help needed.

[bryan chrismer]

I switched my 66 fury over to electronic ignition. I followed the directions to the T. now the car runs till it gets hot and stalls out. We have checked the voltage and everything is within spec, but the car still dies. I have replaced the coil, ballast resistor, and the icm and still no change. if you let the car cool down it will fire up but as soon as it warms up it starts to stall out again. What am i missing.

 

[mr. fix it]

it kind of sounds like a defective electronic module, ballast resistor or pick in the distributor

 

[bryan chrismer]

how warm should the ballast resistor get?

 

[Big_John]

I'll bet it's the pickup in the distributor.

Check it by disconnecting the plug at the distributor and check resistance between the two wires going to the distributor. It should be around 800 ohms. 1500 ohms at the most. Anything more and the pickup is bad.

While you have the distributor disconnected, change your meter to AC voltage and spin the engine over. You should have over 1 volt. If it doesn't, and the gap is right, the reluctor is bad.

Make sure you use a non metallic feeler gauge to check the reluctor gap.

ok i did that and its reading 308

i did that the reading is 308 and no ac voltage

If it's not making AC voltage that's your problem.

 

[65sporty]

What brand Dist is it?

 

[Big_John]

Sounds low for the pickup, so I would replace it.... But no AC voltage at all? Is the gap set right? .008-.010" set with a brass feeler gauge.

 

[bryan chrismer]

What brand Dist is it?

proform

 

[CanCritter]

dose it just die or dose it sound like its starving for fuel once it gets hot?...if so ensure fuel lines aren't getting to hot and perculating (boil) the gas...if fuel lines are to close to heat source..fuel will peculate giving you a plugged fuel filter type symptom

 

[Big_John]

I assumed you had a Mopar electronic ignition. I have no idea of the values for a Proform distributor, so don't go by any of the values I wrote.

Proform quality control is reputed to leave a bit to be desired. Go get the Mopar Performance unit. Ignition Conversion Kit w/ Mopar P4120505 Control Unit (Chrysler Dodge Plymouth) | eBay

I know the Proform kit is supposed to be a valid knock-off of the good old Orange, but you're not the first bloke to have major issues with one. Folks sing hosannas of praise for my old style breaker point tuning, and Tilly purrs along better than every EFI car on my block in this barrio.

 

[mr. fix it]

how warm should the ballast resistor get?

they will burn you... it's a big resistor to knock down voltage from 12VDC+ to about 9VDC

 

[FURYGT]

Make sure that you are using a heavy duty ballast resister. If you need a good quality module and your engine is stock or only slightly modified, consider using this module that I have been selling and using for more than a decade:

Chrysler/Mopar 4-Pin Ignition Module/ECU for Replacement Or Conversions

[CanCritter]

putting a proform in the 70...hopefully no issues...seems to be a hit and miss for some folks

 

[65sporty]

I guess I forgot to ask but when it wont start did you check to make sure you are missing spark?

 

[bryan chrismer]

ok got time for an update. went and got a new distributor from orileys checked the gap set it to what you guys said. changed the carb and gasket and it lives again. thank all of you for the help.

It is the pickup deal with it a lot rebuilding them, hey just FYI the rebuilds have any curve in them and they list them to fit say 72-80.
