Ok heres my problem. Lately when I try to start my car, it wont start. It would crank but nothing else would happen. My friend told me try to tap the starter to see if it would start. I dint have a flash light so I couldnt see the starter. Some guy came up to ask if i was ok and if i needed help. I said sure. He said try to start it. I did and the same thing happened. So he went into our local super market while I called my dad to see what he said. My dad said he would look at it when he got off work. The guy came out and he said if I had any luck. I said no. Then he told me to try to floor it while i start it. It worked and out of the exhaust came a huge amount of smoke and reeked of gas. I asked him why did this help. He said the carb. was flooded. I told him it was fuel injected. So he said oh. So my question is what is wrong with my car to make it not start until i floor it or just step on the gas a little.

 

The car i drive now is my 92 lx 5.0 not my old 2000 gt in the picture if it still shows up.

 

Well flooring it just allows the throttle and everything to open up, so the smoke out the back end probably wasnt a big deal if you have exhaust. Otherwise it sounds like an ignition problem, dead battery, or air/fuel ratio problem. Check air filter, MAF, TB, injectors, and fuel pressure regulator as well as fuel pump.

 

well i just got the car and the only exhaust mods are the flowmaster 2 chamber mufflers. not even sure if its the american thunder cat back cause the tail pipes look stock. does it mean anything that the check engine light will flash on and off every once in a while. i mean it just started doing it, its weird cause so far it only happened twice. 1st time was yesterday night and second time was tonight and get this. both times happened in the super markets parking lot. so i am very confused and when it does start the first time it hesitates and then it idles at 1500 to 2000 rpm for about 10 seconds and then dies down to around 900.

 

and gas mileage is down to about 150 to 160 to a tank from about 220

 

You haven't said anything about it being hard to turn over, so I have to assume the battery is good. I also have to assume it's warm when it starts as you've been in a parking lot i.e. you've made the trip there.

Now, going on those assumptions lets proceed. I'm having to make a lot of guesses but this might be a starting point.

I've sure you've heard you need three things to start, air, fuel, and spark. You've got some spark as it starts when floored. You've got air as it continues to run, and you have gas as it will start. The part that's missing is mixture. I'm guessing it starts "easier" when cold because its basically choked i.e. it's rich (lots o' gas, little air). After it warms up generally you run leaner i.e. less gas and more air. When you floor it your forcing a "rich" mixture again.

A list of things that might cause this...
Unplug your MAF next time and see if it starts easier. Puts it in failure mode and mixture is determined by throttle position.
Could be the IAC, but I don't know a good way to test it other than an OHM meter.
Check your fuel pressure, which will test out your pump and pressure regulator.
Check for vacuum leaks.

That's all I got.

 

the super market is no more than a half mile from my house so it couldnt of warmed up that much. it started up this morning as ussal. hesitates to start than when it does it idles at 2000 rpm for 10 seconds. what i mean by hesitates. when i start it and stop turning the key it will take about 3 seconds and then the idle goes up to 2000 rpm. then i went to pick up my best friend to take her to work and i turned off the car. then when she was ready to leave it started with out a problem. her house from my house is 7 miles. only hesitates when its cold. only had the car for a few weeks and those two nights we the coldest.

 

I'd still try disconnecting the MAF and see if it helps. Be warned though, it acts a little squirrly w/o the MAF, especially in the lower throttle range!!

 

lol. what do you mean squirrly. and would it cause any damage.

 

Squirrly meaning that when you let off quickly at low speeds it jerks and sputters like a kid learning to drive a stick. The throttle position method is less exact than calculating based on air flow, so it tends to "seek" the right mixture a little. Won't cause any damage other than hurting your pride if someone catches you.

Just thinking about the cold thing...could be the temperature sensor is out of whack. Could be messing with the mixture as well.

Just FYI, you will get (eventually) the engine trouble light. The 92 is OBDI though...probably get it right off.
