check the oil sending unit at the back of the intake manifold and check the oil filter and oil cooler lines one of them might be broken and the oil being pumped out
Go back to basics, spark and gas getting to the cylinders? Does the engine crank at normal speed for cranking? If so, check spark and gas. If it's in time, it must have lost one or the other.
One easy way to check, spray some stating fluid into the air intake (take off the large boot) and try to start. If it runs or almost starts on the fluid, you know it's a gas problem. If it doesn't fire at all with the fluid, it must not be getting spark. Then you check out or test the ignition system.
Did you change the fuel filter also? Look at the air filter. If you have throttle injection, make sure both injectors are working. Might want to clean throttle also. Check for codes? Idle air control motor stuck could cause this. Tune up maybe. I would check compression of the cylinders before putting any more money in it.
Could be the computer not good PCM also just because the ignition module has been replace it could be defective I had new parts good bad you can go crazy trying to fig it out then it might be a new defective part or module igintion good luck
Im suspecting a problem in the fuel pickup tube in the tank. Possible rusted and when you have the fuel run to the back of the tank the hole is exposed allowing the pump to pump air and you are in effect running out of fuel pressure.. Suggest you consider pulling the pickup unit and check .
First, you have to bleed the master cylinder on the bench before you install it, or else it will have air it that will be very difficult to purge. Almost all rebuilt M/Cs have an instruction page inside the box that goes about explaining the bench bleed procedure. You make lines that feed from the outlets back into the reservoir and work the piston until all air is purged from the M/C. Then, after installing the M/C, you can bleed the individual brake lines in the normal manner. See this youtube video for assistance...

Sounds as if the injectors are not operating. Check all fuses. Does check engine light come on for a bulb check prior to vehicle being started? If not, suspect ECM fuse/s or bad ECM
