When I turn my keys, no fuel comes out only when I press my gas, and i would had to crank it by holding my key over and constantly push my gas pedal.  When it does I can rev it up but I couldn’t go in drive and press the gas because it would sound like it’s shutting off till I let go and it picks back up and idles fine.  But I had it sitting for a month so I put a new starter with a new battery and it fired right up with no problems.  Then I left to get fuel with no problems and as soon as I got done getting gas i press my gas pedal to leave and it cuts off and does this on what I just told you..

The engine light comes on only when key is turned on not cranked tho. When it is cranked engine light goes off.

Also injectors don’t get as much gas as it should. Only sprays a little when pressing gas pedal. I got a new fuel pump and new fuel relay. I can’t press my gas pedal no more in park to rev it because it sounds and feels like it shutting off. White smoke from exhaust just a little tho. Barely visible and strong gas fumes inside and outside truck. Now when I try spraying starter fluid it still won’t crank just turn over and sound like it’s trying to a little. It’s a rebuilt motor just been sitting for a little over winter.
