A day or two ago my car started randomly fast idling (1500ish RPM) when warm, all the time. Sometimes playing with defrost/AC I could get it back down. Then it would sometimes randomly go back up again. Got worse. Car would fast idle but then randomly bog and randomly nearly stall when clutching/stopping, but not every time (earlier today). All seems okay underhood. Grounds/intake etc seems happy. So I decided to disconnect negative battery cable for a while to reset ECU and try it. Now, car will not start. Cranks wonderfully, but never even hints at catching. Medium fuel smell from rear at this time. My guts telling me the fuel pump. (could AIV or IAA cause a flat-out no-start?) What do you guys think? :? ---

Thanks DRE, that’s what I was thinking. I hear NO humming from the fuel pump at all but when I turn key to ON I hear a “camera flash charging” sound from the rear-underside of the car. One time I heard a liquid squirt sound from the same area at that time too, just once though. Fuse for fuel pump is good. ---

Check for spark man I had the same problem, and turned out it was flooded badly. The engine would crank extremely fast and I had no spark. There was fuel tho. ---

Well it turned out there WAS spark (i should have said this) but there was so much fuel on the sparks that I didnt see it. I dried off the sparks, and turned the motor over and over, left it overnight. I then put everything back together the next morning and boom, first crank it started up. Check your coilpacks because what it looks like is that the bad idle was caused by a damaged coilpack, and then now it wont spark at all because they are all damaged. I had the same situation as well, the idle was horrible, high and the engine was shaking like crazy. I had a misfire in cylinder 2 ( i knew because i removed the plug for the coil in that cylinder when the car was running, and there was no change in the idle). I then replaced that coilpack and boom, everything ran perfect, and even more high end power. ---

Coilpack? Doesn’t the KA use a distributor & wires? I must be missing something here…please explain. 🙂 ---

UPDATE. Car is still in the shop (since Sat. morning)… They are stumped. Car has spark & fuel at the cylinders. Compression shows 2 cyls okay (150psi), but 1 at 125psi and 1 at 100psi. Car has always “felt” good before this, I would’ve thought the compression was good, so i’m not too sure what to make of the results yet. Tried another MAF, no help. The car cranks like a champ but never fires at ALL. For all the cranking I tried, there has only ever been ONE cylinder explosion/fire. So basically, i’m stuck w/o a car for the time being, so if any of you have any other ideas, let me know. ☹ ---

Something very similar to my car happened last spring. I couldn’t figure it out and had it towed to a garage. They in turn couldn’ figure it out either and basically gave up because of how busy they were. Towed the car back to the house where I continud to play with it. Got pissed of one night poored gas in each cylinder and just cranked it while flooring it and swearing (yes my son was sleeping) and of it went! Only thing I could think of was that it was flooded and we all missed it. ---

Now that you mention it, I think cranking it with the pedal floored puts the car in a different mode or something…hmmm…like to clear fuel flooding or something… ---

also check spark plugs for raw fuel its cranking but there is no spark right? test the distributor for a spark if there is none you might need a new one. assuming that you have a ka. ---

So spark and fuel at all cylinders, but 2 are working well, and 2 aren’t? I don’t know a whole lot about engines, but from simple chemistry, if it’s getting proper amounts of fuel and spark, the only thing left is oxygen. Can anyone think of any reason why two cylinders wouldn’t be getting enough oxygen? ---

Yeah, something doesn’t add up, the mechanic might’ve told me something wrong. But when I come up with new ideas, I call him, and he’s already tried them…so i’m gonna leave it in his hands and let everyone know the results (keep the ideas coming though!). \<---- Baffled. :-k ---

lol and for that matter, you just said if there is spark and fuel then there must not be any oxygen. but inorder to create a spark there must be oxygen in the first place. ---

its actually a bannana phone… you require the long distance plan to make the bannana phone allow air in. so itll work properly. other wise itll hit the backside of the TB and will stop going because your still in a local area. GT ---

Sigh… I said not enough oxygen, as in something wrong somewhere along its path into those 2 cylinders. If it’s not firing properly, then flooded is the most logical conclusion, however in a combustion reaction both reactants must be present to a certain extent for it to go to completion, if there isn’t enough air, the result is the same as too much gasoline. Actually nevermind all that, I only know how an engine works from theory, so I’m probably wrong. But he did say he was completely out of ideas so I gave him mine. I’ll be sure to not do so in the future. ---

It’s up to the MAF to tell the ECU how much fuel to provide. [Next page](https://forums.speedlife.net/t/fast-idle-turns-to-no-start-solved/81876.md?page=2)
