Re: 93 Cavalier spraying lots of fuel.
What exactly is happening if you have a spark plug out of a cylinder you will get fuel out of it? is fuel leaking? are O-rings replaced and use silicone to lube them NOT OIL! oil destroys rubber O-rings.
even if there are wire problems you should not get fuel leaking anywhere. fix your fuel leak first. this can cause a vacuum problem and GMs dont like vacuum leaks.

I would start with checking the fuel pressure and boosting the fuel with spraying carb cleaner into the air intake hose. It sounds like you are not getting enough gas into the cylinders. Could be a vac leak too.
Pull out # 1 spark plug and put back into plug wire, rest on motor block so that end of electrode is against metal. turn motor over and have a finger or compression gauge in # 1 cylinder, check to see if spark occur at same time as compression (compression will blow air past finger or raise gauge). When you say it has fuel do you mean gas tank has fuel? Are you sure fuel is getting to the cylinders? are plugs wet with fuel? Does it turn over but kinda thumps or backfire (Caugh)? Check the spark and compression first. if they don't happen at same time, the timing skipped or belt broke. if all is good pull plugs and inspect, could be flooded (WET) from fuel. either replace or spray with starting fluid and compressed air to dry them. spray starting fluid into air intake if starts then stalls, try again, if same thing happens then you have a fuel problem. try these suggestions first 1/2 hr time table, hopefully sucess, if not it sure indicates fuel.
you need to check see if it is getting fuel sounds like a clogged fuel filter and when you pump the fuel peddle you are puttting it clear flood mood which may also be leaking fuel injectors and flooding the cylinders with fuel but most likely is a clogged fuel filter try spraying starter fluid in throttle body and if starts its clogged fuel filter
Yes...check the pump, filter and output. Also check the ballast resistor for the pump. Stop pouring fuel into the cylinder...instead, use carb cleaner and spray into throttle body (excess fuel in one cyl will contaminate your engine oil). If it runs normally after you get it started likely the pump is good (unless you have problems at high rpm's under power) Regulator is likely good as well...default is to more fuel not less.
Try taking spark plugs out and then turn engine over, if water sprays fron cylinders then the reason it overheadted was head gascet fault, but once water is removed and spark plugs re-fitted then it should start. hope not head gascet tho.
1 make sure timing is good.
2.check all the sensors make sure they all plugged in(some cars has same plugs for different sensors make sure you gut the right sensor for right plug)
3. Pull one spark plug of and see if it has any fuel on it.if it does you might flooded the motor.
4if none of the above works you should do compression tests on the cylinders.
