ok my car has been in the shop for a few weeks. when i took it it had a drain on the battery and i would have to jump it off everytime i tried to start it. so i go up there today to see how its going and they tell me that it wont start. they put a new battery on there bc the old one was "sweating" so anyways, they fixed the drain when they fixed the bumper and stuff. i go out there to try to start it up and the battery is strong and it tries to start but it wont. its turning over but it wont fire. to me it seems like its not getting gas but thats just me. the plugs are new so its not that. i dont know what it could be. please tell me everything it could be. im thinking maybe the fuse for the fuel pump or something liek that. i dont know. i guess they are gonna look at it to see what it is since it wasnt doing that when i took it in there. thanks for your help guys.

pull the plugs and see if it flooded, it probably has flooded from them trying to start it. Unflood it you will be fine.

have you ever flooded it before? could be that. maybe the shop idiots started it up...let it run for only a few seconds...and then shut it down...........causing it to flood.



no biggie...

pop the hood...pull out the EGI fuse

get in the car...push the gas pedal to the floor and crank the car for 10 seconds

go put the EGI fuse back in

get in the car, crank the car WITHOUT pushing the gas pedal



it might start after one try...it might not. if it doesn't...pull out the EGI fuse again and repeat the procedure...you might have to do it 5 or more times to start it...



but maybe you ruled flooding out already?

i didnt rule it out but, i didnt try to start it for very long so i know i didnt flood it. i dont think they did bc i dont think they messed with it today. i will try that though. thanks guys, any more ideas??

when it sits for a while it can also lose compression, did crank over fast?

And if it didnt start even after a few tries of trying to start it, its flooded, it doesnt take much because the wonderfull engineers at Mazda didnt put a cut-off in the fuel injection system like every other car made so that if it doesnt start after a few seconds it will just keep dumping fuel, while other cars cut the fuel off until the car starts.

it hasnt really sat for that long. its sat longer than this before. if it has lost compression thats a rebuild isnt it? at this point i hope its flooded

its flooded, puch the pedal all the way down at it will cut the fuel for you



mike

noooooo, no rebuild, dont get hasty, lol

You will just have to crank it with no fuel until it sounds normal, then

try it with fuel.



You flooded it, trust us and do the unflooding thing and impress the body shop with your knowledge.

yah if they tried to start it with a weak battery it will flood



mike

I agree with Erik, but if I remember, you have to crank with pedal down for 20 seconds, put the fuse back in, crank without depressing pedal. I had to put ATF in the plug holes to build compression on mine, but it sat for over 2 years.

Oh, and tell the shop not to start your car unless they will let it get up to operating temperature. Then it wont flood.

i forgot to say anything about letting it run when they start it. they wont do it but i will tell them anyways. im going up there tomorrow and i will try to start it. where is the egi fuse at??

The egi fuse is under the hood in the fuse thing( cant think of a word for it). Its on the side with the battery atached to the strut tower. Its a black box.

ok its in the main fuse block. if it sits overnight with no one messing with it should it get unflooded?

NO!



you have a 89-91 all you have to do is floor the gas pedal it cuts fuel. if its really really flooded. pull egi fuses and crank it like 10 times for 5 seconds... then reinstall fuse should start right up. i bet there is a gallon of gas in the engine https://www.nopistons.com/forums/pub...DIR#>/wink.png

thanks man. i dont know if i should take your advice bc you know so much or not bc your car isnt running!! hehe jk i know youre the god

btw, letting a rotary sit after it's flooded is not a good idea, get that puppy started asap. or you're gonna have to pour some MMO or 2 stroke oil into the spark plug holes and crank it a bit to get some oil in there, if it's gonna have to sit for a while.



otherwise you will likely have corrosion problems, the flooding will wash away all the lubricating/protective oil.

ERIK has the right idea!!

that problem is common on 2nd gen RX-7's. It's caused by the car getting started while cold and shut off before the engine has a chance to warm up.

ok i tried the flooded thing and it didnt work. would it make any difference that the bumper is not on the car??

it shouldnt, i would try one more time, and then put some oil in there



mike

Ok, so is the unflooding done with the gas pedal floored or not touched? On my S4's, it always works with no pedal.... some guys are saying it only works with pedal.



Which is it??



So many threads get conflicting stories and I think its usually the S4 vs. S5 issue or the turbo vs. NA issue....

I just flooded mine, and I had to pull and replace the fuse like 7 or 8 times...it eventually needed a jump, but it eventually worked

did you just crank it with the plugs out for a while to spit all the fuel out?

Car wont start with the AFM disconnected or the tube going to the throttle body, I cant see why they would have disconnected that for the bumper though ( only thing I could think of for your bumper question )



It might take a while to get the car started, pull the plugs and crank it with the fuses out, some fuel should spit out of the spark plug holes. Do this for a bit but give the starter a chance to cool off while you are doing it.

Then put the fuses back in and try, if it doesnt IMMEDIATLY start, pull those fuses again, RIGHT AWAY so you dont flood it yet again. If it doesnt start after that, use some Marvel Mystery Oil in the spark plug holes and let it sit overnight then try in the morning, it should work then.

one last time, I cannot say this enough: if at any time your car doesnt start right away it will flood itself out.

the s5's have a full range tps, so when you floor it while cranking (the ecu know you are cranking) it cuts fuel. the s4 does not do this. it is still better to floor it, you want to get air in there



mike

am i supposed to be taking more than one fuse out? i did try it for a long time. never did take the plugs out though. they said they were going to look at it.

I personally pull both fuses out when trying to get the fuel out

I see no reason for spark when you have the plug wires off anyhow.



Then I usually reach under the dash and pull the harness while I try to

start the car ( with the fuses plugged back in ) when it starts I can just plug it back in, this way I can do it by myself.



You can also plug the harness in for a second to give it a little fuel then unplug it and keep cranking, there should be enough fuel in there to get it running. Once you know where the harness is, you can hold the harness with your right hand, and use your left hand to turn the ignition key. It will be even easier for you because you dont have to push the clutch in so you can probably kneel down on the floor next to the car, find the plug and use one hand to disconnect it and reconnect it and with your other hand turn the key.

im really lost i dont know what you are talking about. what harness? what fuses?

the fuses under the hood

and if you look to the right of the steering column there is a wiring

harness with like 6-8 wires, one side of the harness is yellow I believe, the wires are all different colors, but I can tell you there is a blue wire in it. I really should take a pic of the harness and it should be pinned so everyone knows what it is.



Pull the plugs, and pull the fuses, crank it to get the fuel out. Plug the fuses back in. Kneel down next to the drivers side, look for this harness, unplug the harness, crank the key, when it sounds like it will start, plug the harness back in while you are still cranking it, it should start, it if doesnt start, unplug that harness again and keep cranking, make sure you have a battery booster on the battery to get it good and strong. When it starts just plug that harness back in again. get ready to rev it to clear it out and you will probably smoke the **** out of the shop. Then when you get the car home, change the plugs and the oil.

if it wasnt 11 degrees out I would take a pic, ah **** it, ill take a pic now.

thanks man. what fuses under the hood though. i was just pulling the egi fuse

I believe the other is the EFI , they are right next to each other, maybe you arent pulling the right fuse, did you at least pull the one thats 2nd in? I forget which is which, im sorry, lol.



Anyhow, here is that pic, kinda blurry, its hard to take a pic looking up from the floor, but as you can see, one side of the harness is yellow, and one side is white, you wont have those red wire ties, I use red so I know which ones I put there should I ever have to go back to stock wiring. This is to the right of the steering column, a little above it.

ok thanks man. i only pulled out the one that was labeled egi. which ones do i have to pull out exactly

pull both of them out, they are right next to each other, unflood the car for a while with the spark plugs and the fuses out. Put both fuses back in and use the plug under the dash like I said. remember if it doesnt start right away, pull the harness apart. Try starting it, and when it does fire up only then keep the harness plugged in.

i was pulling the one on the edge out. it said egi. thats the only one i pulled. the car is going in for paint so i wont be able to mess with it for a day or two. whats the harness do?

go back and read what I posed earlier, if there is still a question, let me know. Basically after you pull the spark plugs and the fuses and crank it to get fuel out of it, put the fuses back in and try to start the car, if it doesnt start RIGHT away, reach under the dash, seperate that harness I took a pic of for you, and try to start the car, when it finally starts plug the harness back in, you can plug the harness in for a second here and there to give it some fuel, but dont let it flood.

By the way, I think the fuse you should be pulling is second in, not the one on the edge, but I could be wrong, its been so long since I flooded one out.

the second one in is empty i think. i cant remember. i would go look but its not here. what are the fuses im pulling for? that way i can be sure to get the right ones

ok what you want to pull is the first and second, i went to my car to look.

the empty one is 3rd from bottom
