94 won't start cold

[thenn3025]

Did a search ,but couldn't find any like mine. Short or long story about it.1994 5.7L TBI. Had a cracked head a couple weeks ago, so tore down and fixed that. After that when you cracked the throttle it would want to die. Then it went to a no start mode. Pulled it to my local mechanic as I could not figure it out. Had spark. They found plugs were fouled bad. With new plugs it would fire. They then found that the injectors were dropping massive amounts of fuel. The temp sensor on top was bad and the ECM was also bad. Replaced both. ECM was from salvage yard. First one wasn't the right one, as when I went to drive it home it would not shift out of first gear. Got the right one shifted fine and ran fine. My problem now is it will not start with out squirting a little fuel down it. Mechanic couldn't figure it out. He was using ether figuring it was more volitile and that the spark was weak. So I tried gas and it does the same thing. It runs great after it starts and it starts when it gets warm. This is what has been changed. New fuel pump, filter, plugs, wires, dist cap, rotor, ignition module, tried a different coil. Only thing left is injectors. It doesn't seem to be getting fuel at start up. Help.
