man I'm lost. I had a wire from my off road lights arc out behind the dash and now my truck wont start, well it turns over but has no spark.

I have swaped out the coil/ignighter, main computer, magnetic pickup inside distributer, and the fuse and relay are good.

the EFI fuse was blown but no its good since I replaced it.

 

damn I just got my 5:29 gears put in and on the test drive this happens, I need some help so I can go out wheeling

 

with key-on, do you have 12v on pin 3 (Black-Red) of the ignitor? Pin 1 (also Black-red) of the ignition coil?

 

hold on I'll go look

 

yes on the ignighter I do have 12v

 

its a black and white wire going to my coil. its one of the weird shaped ones from 93-94

 

Have you seen any burnt or melted wires under the dash from your arcing wires??

All these parts you replaced were new ??

it is possible one of them was bad out of the box.

Known good used parts tend to corrode at times unless the plugs are coated with dielectric grease

 

no burnt or melted wires. and I didnt replace the parts I just swapedthem from a good running truck

 

Check all fuses...possibly remove any unnecessary accessories (fog lights for one). Pull each fuse and inspect. If you have an ohm meter, check for a fuse having higher resistance.

What circuit were your lights attached to?

 

thats the thing I had them redneck wired, 1wire from the + side of battery to my toggle switch and then 1 wire from lights to the toggle switch. and when it arc the positive side connecter touched a part of the metal dash

 

I have no idea, I have checked everything in the ignition circuit

 

Is there anything else not working??

Just what did your wire arc against ??

Because other then the ECU/ECM the EFI Fuse and EFI relay have nothing to do with the ignition.

Now if you said you were not getting fuel that would be different.

A dead short to ground just goes back to the battery.

Why you had no protection is the circuit is your business your lucky the truck didn`t burn.

 

it arc against the metal dash part by the hood latch/on the lower driver side

 

yea as far as I know its just spark, I have a blue-point checker and yea no spark. the engine turns over reallly fast thus the no spark

 

I figured it out. the timing chain that I just had installed broke. not even a few miles out of it. just a weird coincidence of the arc the same time the chain gave out. So yea I have to do the timing chain job all over again! ahh damn Cheap parts stay away from ebay junk.

 

here is the new one that broke

 

I am glad you figured it out.

Just one of those freak things that was unrelated to the sparks.

your lucky the chain did not jam on the crank sprocket .

 

That is crazy... Specially being that it occured right after the spark... That would definately not have been my first place to look. Glad to see you figured it out. I had an issue with mine not starting and it was due to a wire from the main harness infront of the Intake manifold and was not able to figure it out until I took the thing apart.
