Wont start push starts fine. sputters when step on the gas.

87 will still burn --- check fuel pressure and fuel pump operation --possible bad gas --clogging filter or possible fuel pump failing

Did you try holding the gas pedal to the floor when starting ? It's getting too much fuel or not enough . Hooking up a scanner that can view sensor data parameters should be done to see which sensor is out of range . Coolant temp sensor possibly .

Sounds like you might have clasped the rings and you have no conpestion do a conpestion test on it

Possible low fuel pressure. Should be 31-35 depending on which engine you have. Check to see what you have.

Sounds like a vacuum leak.

It is odd that there are no codes registered. Have the scanner connected while you simulate the condition and get the check engine light.

Since we do not have codes handy I would suspect, bad wiring. Have the fuel pressure tested. The problem may be from the lack of fuel being supplied even if the throttle is stepped on. Check the sparks from all of the plugs. When you check the sparks from the hi-tension wire, do it one at a time to check which causes the sputter.

Other than that it could be loose wiring or vacuum lines. If you have carb cleaner handy or throttle spray, try spraying the intake of the car. At times it may help.

take a look at the fuel pump

I am having the same exact issue right now with my 01 Alero. Been having electrical issues with lights coming on and off. ABS was kicking on a few times even. It started sputtering like it was running out of gas, thought that might have been the case. But after I put gas in it it still didn't start. Now it turns over but nothing. What ended up being wrong with yours?

start with a full tune up plugs wires fuel filter air filter ect.

sounds like the same problem i was just having try changing out your fuel regulator its pretty pricey try to find the cheapest around $75.
