Help needed, starts but wont run
Help needed, starts but wont run Ok, so I have built a turbo transam, DIY truck manifold kit, tc78, proflo intake, nice 317 heads, full fuel system. The day I finished it, my friend and I started it up, car fired right over, idled smoothly, for the cam thats in it, had good throttle response, everything great. Had a small fuel leak, shut the car off, repaired the problem, started it again, ran REALLY rough, but didnt die, rev'd it a little, and still when it came down didnt die. Shut if off again(another fuel leak). NOW all it does is start, and shut off, maybe 3-5 seconds run time....WTF!!!!!!!!!! If I try to give the car throttle while starting it, it kills it quicker, doesnt loose fuel pressure, shows 9-11 in. of vacuum when it fires, dies off when the car dies... Going crazy, has fuel, has spark, has a tune for the fuel system and turbo in it....I DONT GET IT, what the hell happened??? Im really gettin fed up...dont know what to do anymore guys... any help would be appreciated. Thanks, Dennis

are youy sure have plenty of fuel pressure have you tried starting it on ether or brake clean and seeing if you can keep ikt runni ng that way. Remember that pressure doesn't equal volume too a restriction may show pressure but not supply enough volume to sustain the engine
I do not have access to a scanner to read the map....sorry, however the map does seem like its reading, we tried unplugging it, and it just fires and doesnt even try to catch itself...plug it back in, it tries, but cant succeed....Im goin with a vacuum leak, gonna pull the intake off again....
