Ok 1983 camaro...305 4bbl....stock HEI ignition


car cranks wont start

verified fuel delivery

held spark plug wire near header...cranked...no spark

replaced....ignition module...ignition rotor and ignition coil

ive checked all wires......and all connections..all are in good shape...

battery and alt are good....

simple system..yet im stumped

any hellp is greatly appreciated

 

Still no spark? Did you replace the module with an AC Delco? A lot of the aftermarket crap is bad right out of the box.

 

yep acdelco..im stumped 2

 

ttt...anone got any clue

 

Have you verified you have 12 V going TO the distributor?

 

Try disconnecting the EST connector in case the EST is killing the spark primary.

 

est connector...that would be...what...and no didnt verify voltage to distributor..btu battery is brand new..what would i have to check...im not totally new but not experienced as some of you guys..so any help would be appreciated no matter how basic

 

EST wire is the lone brown wire coming out of the loom on the firewall on the passenger side, it has a single pin connector on it. Disconnect it there to eliminate the EST.
To check voltage going to the dist, find the connector on the cap that is labeled "Batt", that is the 12 V input to the dist., check it for voltage to ground with the key on.

 

i just checked..dont see brown wire....or single connector on passenger side..what does est stand for...still have to check voltage but its 325 am so ill wait till morn..lol

 

EST= Electronic spark timing (what the ECM uses to adjust timing)

But by the looks of that pic (if thats you & your car) then i doubt you have the computer controls any more...So, verify 12 V going TO the dist. If it has 12 V going in then it has to be one of the parts you already changed that was bad from the box.

One more thing, check the grounds from the engine to body, make sure they are there still and clean (under the connecting lugs too)

 

...And on an '83 or other CCC car, the EST connector is a four-wire, flat connector at the distributor.

 

yeah as you can see from the pic no computer controls...or computers for that matter...lol...i tried to keep it simple...im bettin it was just a bad part out of the box..cause their literally isnt much else to change..but i do need to verify voltage....

ill keep ya updated

 

simple is the way i like it and in my eyes, if theres a computer running the shot, then simple is far from reach lol...

if you find your 12 volt power is in fact dishing 12 volts, i would focus your attention back to your coil... the ignition module can be tested but have them test it a few times (to get it heated up) or use a blow dryer... but i think its your new coil =]

 

so you think that i may have replaced the bad coil with a bad coil...great...lol

 

Kinda hard to say. Have you checked out the rest of the dist? Reluctor ring, magnets, primary coil and all the connections inside the dist?

 

ok youve officially surpassed my level of expertise..i have a manual though so i will look into how do do that

 

Heh, ok. While you're at it, there is an Ohms check you can do on the ignition coil to see if maybe it is defective.

 

just an observation......Did you put the grease on the module???? If not, it will short out instantly and be dead like the old one.
