well, first time this has happened. i get into my car today and it wont start, it just turns over. im not sure if its spark or fuel. it drove great last time i drove it yesterday. then all of a sudden.. nothing. the fuel pressure when i cank it hits 25 psi, which is low, then it steadily drops to 0. i know my fd coils were wearing some as i get some spark blowout at anything above 10psi. anyone have any ideas, or where to start diagnosing.?

 

anyone? up^

 

Have you started with the basics like making sure you have a good/charged battery? I've seen batteries before that had enough power to turn on lights and a radio, but not start the car.

 

Yes, it turns the motor. In fact the motor turns freely. I called rotorsports racing which is near me, and they said sounds like flooding. Im ganna try and de flood the thing coming up this week... i need new plugs i guess... is there any apparent way to find out if it is flooding other than just going through with the deflood... ive never flooded it before.. acutally, i dont even know how it happens. rotorsports said it may be low compression.. but it drove find the last time, i know they can just go out like that, but i started it monday and it idled fine... that actually was the last time it was on.



BTW, thanks for the reply.

 

Like I mentioned, I've seen a battery which wasn't strong enough to start the car, so at least verify that your battery is fully charged.

After that, I would proceed with the deflooding procedure. If its been a while since you changed your spark plugs, now would be a good time. If you have access to an air compressor, you can get a spark plug cleaner for about $15 and just clean the ones you have.

 

i will try to charge the batery, or start it with jumpers hooked up... that may be likely because it has a oddesy battery in it, and i know the cold amps of that are lacking. other wise i would use new plugs, i have 9's all around and i have heard they tend to go out easy. i will update after tonight.

 

dang it... i hook her up to my wifes car and tried to start her... nothing.. jsut turned a bit faster... its turning as fast, if not faster when it was fine...


now, i pulled a lower plug, and it REAKS OF GAS! is this normal? cause i really dont smell my plugs when i pull them. also, down deep inside the plug it looked slightly wet. i went ahead and pulled the other lower plug to dry it out inside a night. so, hows it sound? is this flooding?

 

So far it sounds like you have a low battery and the car is flooded. I would follow the deflooding procedures and jump the car again when you try to start it.

 

well, it wasnt a low battery, it really didnt do anything, and it turns normalls... im making over 13v. is that characteristic of flooding when it smells like gas?

 

If hooking it to your wife's car makes it crank faster, then you are a little low on power. However, just getting more power won't fix a flooded car. My suggestion is as above in my last post: follow the deflooding procedure and use your wife's car again when starting it up.

If you want to do something other than that, go for it.

 

-check fuel and pump....pull the main fuel line going to the motor on the driver side. Have some on turn the key to the ignition position and see if its spitting fuel. If it does ur getting fuel and pump works.

-Take battery to atouzone and get it load tested. Make sure its not a bad battery. My battery worked great then died...the car sounded like it wanted to turn over but wouldnt. Made it look like it was flooded but wasnt. If battery is good check and clean plugs and wires(U can check for spark before u put them in). Make sure its not flooded and try starting it and see what happens.

-If it still doesnt start last but not least check compression. So far I havent had to go that far....so hopefully u dont have to either. Good luch...tell me if u find another solution to ur prob.

 

tomorrow i am going to try deflooding it. hope it works. i dont thing its low on compression. it pulls over 400 inhg at 930rpms. and did last time it was driven 2 days ago. also, i know the fuel pump is working, i am making normal fuel pressure on the gauge when turning it over.

 

Well, I tied to deflood this thing... i pulled the old plugs... they looked bad and reaked of fuel. so i bought new ngk rs (all 4 9s). I pulled the EGI fuse, and turned it with all plugs out for 20 seconds... tried again for 10. then let it sit for 1 hour. I tried t turn once more for about 10 seconds. then installed the new plugs. i put the fuse in. then i get in, pray, and turn it... it just turns, same as before. i hook it up to my audi s4 to turn with it jumped... nothing. i pull the plugs after the fuse is out... and the new plugs reak of fuel... fuel practically dripping out of the lowers, and they had alot of gunk on them. i am re trying the deflooding proceedure, i just let it turn for well over 20 seconds. getting fed up with this ****.


Am i doing it right??? anything i can do differently? should i let it sit more time? also, what do i do to the new plugs to clean them?? they have alot of fuel, gunk on them..


also, ANYONE HEAR CHARLOTTE WANT TO HELP OUT?? I have beer... emmmmm beeeerr.

 

Did you verify you are getting spark?

 

not yet... how it this done? pull a plug hooked to a plug wire, touch to intake to ground and bump key?

 

Take a look at your egi fuse in the main engine fuse block under the hood. If it is blown the car will do what your explaining. Just a thought if you have not looked . G

 

how do you tell if its blown? btw, this is your friends old fd from st. augustine. the silver one.. im about ready to take this to rotorsports and let them fool with it... there goes my new wheel money.

 

It wont be the big yellow one.Go in the smaller fuse box next to the one your looking at. The single 5 strand. I know your battery is relocated. Should be between the box your looking at and the headlight. It used to ride on the + side of the battery when stock.There is another egi. Sorry for not being more clear. The cover says main, head, EGI, retractor, B2. It will be 30 amp. Look to see if it burnt in the center or broken like any other smaller type auto fuse. Good ole Jason's car. Dont sweat it. Take one step at a time. G

 

I would even pull the retractor one (for the headlight motors) and switch it. Try to start car or pop headlights when switched or both to see if fuse is working for sure. Good luck. G

 

IIRC, if the EGI is blown, it won't allow the fuel injectors to power on in order to drop fuel into the chamber (i.e. that why its usually pulled to help deflood the car).

 

G,

thanks so much for your reply. I pulled an checked the EGI fuse in the smaller box. I put it in the head light spot and they went up and down. then removed it and tried again and they did not move. So i seems that the fuse is ok.

onward, my coils did seem to be breaking up spark at anything above 11 psi. so tey were wearing out. maybe they burned out? when i check spark in my other cars. i pull 1 plug and touch it to the motor and have someone bump the ignition and look for spark. is this ok to do with the rotory? im guessing this would be my next ste is to verify spark for both the upper plugs?

also, i just found info where people use wd40 or ATX trans fluid to build compression by spraying into the pulg holes before reinstalling plugs after the deflooding. should i do this??

 

flooded fure sure. When doing the deflooding procedure dont give up easily cuz it can take a while at times.

 

gatcha. i will dfinatly try more times.. make sure my car is hooked up to the audi for max power, and the compression techniques.. however, i may not have time for a week or so... grad classes are kicking my *** with time.
