91 Honda Prelude 2.0si... what's wrong?

Hey guys,
I have a 91 Prelude that has been sitting in the garage for more than 1 yr. This morning, I tried to start the car but it won't start. Then I realized that the fuel tank is empty(guess all the fuel has vaporized)? So I added 2+ gallons of fuel into the fuel tank and it still won't start... what could have gone wrong?

I know anything can go wrong with a car but before I let it sat in the garage for storage, the car was running almost perfect.

Car has about 140+k miles.....

When I try to start the car, I can hear it crank but the car just won't start. Spark plugs too old?

I when to a auto part place and guy told me that the main relay could be out. Can a main relay just went dead not driving a car?

What else can I check?

Cheers
andy

Hey man... thanks for the quick respone... I knew the battery was dead so I was jumping the car with my other SUV. I can see all the light and electronic stuff running, the car crank... but just won't start.

I'm pretty sure in the beginning was the empty fuel tank, but have added 2+ gallon gas into the gas tank and I can see the gas gauge rises.

thanks

You might try turning the key to the on position and letting it sit till the check engine light goes off then turn the key off and do it again a couple times then try to start it!! This will allow the fuel pump to get gas to the injectors so the car can fire!!! Maybe??

Yes prime the system and also listen for the "hiss."

Your starter could be bad as well...next time if you are going to park any car for an extended period of time, remove the battery.

pull the plugs out and ground them off individually and make sure they are arching, if they are then you're getting spark so the other thing to worry about other than that would be fuel, so turn the key to the on position and make sure you can hear the fuel pump prime

By the way, how can I ground the plugs individually? Sorry if it's a stupid question.

By the way, where is the Main Relay located for the 91 Prelude 2.0SI? And how does it look like? Sort of brown color right? next to the fuse box under the stering wheel?

just pull the plugs out one at a time when you pull one out put it back into the boot then ground the threads off to something like the valve cover studs and get somebody to turn the car over for you and you should be able to see the blue spark or arch in the gap of the plug, do that with each plug you should have a solid blue arch and you should hear somewhat of a low tick each time the plug sparks

Guys, is the fuel pump internal or external to the fuel tank? Where should I pay attention for the hissing sound when the fuel pump activated?

Turn the key once and stare at the dash.
Then turn it again/dont crank.
~It should sound like it's coming from behind it, dont focus on anything...

lol, if you can hear the fuel pump hiss in my Volvo, then you can def. hear it in your Prelude lol..

I have pour 2+ gallons of fuel into the tank and 4 days later, the fuel is gone? I still have not yet able to get the car started. I have try listening to the activation of the fuel pump and I believe I heard it......

Why is the fuel dried up? leak?

Hey guys...
I first check every spark plug, they all have spark so the ignition system was good.

I got the car started and let it sit idle for 10 mins. Then I change the oil but the oil filter. I then let the car run at idle for an hour and turn it off. I'll change the oil and oil filter tomorrow.

I guess the fuel didn't vaporized because the fuel gauge quick working. I thought it's empty tank so I keep pouring fuel into the gas tank and then it gets overflow?!?!
How can I fixed the fuel gague? Why was it working a week ago and now it doesn't?

By the way, the tail light is on all the time? how come? The moment the battery is hook up, the taillight is on?

Help guys..

Cheers
andy

is it both tail lights or one tail light and is it the brake light or is it the running light?

It's both the taillight and the brake light. It seems like it thought the brake pedal was compressed.

Should I look under the driver side dash board?

Alright guys, thanks for all the help and it's about time to give some update.

Let me start from the beginning...

The car has been sitting in the garage for a little more than 1 yr.

First thing I did, I drained the engine oil(without changing the oil filter)

1) Battery dead - got it replaced.
2) Can't get the car started - Fuel Gauge showing empty so I added a lot of fuel and eventually overflowed out.... (the fuel gauge is dead) LOL
3) I followed the instruction given to check if every spark plug was getting spark and it all check out fine.
4) Keep turning the key to on(NOT START) to see if the fuel pump activated and it does. I kept doing it for few times to make sure the fuel rail is pressure and filled with fuel.

here is the magic moment... I start cranking it... it responed better... I tried doing #4 a few times before I crank it... FINALLY, it started... but the engine was a bit rough.

The engine was shaking(the engine ran almost perfect before I stored in garage) but then I was thinking it could be due to bad quality fuel/ injectors need some cleaning boost. Went to autozone, got myself a bottle of injector cleaner, pour it in to the full tank of fuel, crank start the car again... the engine continue to run rough(shaking) for maybe 30 secs and it start to stablelize itself...

5 mins later.. it running like a champ!!!!

I turned off the car, let it cooled down, pour a cane of engine cleaner in there and crank start the car again and let it idle for 5 mins. Change the oil and oil filter.

Voula... the car is back to normal.... it sounds sooooooo good man... sooooo smooth... I'm just glad my 91 2.0SI is up and running again man... it was the car I drove through my college years... it's my buddy!!!

ok.. I still have a small issue... I purposely seperate this with my previous post.

1) During the cold start, I can hear the sharp squeeking noise coming from the... well.. not too sure exactly where it came from.. but it sounds like the alternator... it's making this high pitch squeeking noise.. and if I rev the rmp to to 2000+ a couple of times.. the noise went away...

If I turn off the car after it warm up, and crank start it again, the noise didn't happen.

What can be the problem here..? I remember having this problem before and the mechanic helped replace something(don't remember what it is). Any idea guys?

2) About the brake light that's on all the time, it's a small piece of rubber/plastic thingy that sit between the brake light switch and the brake pedal. Should be an easy fixed on this.

3) Fuel gauge - The fuel gauge actually work the first time I pour gas into the tank, then it went down to empty a week later. That's why I thought my fuel tank was leaking but it wasn't. Now that even I have a full tank of fuel, the gauge is showing empty... where should I look guys?

Cheers
andy

The squeak problem is most likely your alternator belt!! When they are cold they tend to do that!!!

So there is nothing I can do about it? Is it too tight? or... I mean.. I have to just live with it?

there is belt dressing you can put on your belts....having a car sit like that without every turning it over/starting it is not the greatest thing to do. Batteries die, belts & tires start to dry-rot. moisture enters into the exhaust/engine etc. Your rotors are most likely rusted, hopefully your pads are not stuck to the rotors as well. Check your hoses to see how they are as well. Check your airbox to make sure no critters have moved in as well....check your fuse box and make sure it is clean and no fuses have rusted and gone bad as well......drive carefully & easy with it for a day or 2 until you get all the cobwebs out of it so to speak (-:

Speaks the truth. My car has been sitting for a little over 2 months now with a bum clutch. Already all four of my rotors are rusted to hell, but that's alright I'll be puttin' some powerslots and hawk pads on there come spring time... Try the belt dressing for your squeaky belt, if that doesn't work, simply replace the belt (not too expensive).
