The fuel pump is pumping, checked pressure shows 35-40 without cranking, checked fire, all plugs and coil are firing, turns over and tries to start then spits a mist out of throttle body, tried spraying starting fluid directly into throttle body but does not make a difference, acts like it is not getting fuel, changed the plugs, changed oil pressure sensor (since this can cause the ecm to turn off injectors), checked codes with scanner shows only 12 which is all systems ok. I need help before I put a bullet in it.....please............
Which engine? Check firing order (maybe distributor is off, or wrong plug wire to cap or spark plug). It's either spark, fuel or compression. So if firing order and distributor initial and advance timing are set right, and pouring gas down throttle body doesn't work, check compression (worn rings, sticking valves) and valve timing (timing chain might have too much slack or chain jumped a tooth. Replace timing chain if it's worn). If pouring gas down throttle body works test injectors ( MPFI or TPI ) with noid light or have parts store clean and flow test them (around $7-$10 each). TBI injectors are easier to tell if fuel is spraying ( you just need a bright shop light or flash light, and a helper to try to start engine while you look for a strong conical spray pattern). If you don't want to remove everything to check the timing chain, at least try pulling the valve covers and turn the engine over with a wrench (Twist back and forth and check to see how far you have to rotate crank before you notice the rockers moving up and down, also make a couple of complete revolutions and look for rockers that aren't moving much in case of worn cam and or lifters).
I believe i would check my module or rotor it may not be getting enough fire.to the moter.

V6 3.1, Engine was running perfect and just quit while driving, will only hit a lick once in a while and spits fuel vapor out throttle body. Tested ignition module, maybe pickup coil? Maybe fuel pump works but is not up to spec, tested at 35lbs but when you push pressure relief valve it just dribbles out. Somebody please help, this is my daughters car and I have to get it fixed so she will get off my couch!
cranks but wont start
