Question about Cadillac DeVille

1 Answer

I was told the reason my 1981 caddy coupe deville islander is stalling when it gets hot is a problem with the HEI distributor and that i should replace the entire distributor. Is there any specific HEI distributor i should purchase... i know that because my caddy isn't carburated, i need to get one with a 7-digit id number. other than that, could you recommend a website where i could purchase one?

Yes, it's an usual fault on older engines with the HEI distributor .
Yes you should buy the specific one for your engine but all the others can be adapted to fit your with a little work.
If i guessed right this should be it

NO POWER TO THE DISTRIBUTOR ON 87 CADI DEVILLE THERE IS POWER TO CAP


I owned a similar 1986 caddy

12 Volts on pink wire to dist with key on

The top of the cap is the HEI Ignition Coil

Inside dist is the pickup coil (no crank sensor)
& ignition module with the 3 or 4 wires

Maybe the module failed- if you have no spark
at plug wires

I have a 84 camaro with hei distributor motor is a 69 camaro 350 i keep melting the wires on the coil put new coil in car runs good for an hour or so then gets warm and melts wires and stall also did new...


HEI distributor and burning coils,it in you connection first make sure you install primary and secondary prorperly as it comes out of the cap , and inside the cap wire from modules dont make contact if you are burning its from primary circuit, this is the (B+) or (battery most likely), your secondary is your tach and that need to switch from postitive to negative for it to create spark obvously if tach was grounded or applied power you wont start,but there are times the condensor in the distributor does stays fixed and shorts out the coil (replace that condensor its for suppression) when the condensor is replaced run a fused direct wire at B+ (from ignition) run the vehicle and monitor the tach wire and check to see if that get hot

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

Hei distributor on old L6 engiune won't fire coil


'56 engine was likely a "blue flame" engine that had a points type ignition system. If someone installed a HEI setup in there, you need to know what year vehicle it came from. The old system used a hot wire from the ignition switch to the (+) side of an external coil...the (-) lead went to the points. The most common conversion uses the same (+) wire but it then connects to the "batt" terminal on the distributor cap.(coil is inside) There are no other wires involved except for the short harness that goes directly into the distributor that connects the coil, pickup coil and control module to each other..

HEI DISTRIBUTOR PROBLEMS


on the intake manifold you will see 8 numbers, this is your firing order
from the front of the car the left side numbers are 1,3,5,7 and the right side are 2,4,6,8. now ont the distributor cap there should be a number 1 at one of the plug towers. you start there with #1 plug wireand continue.
on a chevy the firing order is 18436572 and this is the order you put the wires on the cap. now the second problem i don't know right off hand which way the rotor turns on your engine. so remove the cap and crank the engine over and see which way the rotor turns, this is the order you put the wires back on the cap. hope this helps
