i had this problem with my truck, turned out the fuel pump was bad and as soon it was under load it died, problem went away with the new pump, maybe its something you could try.

A little more info>> Year and engine.

Fuel pump could be the problem but can you run the vehicle at all? In other words does it die as soon as you put it in gear?

What's your RPM at idle in park?

thanks for your responce engine is a 283 1966 i beleave tran is a77 turbo from a chevelle engine was rebuilt but not by me carb was rebuilt by the guy i got the engine from but he did not rebuild the engine. i ran the engine in but never tried it in gear untill i felt comfortable the engine was ok. when i tried to put it in gear it stalled,a friend and i tuned it timed it with no change,so i have changed the rotor,the cap,fuel pump, checked for vacuum leaks with no change . engine will idle ok ( no tack ) i guess around 1200 rpm but stalls when put in gear at idle , if i rev the engine it will move but dies as the rpm drops. please any more suggestions would be a help thanks much RV

I've had torque converter/transmission do the same thing before. Assuming that not the problem, you need to check a few other things first.

Do you have the original points distributor or HEI?

First check the vacuum advance to make sure it's working properly.

If it's HEI, check the timing again and insure it's set at app. 10-12 degrees BTDC at idle. Then increase the rpms and check that the total advance is about 30-35 give or take and see if that helps.

If it's non HEI then do the same thing but use the actual spec setting for initial timing. Don't forget to plug the line from the carb to vacuum advance.

sounds like the torque Converter is not releasing at idle

I agree! Put the rear of the truck on jack stands and start it. If it idles and the wheels turn, you've found your problem. If it's a lock up convertor, it's may just be a bad torque convertor solenoid in the transmission.

well i tried what you suggested. jacked it up started it let it warm up put it in gear ran just fine when i put on the brakes it stalled did this severl times same thing . so i would guess its the torque convertor. some facts the trany is out of a 77 chevelle inline 6 , pulled trany drained & changed filter,trany had only 40 k on it,reassembled it with the right fly wheel and mounted to my 283, is there any easy out of this or do i have to pull the trany ,i have limited equpt. and am working on a gravel floor. hope by the beginning of next week it will be over 40 degrees up here. thanks much for the help RV

sorry i'm still learning how to navigate this site . iguess its the torque conv. it runs in gear with the wheels in the air ,but stalls when i apply the brake.i guess there is no easy way out of this .if i must drop the trany thinking of putting a 3 or 4 sp. back in , any thoughts on this.thanks for your help.RV

I seriously doubt its a torque converter issue. Unless its a lockup torque converter its not possible for it to stall the engine.

jack the idle up a little a and see what happens when u put it into gear but do it on an open street if it just take off it's the torque converter !!
