first let me say this is the third time the car has done this so i replaced the plugs and wires about 5 months ago and it didnt happen again till today. i was going down the road headin to school when all of a sudden i started loosing power quickly. i downshifted kept it alive enough to get to a parking lot where it tried to keep running but shut off.

i checked on the engine and nuthin seemed out of ordinary so i got back in and tried to crank it but it just spun so i did the deflood procedure(pedal to the floor) and it started right up and ran just fine the rest of the way there and home.

i have new plugs and wires so i know that isnt the problem.

any ideas?

 

Wow, I don't think I have ever heard of flooding WHILE driving. The only thing I could think of is an injector stuck open all of the time and spraying extra fuel.

 

Ditto... You should pick up a used set of injectors off the forum or ebay for cheap and see if they help.

 

that was my thought too. i havent heard of a car flooding while driving before.

i thought it would be either the ignition somehow or the injectors....i need to get some 720cc secondaries anyway for my new rtek so i guess this gives me a good excuse to do it.

 

It sounds like something to do with ignition. You said your plugs and wires are fine, could it be a coil maybe?

 

I had the same symptoms and it turned out that the fuel sock fell off my pump in the tank and my fuel filter clogged up

 

Mine use to do the same thing... Until i realized the PO put the belt going to the water pump and alt on with the teeth pointing outward.

A contributor was a dirty fuel sock that I found 3 or 4 days later...

 

Fuel socks should be clean no matter what really. Unless the car sat for a couple years without draining the gas.

 

If the coil was bad the car would be very slow and sluggish.

 

well the coils are good. the sock is fairly new so the next is new injectors.

 

ok so my problem might have just gotten worse...

i drove to my girlfriends today to see her before i leave for a hockey camp and when i was tryin to leave it wouldnt start.

it kept turning over but wouldnt start. i did the deflood procedure and still didnt work.

im wondering if the injector(s) have fully gone out. anybody know what the symptoms are for injectors that malfunction like this?

 

change your fuel filter in the engine bay, i bet its clogged. that happened to me when the fuel sock fell off, start with the small stuff then work your way up.

 

well when i get back in town...if i can get it started and get it home then thats prolly what ill start with.

 

Easy way to see if it's getting fuel into the housings. Remove the upper trailing spark plugs, unplug the leading spark plugs, and crank the engine. If fuel is getting to the fuel injectors and the fuel injectors are functioning half way decent, you should see gasoline vapors misting out of the top plug holes.

Superior de-flood method...

-Remove all 4 spark plugs. Clean them with a wire brush, clean rag, carb cleaner, and an air hose or replace them with new ones if they are worn out. When you replace them you want them to be bone dry and shiny metal, no carbon or raw fuel left over.

-Unplug the fuel pump.

-With the spark plugs removed and the fuel pump unplugged, push the gas pedal all the way to the floor and crank the starter for a few seconds, wait 10 seconds, repeat 3-4 times. You should see big puffs of gasoline coming out of the spark plug holes if it is in fact flooded. Do this until the fuel vapor stops spraying out.

- Replace clean plugs, plug in fuel pump.

Let the fuel pump prime for a seconds and start the car! It works every time no matter how flooded the engine is!

 

I run premix on my GXL. Every few thousand miles I have to take out my plugs and clean them.

One day the car just wouldn't even try to start at all. Even with the standard de-flood method. The plugs were fouled beyond belief. Oil build up and carbon chunks. Wire brushed em and did the above method and it started right up and.

 

huh... dude i think my car is premix but before i get any farther wat do u mean by premix?

 

It's when you remove the OMP and manually add 2-stroke oil to the gasoline.

 

What he said

 

oh.. well is premixing ok to do? omp is what makes the rotary burn the oil without premixing is?

 

^^do some searching. thread jacking FTL.

on that note i am premixing as well and that might be my problem. im gonna do the complex deflood and check sparkplugs and such.

this is gonna be such a pain in the *** if i cant get it started.

you know after 3 years of owning this car and working on it for hours and knowing almost every in and out of the thing it still jumps up and surprises me.

thank you for all the suggestions. i have decided to park it as soon as i get it home and start tearing the fuel system apart and send the primaries off for cleaning and purchase the greddy 720cc for secondary and install my rtek 1.7

 

Not to discourage you or anything... but when I had my parts car engine running (the 1 rotor wonder, blown rear rotor) the ECU was sensing a huge vacuum leak in the rear rotor due to the broken apex seals. It compensated by pushing full throttle gasoline out of the rear rotor injectors. There was raw fuel spewing from the exhaust, and when I tore the engine apart there was a cup or so of gasoline sitting in the housing...

 

oh trust me my motor better not be blown. it a fresh rebuild still under warranty by rotary resurrection. i have about 7K miles on it.

 

ok so now something more major than what i though is going on.

i did the deflood procedure exactly like you stated and no gas was coming out. i hooked everything back up and took the spark plugs out. turned it over and still no gas ive checked the fuses and replaced the egi inj fuse because it seemed blown but that didnt change anything.

im at a complete loss as to what to do now. maybe a fuel filter but i dont see how that would cause it to completely not turn on. inless its completely clogged. its a fairly new filter so it shoudnt be.

 

Dumb question... Your positive it has a few gallons of gas in it? Can you hear the fuel pump whining when you turn the key? Might want to check your main relay. Located next to the TRAILING coil pack. Usually a gold color about 2 inches square.

Do you have a spare ECU laying around? Try swapping it. The ECU could be acting up.

 

haha ya thats the first thing i checked to make sure my gas gauge wasnt malfunctioning.

well ive decided to just suck it up and tow it home. ....i never thought id say this but thank god for geicos emergency service. their paying for my tow home with no deductible.

ive come to the conclusion its either my fuel pump or my injectors so im gonna replace both.

the fuel pump is less than two years old and its a walboro 255. im gonna order my injectors from greddy 2morrow and go ahead and start installing the rtek ecu ive had sitting around for almost a year lol. i guess this is a good time to finally get some much needed work done.

im so glad i have a motorcycle as a backup.

thanks Ncross. youve been a big help and maybe one day ill get to buy you a beer. lol

ill update this in the upcoming days as i tear the manifold down and get to the injectors to see what shape there in.
