Put stage 2 cams on it it will go faster and it will run fine if it's flooding.lol But for real it can be your ING relay or fuse. It might be bad valve or valves. But most likely I would say is the fuel pump. There is certain pressure it has to put out if it's less or more it won't run. And some cars even if it's 3 or 5 psi over or less it won't run right or at all

Gas pump check the fuel pressure. Rent a tester at O'reilly for free.

Check your Engine temprature sensor for the computer. If that circuit or sensor is open the computer thinks -40 degrees and drops fuel for -40 The sensor will be on the front of the engine around the thermostat housing (where the upper radiator hose is connected). The sensor will have a yellow wire (signal) and a black wire (ground) connected to it.. You can try bridging the two terminals in the connector and seeing if it starts then. This will tell the computer 240 degrees temp so if its cold it may not start from not enough fuel. My experiance has been most failures are not to much fuel pressure but injector control issues. Coolant sensor is fairly cheep and you can plug it in without installing it before you install it as it will be close to engine temp and accurate for a while when first started.
