Well here goes nothing (low dyno)
#121
Yea the tuner is 40 minutes away so it won't be driven at all. The flash tune I'll just be starting it on. The last flash they gave me for when I did my heads and fast I drove it to them and had no issues on it. 2000 rpms will be the max revs give or take this things sees before he has it

OH -- Raise the front as high as you can and still see and reach in the engine bay. Makes burping the cooling system much easier

the good news, it started and had oil pressure somewhere around 60 psi within 3 seconds.......the bad news it doesnt stay running and dies after the same amount of time each time, runs about 3 seconds then its like it loses fuel and revs just go to zero. tried it about 8 times and same result everytime. im goona do some research as im sure i will find my problem without starting another thread, but my fuel pump is lonnies doubles that were already in the tank and untouched this time around. the only fueling thing that has been changed is the ls7 rails and ls7 duetchwork injectors. im still running the ls1 little evaporated thing next to the rail.
im assuming you guys are goona tell me to hook a gauge up to the rail, so we will do that tomorrow

Can you keep it running with light pedal? If so, maybe just crack that idle screw a turn or so

throttle brought more life to it but still died in 3 seconds.....just realized something, the lonnies doubles eliminates the factory venturi, and lonnie recommend not to go below 1/4 one the fuel gauge due to this. if i remember correctly i know it has less than half a tank if not close to 1/3....by me having the the nose about 1.5 feet higher, i bet you its not getting fuel. will try putting it on all fours tomorrow. if it runs for 5 seconds, and wants to stay running, i will kill it, siphon out the fuel, and fill it up with new sunoco 93 and raise the nose again to help with coolant.....sound like a good place to start?

Yes. Get that old fuel out. Fresh 93 is what you want in this car for sure.

Patience is a virtue my friend. This month makes 9 months for me not being street tuned. I did a wot dyno tune in August at Vengeance without a workable wideband. Been abiding my time since then patiently waiting on getting the car tuned correctly. It sucks, but it’s better than hurting something because I got in a hurry. I wish I had more time, but between my business and my sons baseball, there simply isn’t time. Dying to drive this thing properly tuned. I have a LOT more power there, just waiting for my day to come.

all the air is pushed out of the engine, then you can hook the hose up and finish filling Radiator up, works for me every time.

Sounds like removing the steam line from the radiator is good. Since when angled that will be the highest point. I still have heat, any benefits of turning the heat on once the thermostat opens......i would imagine not necessary since I assume it's goona flow the same through the heater core weather the heat is on or not

randomly decided it wants to run......takes work but it will stay running. had my wife holding the throttle at 2000 while i kept slowly pouring coolant into the radiator. ran for about 3-4 minutes. i did notice a little bit of blue exhaust not sure how normal this is........so i have the cap off and decide to check on her, i look in and on the scanner the coolant reads 255 and the coolant needle just began its quick sweep towards the red, i shut it off when the gauge was reading a little over 3/4 on the coolant so i probably caught it in time. after some words with her she was too focused on the oil gauge and keeping the rpms at 2000 and forgot to check the live data gauge. so i give it a few minutes and then put the cap back on thinking ok maybe just pressurize it. i then removed the coolant crossover line from the radiator and i figured would take the advice from the other poster about waiting until you see coolant from there and we are good to go. well we start it up again and there is steam coming from the line, its making gurgling noises, and its spitting out a minimal amount of coolant. i told her to **** it down if the live data says 230. after about 15 seconds she kills and we do this 2 or 3 times and keeps getting to 230. what do i need to do here......brand new ac delco 186 thermostat.

i dont think its circulating because i put one gallon of straight green mixes with any color extended life coolant in it, then was following it with 1 gallon of water. the "coolant" in the radiator is no longer green and is basically clear, meaning its not mixing.

Typically I drill a small hole in the stat flange to get some minimal circulation all the time. You know for sure your pump is good?

If you were at 230, the stat was open...if it’s good. Don’t take anything loose. Button it up and have coolant ready. I buy 50/50 premixed. While running, add coolant as necessary til full. It will bubble and burp several times. DO NOT let it run hot. Shut it down as many times as necessary to keep it at temp. Are your fans operating?

how do i confirm thermostat is open?
how do i confirm the water pump is doing its job?
i assume if its running and operating properly i should be able to squeeze all coolant hoses and feel resistance and heat? including the heater cores correct?
should i go out and start it and try again? should i stop with holding the rpms at 2000 and just let it idle after it reaches temp or continue holding throttle?
