For some reason gas still isn't getting to the pistons. Fuel filter? Vapor locked?
Have the intake air temp. sensor checked .Two wired plug on top of intake manifold. Check fuel pump pressure.
have you replaced and or tested both coils? are you getting no spark on the intake and the exaust sides?
crankshaft-camshaft timing, clogged exhaust, plugged intake, intake manifold leak.
Need more info vehicle getting enough fuel, air or ignition. Fuel pump maybe bad, Air intake system has no leaks, Ignition system working properly. Just need more info
how can transmission fluid git in the intake
The car needs three things, fuel, air, and electrical spark. If it cranks but doesn't start its not getting fuel. Spray some starter fluid into air intake after detaching it from engine. If starts for couple of seconds that is problem. If not check these things, spark plugs fire, and relays near battery.
usually a gastet problem Check the breather tube, you might be getting "blow-by" into the intake.
You can test a car intake system by taking the vehicle to the shop and getting service for the intake system. They would have to put the car on a machine and use their testers.
spray carb cleaner in to intake while starting. if it wants to start, you have a fuel problem.
Try spraying some carb cleaner in the intake while someone cranks it over for you, if it continues to run, you have a fuel delivery problem. Possibly a fuel pump.
sure you have a gas problem ? could be spark problem. fuel pump is run by a fuel pump relay, then it passes thru a fuel filter then on to a fuel rail which the fuel pressure regulator regulates it. simply trick to see if you are really not getting any fuel is take a turkey baster and suck about 2 oz. of fuel into it then spray that into the intake hose to the throttle body if it cranks and runs for a couple of seconds then your right your not getting fuel. If it does not then it maybe spark problem.
If car cranks over and won't start it is not the starter, alternator or battery. Most likely the ignition wires or module, fuel delivery system or air intake meter.
