I have had ny rxy for about 4 months with a bad motor. I found a used one and put it in. I finally got done with it about 1 week ago and started it right up. Wonderfull. it purred for about 10 min no prob so i shut it off and went in side. came back out to test drive it and craked it ...the rpm's went up but the car didnt start. did that 3 times then it decided to just turn over and wont do any thing else. it has new plugs wires and coils. ANy help would be appreciated.

If you look on the driver's side in the engine bay you should see the main fuse box. Pull the EGI COMP and the EGI INJ fuses out and remove the trailing spark plugs from the motor. Then crank the motor over for 20-30 seconds. What you are doing is disabling the fuel pump, and the spark, that way any fuel that has built up will be expelled through either the trailiing plug holes or the exhaust. The car may try and start without the plugs in. If it does catch turn it off. Replace the trailing spark plugs and wires, and replace both the fuses and try starting it again. This is a fairly easy trick to do. If it doesn't work let us know, and we'll see what else we can throw at you. Welcome to the boards, and the rotary community by the way.

you dont need to mess with that if it's an S5, just put the peddle to the floor and that'll cut the fuel.. if it only does it after it's been run then shut off, then i'd send your injectors out and get em cleaned

ok, tried the trick with removing the fuses under the hood, and taking out the trailing plugs. The car will turn over, but still wont crank up. You can fumes of fuel after trying to crank it. And sometimes it will crank up for just a second, but then it will die, even if i put the peddle to the floor while it cranks it doesnt make a difference. I had somebody tell me it might be the ecu messing up. Please help me somebody.

keep trying to start it the way where you take the fuses out. if it starts for a second it should be almost there and cranking it 20 more seconds with the egi fuse out should get it going.



ps just remove the fuse in the main fuse block thats labeled "EGI"

In an S5, flooring the pedal during start-up will cut the fuel. Just let it sit for a while, pull the plugs, dry them off and let it sit. You should test the coils/ignitors to see that you are getting spark as well.

Change the plugs after that too.

What year is the car? Try cranking it for a longer period of time. You should also test as said to ensure that you have adequate spark. A quick cheap way to do this, is to get an extra good spark plug. Pull one of the plug wires, and attach it to the good spark plug, place the plug on the side of the engine compartment, and have a friend turn the car over for a second, you should see the plug spark. Replace the plug wire and try each one. Make sure that you are not touching car, spark plug, or plug wire, when it is being cranked over. And make sure that you have all of the plug holes filled with a spark plug, you don't want fuel getting out while you're testing for spark. Good luck.

just test for spark by sticking a screwdriver in the end of your spark plug wire and hold the screwdriver shaft a 1/4 inch away from the block to see the spark jump

Your a brave ****. I don't trust the properties of rubber and plastic that much.

be a man, it doesnt hurt that bad when you get shocked https://www.nopistons.com/forums/pub...#>/biggrin.png

When it shocks the **** out of you it will only make you piss yourself a little bit...

holding the end of the wire will most likely shock you but if you hold it a little up the wire theres no problem.



dad says grandpa just held the wire and let it shock him to check for spark

lol



To get back on topic, did it work, is your car running yet?

yeah, its only 40,000 volts.... thats it

ive been shocked by them before and it didnt feel like 40k volts, maybe thats bc it was diluted by the insulation

I read that and did it wrong though. I thought I was supposed to hold the spark plug up and touch a screwdriver to it.



Hurt kinda bad.

so it hurt when you held a spark plug and a screwdriver together?

Just put your wang on it.

everybody wangprun!

Alright, i got spark, fuel and air, it still doesnt want to start.

i didnt replace the pleugs, they still looked brand new and have only been used since the swap. this is geting frustrating.

I tried all the taking the plugs and fuses out and started it to get the extra fuel out. Got everything back together, and it cranked right up, but as soon as i turned the car off and tried to start it back up it wouldnt. I repeated the spark plug and fuse thing and it started again. The car is just running way too rich and is flooding it out. What could the problem be?

There are several possibilities. The first thing that comes to my mind is that the injectors may be leaking when the car is off. This would cause the car to flood while it is sitting, making it hard to start.

the guy I bought my car from had the sam problem with my car. He got a fuel pressure release valve or something and it seemed to keep it from flooding. But I am new so I dont really know.

a fuel pressure relief valve? do you put that inline on the fuel hose?

Also, when I leave the ignition on, after about 10 second there is a awful continual buzz that goes off. And when I hooked the battery back up the other day one headlight popped up and went back down and my horn beeped at me. with all that crap and way too much fuel into the cumbustion chamber, could it be a electrical problem?

wire your fuel pump up to a switch.

fuel pump works fine, already checked that. keep giving me some ideas,

i need this car running very soon.

Clear the fuel lines by running the car until it is warmed up then either pulling the fuel pump connector, which is located on the driver's side speaker tower. Or by pulling the fuel pump relay which is a yellow connector underneath the driver's side dash, it is a box that is about 1inch by 1inch. And let the car die. Then pull the injectors out of the holes in the manifold. Reconnect either the fuel pump connector or the relay, then have someone prime the lines by turning the ignition to the on position, don't start the car. Then look and see if there is any fuel coming out of the injectors. Make sure that they are connected to the fuel rail securely.

https://www.nopistons.com/forums/pub...1047683358.gif The injectors are fine. still too much fuel, flooding out engine. What would cause my horn to beep and headlights to flash when I connected the positive cabal to my battery? and why is there a constant buzz when the ignition is on for more than ten seconds. Could it be an electrical problem that would also effect the fuel into the combustion chamber?

Alarm going crazy?

Pull the ecu codes, and tell us what you have.

try this, I think he may have used it to fix mine.

He mentioned above that his injectors are not the problem. I wouldn't use that part either, that's just as good as putting a bandaide on a broken leg. You aren't fixing the problem at all, you are diverting it, the problem still exists.

just a sugestion check the timing on the electronic ignition. if u pull the ignition u will see a dot and a line to align this dot on the bottom gear of the ignition. they shoud align i belive when ur timing is on tdc. also u could check the catalitic converter if u have one and is cloged then this will happen. just shooting in the dark. if it helps let me know bcause i have other in line to keep shooting .

I checked for voltage to the injectors and there is none. any suggestions?

With the key on, one side of the injector plug should be 12v.

So either the injector fuse is bad or you have a harness problem?



<edit> This dosen't match up with flooding, but you could have both.

If the injectors are leaking it does.
