my car was running fine then shut off without warning now it wont start, i shot it with starter fluid and nothing, everything is brand new, any help would be awesome, thanks

How does your coil look. Fill me in with whats new with your ignition set up

theNMBR27

What about your ignition control module under the distributor cap ? Sudden no spark issues usually come from that

kimberanton

entire spark system is brand new

kimberanton

GM said i might have snapped my timing chain

kimberanton

i do have another ICM though

theNMBR27

Does the engine turn over? If it does the timing chain is probably fine and its very unlikely that you'd just break the chain. Make sure all your grounds are good on the back of the cylinder heads and that nothing else is unplugged.

kimberanton

it turns over and all grounds are fine, just checked them

kimberanton

it was running then tink, then it just shut down

theNMBR27

You must have a wire off somewhere. Any after market ignition parts or all stock

kimberanton

all stock, just checked the wires again, everything is hooked up

kimberanton

i replaced them all to stock specs

theNMBR27

Can you take the module out of the cap and have it tested. Advance auto/ autozone and oreillys can all test it. Don't let them tell you other wise.

Same thing happened to my 85 and was a bad ICM so give that a shot

kimberanton

i have a good ICM, ima go replace it real quick

bigbubba1488

kimberanton

replaced it and no change im out of ideas

bigbubba1488

pull a plug a touch it to the header while you crank it to verify no spark and lets go from there

bigbubba1488

Also take a pic of you distrib. for me I wanna see if you have a top mount coil and if you do take the cap and and see if something may have fried

kimberanton

no spark

kimberanton

checked it all when replacing the ICM, everything is fine, it only has 4000 on it

kimberanton

coil is off to the side

Start with the basics check for power koeo on the coil grey connector pink wire and trouble shoot from there. Im not sure how many kv your spark tester is or adjustable gap but use a 40kv tester. Not to second guess you but have you done a compression test or actually check for spark or are you just throwing parts at the car?

kimberanton

which one do i check, theres 4

bigbubba1488

So if your coil is getting juice then your problem is going to be somewhere within the cap and rotor because it's not connecting to send the spark to the wires just make sure before you start ripping into that the wire is securely connected from the coil to the cap

kimberanton

i also have another coil

kimberanton

does the key need to be in the on position, then check the pink wire?

bigbubba1488

Do you have all of the old parts from your tune up?? If you do the easiest way to check it, is to slowly start putting them back on until the car starts. That's how I would do it it should only take about an hour or so but start from the simplest things first

bigbubba1488

If you want to check for power I would think so, It wouldnt be a constant

yes as stated above key on engine off

kimberanton

check the power to what? the coil

Tuned Performance

iTrader: (92)

as stated in post #23 yes the power to the coil

kimberanton

pink wire has 11.88 volts

kimberanton

coil has power and wire didnt so its between coil cap and dist

kimberanton

ill replace the coil reel quick

your battery surface voltage is a little low , you can check the primary and secondary resistance of the ign coil. Im not sure why you are unwilling to test anything but if you insisted on being a parts replacer not a mechanic good luck with your repairs.

kimberanton

went side to charge the battery and all relays and other thing started clicking and humming

kimberanton

i have all parts i took off

kimberanton

ive went through the entire wire harness 4 times, all wires are fixed and pluged in

kimberanton

i have DMM but i dont how to use it all that well, my mechanic is on vacation

kimberanton

im just going to sell it or buy a new wire harness, 2000 as is
