98 prelude no start

I'm really sorry if this is somewhere on here but I've been looking for an answer everywhere and this is my dd so I'm desperate anyways
I have a 98 prelude that I'm having problems with. It started with I was driving down the road and it just randomly turned off then a few seconds later it turned back on. I drove home where it idled at about 300 rpm and died. The dip stick smelled of gas and some fluid is coming out of the exhaust not oil or water I'm assuming gas. It was getting spark and had the right fuel pressure so I changed the fuel pressure regulator. The plugs seemed a little fouled by gas. I can get it to kinda start every 10 tries or so but sounds awful and when you press the gas it dies even if you don't press the gas it will eventually die. I checked the compression and it's good. I pulled the fuel rail and checked to make sure the injectors were getting power with a test light and they were. I tried to see if the injectors were spraying gas by leaving one plugged in at a time and turning the fuel pump on and it didn't work. I'm not sure if they can't spray when not in or what. But it's hard to believe all 4 stopped at once. I tried to start it with some starting fluid and that worked it ran good. But I have no idea what to so next. Any ideas? thank you

Re: 98 prelude no start

You would really have to be dumping alot of gas for liquid fuel to be coming out of your exhaust, although if you actually have gasoline in your engine oil then it could be possible. What's strange is that the one instance you say you have gas coming out of your exhaust and your oil smells like gas but then the other instance it sounds like it's not getting any gas, seeing as how you said you can get it to start every few tries but it ran when you sprayed starter fluid in it. The injectors are not going to fire with the engine not turning over, the PCM has drivers inside that work in sync with the sensors that tell it when you have a cylinder about to fire, that is when the fuel is sprayed into your manifold. I have heard of the injector drivers going out in a PCM. I know there is a test for it and you may be able to find it here. I would also advise to check sensors that are responsible for calculating air/fuel mixture like your tps and map sensor. Also make sure that you do not have anything that is blocking your car's air intake..no air but a lot of gas isn't ideal. It almost sounded like at first that you may have had one or more injectors that were stuck open and then all the sudden you didn't have any gas...I'm assuming you do still have gas in the tank? Good luck man and update when you can.
