Engine Mechanical problem
2002 Chevy S-10 6 cyl Two Wheel Drive Automatic

The engine turns but does not start. I have 56 to 58psi at shrader valve. I have spark at the plugs. I poured some gas into the butterfly. It back fired out the intake. Also tried starter fluid. It sat for two months. I chargered the battery. Im thinking its the ignition module or the injectors being clogged. No codes are thrown and it has fuel in the tank that I just added today. What do you think?

Hi Fulcrum311, Welcome to 2carpros and TY for the donation

Your fuel pressure should be key on engine off is 60-66psi you're lagging. Open up the upper plenum and investigate the fuel pressure regulator and nut kit. If the passenger side of the plenum is washed up the pressure regualtor is leaking same goes at the nut kit on the driver's side-Get back with some results
