87 Blazer won't start after new fuel pump

I installed a new fuel pump and tank. First try it fired right up. The next day, it would not start at all. Not getting fuel out of injectors, but getting fuel up to the throttle body.

5.7 liter 350

Re: 87 Blazer won't start after new fuel pump

Find a noid light (injector tester light), should be able to get one fairly cheap or make one. Pull injector plug and insert light. Have someone crank the engine while observing the light. If the light flashes then the problem is in the system before the injector (pump, filter , or regulator). If light does not flash it is in the computer side of the system (wirering, computer, solenoids, key switch, etc).
