wierd noise/knocking then goes away?
 

hey im new here and you guys have helped me alot in my 89 chevy suburban convertion/to 1st gen 12 valve. I was coming home yesterday pulling my 26 ft toyhauler and after a steep grade it was just getting level and i hear this noise of like a rod knock and i pull over and the truck was ideling real low and black smoke then dies. I wait a minute and restart it and it seemed like it had a hard time turning over and then fires up and is fine?? wtf? exhaust temp never went over 1150 trans was 170 water temp 170 oil presure 45!! everything normal. One other thing thismorning it started then died (cold) restarted it and it was fine. it has never died like that when cold this thing turns over less than a turn and its running? its a new engine hamilton cam ddp inject denny t pin m&h timing advance 60 mm compressor upgrade! any ideas guys?:c:

Sounds like a fueling problem to me, not sure though.

How cold is it at your house, and when's the last time you replaced the fuel filter?

Its only in the 40s! I did the fuel heater delete kit and filter without the sencor last week! a person on this site told me about the delete kit and i did that! One thing i did was just install the delete kit and the new filter i didnt bleed the system! could there be air somewhere? I have driven it prob 175 miles since then!:c:

May not have been a good idea to do the fuel heater delete if you live in a cold weather area.

The fuel heater does nothing except leak. If you look at your motor there is about 5 feet of fuel line after the heater that is full of fuel and is not heated it makes no sense to have a fuel heater

The intake keeps that heated, supposedly, after the engine gets hot. Keeps the fuel stable.

If you replace the o-ring above the fuel heater, it does not leak, most of the time.

Yeah when the engine is warm. the fuel heater is for starting and isnt on all the time

I have never had the fuel heater hooked up! it just leaked and made a mess. I dont live in a cold area!:c:

- The fuel heater is there so as to prevent particles of wax (from cold diesel) from plugging the fuel filter.
- The warm fuel returning from the injection pump and injectors, flows back to the tank and warms the fuel in the pick-up reservoir (in the tank).
