch itself
i was just making sure the complete ignition switch was changed with the 1/2 picture i sent to be 100 % sure
you can check it the fire wall and also
i am out of ideas lets see if another expert has any ideas
hang on another expert will replay back to you
Hi there, I am Cam. I read through and see a lot of things happening. What we need to do is pick one issue that happening and follow that. Can you tell me at this moment what the only issue is remaining?
Ok, I realize some of this is repeating what you and Gary talked about but I think a fresh approach is needed.So when you turn the key, do you hear a click from the engine or the fuse block? Is there a remote starter installed? Does putting the shifter in neutral make it work?
Good place to drive on a sunday!!. So then I realize it will take time. WE need to see what it does in neutral when it does not start.
OK, but the signalling sent to the starter relay through the neutral safety switch is what I am curious about. And confirming you have the old style 1999 with the 350 vortex not the newer 5.3L system.
Ok, perfect, you listed a classic which can means old. So lets see what happens tomorrow, In the meantime I suggest you check some ground wires.-under the drivers door on the frame, take those grounds off, clean them to bare metal and put them together.- Firewall to engine braided ground strap-engine to battery ground.
Ok, Let see what that does tomorrow when it acts up and connect from there.
Ok, Have you tried swapping out the starter relay yet?
yes it is.
Ok. Sounds good.
The message centre may be dead, it is common. AS for the fuse, what is the Label?
Is that fuse dead now then?
Ok, try this. On the data plug, top Center of the plug there are two pins together. Use a wire to jump those 2 together and see if that makes it work.
There are 3, the cruise fuse, Ign 0 and Ign 1 fuses are all the main fuses in for power and the radio fuse is the main battery power input.
