(SOLVED) truck still wont run

[4doorciv]

Wow. It looks like you found your problem. The reason why it burned, and possibility of it burning again after repair is the question. I'm supprised it melted because the fusable link should have burned first.

[joey_crandall]

yeah im kinda at a loss now as of what to do. or what to test.

[joey_crandall]

also yesterday i checked to see if the dizzy was in correctly and the crank pulley wasnt tightened down all the way. i could move it with a socket without a ratchet. idont know if that could cause anything, figured i should mention it.

[4doorciv]

The crank pulley as in the 4 bolts that hold it in or the big bolt with the 1/2" ratchet hole in it? Well, you chould check to see if there is power going to it, what where there is also power. With the plugs melted like that, you should track further upstream and downstream of what else is burnt. I can already see that you can either replace the ignition or attempt at fixing it by replacing the terminals. If it's melted elsewhere also, there would be no change after the repair.

[joey_crandall]

ok i see what your saying. and yes it was the 22mm crank bolt that was loose. so with the ign stuff, think i should cut the looming off and look for burnt wires.

[4doorciv]

Well, the crank pulley should be installed with the 4 10mm or 12mm bolts. Not really the 22mm bolt. But yes, look for burnt wires. The burnt wires would turn into a short to power or a short to ground. And it seems that you have a short to power with the key in the off position. After the key is in the on position no power so open circuit.

[l.k.]

atleast you found out something man, keep it up. I would def. track wires searching for burnt ones/ melted etc..

[joey_crandall]

so earlier i was untaoing the harness under the dash and i heard things clicking under the hood. also i found a couple hacked together wires. im not sure if its factory, but i think the factory would have soldered the wires and shrink wrapped it. instead of a wire crimp and electrical tape. ill get some pics later.

[4doorciv]

Clicking? As in relays clicking? What wires do you think they are connected to? Ignition? Ac? Fuse box?

[4doorciv]

Did the car have an aftermarket alarm on it before? I seen some shops work with alarm installs and it's usually messy and unprofessional. Most of the time screws go missing and things get damaged. Small stuff like scratches and broken tabs.

[joey_crandall]

i have no idea what they went to it could have been the ecu relay, im not 100% sure. and it didnt have an alarm when i got it. in some places there multiple wires that stripped and tapped to a single wire in the back of the cabs fuse box.

[joey_crandall]

the Y made from the two black wires are hooked directly to the fuse box by one wire.

If it was a clean job then it should be stock. You can always make a trip to u strip it and take plugs or a wiring harness. If taking a harness then try to do a clean strip job.
Bit it looks and sounds like you are on the right path. Now that you have herd clicking from under the hood. If you can make it do that on a regular bases then you can find out what is clicking. Keep it up your getting close.

[joey_crandall]

it could have been the ecu relay in the cab clicking. i was kinda disoriented under the dash. but i think its getting there to. i sure hope so anyway.

[4doorciv]

To me the splices look oem. They did that on my eclipse harness the same way and electric taped it. Try to see if you can isolate the clicking to a specific relay. Did you try searching the oposite end of the burnt wire harness as well? It could be closer to the ignition then further then that into the cab.

Make sure to tape up the exposed wires.

[joey_crandall]

im getting the wring diagram of the net, i lost the other one i had.

[l.k.]

way to keep on trucking man...i feel you will have this thing whooped soon enough. Goodluck bro..

[4doorciv]

Happy hunting man. I don't think this would be a dealer item anymore because out trucks are obsolete. You are going to have to find a donor truck from the local scrap yard. Unless there is a cross reference to another vehicle that isnt obsolete.

[joey_crandall]

thanks man, i couldnt get the diagram on my home computer. so itll have to wait till tomorrow. but im gonna test each enf othe wires that come from the igns witch.

[joey_crandall]

its starting to seem like i have a bad ground. i put the ecu back in yesterday. and i left the key on, but as the ecu case tapped up against the ecu mount the speakers made funny sounds. like when your cell phone rings when your listening to the radio.

[4doorciv]

Seems like it. Try to disconnect the ignition key and perform the same test. It could be a sdhort to ground, or short to power still.

[joey_crandall]

so im not getting anywhere, its probably gonna go to the shop my brother works at so he can look at it. the have better tools and testing equipment.

[4doorciv]

I'm sorry to hear that. Good luck with the truck. Hope it gets fixed.

[joey_crandall]

yeah me to. at least itll get done for super cheap. my brother can work on it when hes not busy at work, that happens quite often.

[l.k.]

man what luck....atleast it seems to be a simple problem --just hard to find. GL with getting it fixed man....
