    454 BBC Fuel Problem?

    Hi, If anyone is still here, here's where I'm at, I put some gas in the 2nd gas tank, it's a dual tank (I was told the one I just put gas in did not work) and it starts but running like a dog. Can't keep it running. It has a fuel pump right above the gas tank, that's the one I've already...

    454 BBC Fuel Problem?

    Thanks for the input! Great leads! It is a TBI motor. I don't think the location of the exhaust is an issue b/c it was running like a raped ape at full acceleration before and didn't have any issues. I haven't checked the fuel pressure after it dies b/c of my crazy work schedule. I'm on constant...

    454 BBC Fuel Problem?

    Been having some issues with the truck. It was having some issues with stalling when slowing down or stopping, tried everything, fuel pump, filter, full tune up & even distributor itself b/c 2 shops couldn't find the problem. That didn't fix it so I removed the super old fi system and put on...

    Looking for Old School Mechanical Advice!

    My 84 K20 has a 502 BBC, it ran strong then started dying at stops. It got so much worse it doesn't even run now. I changed all tune up componets, even put a brand new distributor on, same thing. I assumed it was the fuel injection so I took it off and put on a Demon 850 carb. STILL, same thing...

    BBC Running terrible

    BBC fires up 1st try, but runs like a dog. Have to feather the pedal to keep it running. NOT drivable! Water/antifreeze is always perfect, never low. Has new distributor, cap, rotor, new plugs, fuel filter, fuel pump, regulator, ect. Demon 850 carb. Blowing white smoke but no oil/antifreeze...

Thanks, we will ck vacuum modulator & do leak down test. Soon as i...

    Silly Question but could I possibly have an ECU?

    We actually bought an aftermarket Fuel Pump but it's suppose to be good to 50psi. My hubbys working 6-12s so I thought I'd join the forum and get some input. He did a little research at work and found info that says a bad coolant temp sensor can make it burn rich, stall, etc Summit has it for...

    Silly Question but could I possibly have an ECU?

    Can't find any numbers anywhere. Thanks for all the help! Like I said, all tune up componets new, fuel pump new, distributor new. Ran awesome full acceleration, then started dying at stops and had to keep feathering pedal to get it moving again but once I got up to about 30mph, ran awesome. Got...

    Silly Question but could I possibly have an ECU?

    It's an early Holley Project 4 system. VERY old analog system. It was on the truck when I got it.

    Silly Question but could I possibly have an ECU?

    Strange question, I know but I have an 84 K20 w/502. Bought truck with an OLD analog Projection 4 fuel injection system. Truck runs amazing at full throttle but stalling when slowing or stopping and hard to get going again. I changed all tune up stuff, fuel pump and even new distributor b/c...
