Car won't start need help (springs)

[christi]

So, after getting the motor together and everything properly hooked up (thanks secondgenpat), the car won't turn over. It tries but it sounds as if it's trying to flood. There is good gas, new spark plugs (they're all firing.) new wires etc. It sounds as if it's trying to flood but I don't know. Secondgenpat may think it's the Crank Angle Sensor but without him testing it or someone closer we are not 100% sure.

I don't have a way now to send a clip of what it sounds like since alex asked earlier.

Can anyone in the springs come look at it an please help diagnose this issue? Please?!

I'm one side panda ...I just wanna get this fixed.

If it were me (and its not, so feel free to ignore) I would:

Make sure the plugs are new, and if they have flooded AT ALL, they need to be pulled and dried. I use a propane torch to dry them, but you can do as you like
Make sure the motor is dry. By that I mean pull the plugs, pull the ECI fuse, crank a few times watching for fuel vapor from the plug holes.
Walk away and leave the engine alone for at least half an hour, preferably longer.
put the plugs back in
make sure. and I mean REALLY sure that the battery is charges, everything is plugged back in, and give it a go.


If you have spark and fuel, I have trouble believing it is the CAS, but anything is possible. There is a ground under the intake that frequently gets left off (or broken) and will cause similar issues. Injectors can also be a serious issue as they can get stuck open and there is not much to do but send them out and have them checked.

If you have no luck at all getting the car to start I can take a look at it if there is a way for you to get it up here to the shop.

Pat thinks it is the injectors too. Forgot about that. I may have to get everything removed on top again and get those sent in...I'll have my buddy pat in springs test OT for everything else before the injectors, of all else fails I'll get those cleaned.

Thanks for the reply don

Edit:
After looking at injectors rehab their new injectors for 2 are less expensive than the cleaning. If it comes down to cleaning I'll just replace. If thats the case does anyone recommend anything specified ?

I'm one side panda ...I just wanna get this fixed.

Sorry, but when you first posted this, for some reason I got distracted by you calling yourself a 'one side panda' and completely forgot about your car. After much contemplation, trying to understand what a one-sided panda might look like or what a panda that only stays on one side represents (assuming that there are pandas that only stay on one side of an argument while all other pandas constantly switch sides)... I finally realized that what you meant to say was that you are one SAD panda. Which totally makes sense cuz sad pandas are very sad. And you are very sad, so... using the logic I learned back in high school, you naturally are a sad panda.

Now that we've cleared that up, I can start thinking about your car. IMVHO (very humble opinion), I don't think it would be your CAS. In my experience, that sensor failing prevents the engine from even thinking about trying to turn over or allows the engine to start fine but results in random increases in the rev count while it continues to degrade until you end up with the first (no-start) condition.

But that's all I've got. Hopefully, I've shed some light into a dark and confusing world (i'm only talking about the panda stuff, of course).

Seriously though, best of luck.

tps...

[christi]

Ian, what's your reasoning behind the thought of TPS?

Also the reason why my last engine was not idling was cause a huge amount of vacuum leaks and wires unplugged. I don't believe my TPS is the problem. However I've been proven wrong many times

if you pull the plugs can you smell fuel? if so the injectors are firing or dumping. If not chances are there not doing anything, if that be the case get a noid light ( or led for those of us who grew up with macgyver) and test the injector wiring (do NOT use a test light!). sometimes the yellow plug (x-15) behind the passengers footwell on the right will come loose and you'll loose all injector power (happened to me twice). An easy way to test the CAS is to pull it and spin it by hand with the power on, you should hear either the injectors firing or the spark plugs firing, that'll let you know if its working. after that if all else fails try a bigger hammer.

after that if all else fails try a bigger hammer.

or burn the damn car. im pretty ****ing close to doing that to mine

a bad tps may or may not let the car start at times. a bad tps will cause the engine to flood. try resetting the tps. it should only take like 10mins.

god i hate series 5. so much electrical nonsense

[BRC]

agreed!

The S5 really does have a lot of electronic garbage that gets between you and the enjoyment of the car. The fuel maps are also rich as hell for some reason and the altitude comp is crap, so it runs even richer up here at altitude. As I cautioned you, you will not make best power OR see much benefit from the portwork/header/exhaust etc. until you have an AFC or similar to lean the thing out. Profit= in addition to more power, you will actually increase your fuel milage. Pocketful of win!

EDIT- also plugs that have been fouled even ONCE may not be able to start the car if it is even thinking about continuing to flood, IE if you flood it because of some mystery issue (coolant temp sensor, tps, injectors, bad timing, whatever), and you clean the plugs and put them back in the car will be very unlikely to start. NEW plugs are the way to go, but this can get expensive if you have not fixed the root issue.

i have the whole s4 t2 chassis harness everything down to the taillights if you wanna do the swap LOL

[christi]

So, I guess I did it backwards but was assuming that the issue of having a hard start would disappear when I got my new motor. Apparently not. So everyone (what seems) who helped me piece it back together, seems pissed at me.

Secondgenpat put the electronics and all the wiring/injectors back together. They're in the right place, atleast I trust his judgement on putting everything together correctly.

I won't try starting the car anymore until we clean the injectors, but are we SURE this will fix the issue? Will it be better to purchase or just get them cleaned/rebuild?

I think I'm just alittle stressed. All this work, and I'm back at squared one. I guess it's my fault for not doing it all at once, but I live and learn, I guess.

ian, thats stupid expensive =P

edit: I do know what sucks is that all this has severely killed my battery :l
Pretty much I just wanna get this fixed, get the car running, and not have to worry about it anymore... haha

don:

there is no way i can get the car to denver. I don't have a trailer to drive her up there, and I really cannot afford the extra expense to keep my car at your shop. So unless someone has a trailer to bring her up there to look at for a week, sure.. but if it's going to cost me a arm and a leg to keep it there for a week, I can't do it.... Even though I'd like to.
Or is willing to maybe, once I get the injectors cleaned, if still issues to come by and see what's wrong I dunno. Like I said, just a frustrating matter....

I will be in Co Springs over the weekend for Pikes Peak practice, so maybe I can swing by and take a look at it.

[christi]

Give me a ring then. I'm off Fridays, and work Saturdays until 6p , Sundays off. My buddy Pat that you met, Don, will be gone all weekend, but I'll be available to take a look at the car with you, as it's in his driveway. So let me know.. .when.

[christi]

The place where my car I'd at I won't have tools at all to work on her over the weekend. My friend is going out of town. Is there a possibility someone would be interested In hping me out Friday or Sunday? If don can't show.

A few people I spoke to said it may not be the injectors since the plugs are getting fuel. My battery is completely drained so I couldn't work on the car anyway as I do not have a battery charger readily available.

Ian some people did say that it could be the TPS and the fuel lines regular etc. Taken from my Facebook, someone recommended to try this before wastingoney on cleaning the injectors and it doesn't work:

"there might be a few issue's first try unplugging the Inline fuse for fuel cut off, then try using some starting fluid in the intake, if that doesn't work put a little bit of 2 stroke oil through a plug hole and turning the motor a bit until you get all of the rotor surface's covered. that will help build up some of the compression that was lost by the fuel soaking the inside a bunch.

EVEN IF you need your injectors cleaned it should fire up with starting fluid. if it can't fire up with starting fluid then work on it tel it does before expecting your nicely cleaned injectors to do anything. If you can't get it started up with this setup then there maybe something wrong in the ignition, but the starting fluid should be able to ignite even with low spark."

I'm no where techy to safely do this without messing something up. That's why I'm curious if someone would be willing to come help me this weekend.
