I just changed the dizzy yesterday and tried to install a new o2 sensor but the old one wouldn't come out so i just plugged the new one in and taped it to the dizz till i can find a ziptie till i can get the old o2 sensor off or find a header.

checked all the plugs and checked fuses. the car had started just fine several times and as i was driving home from church it just shut down all sudden like and will no longer start.

need help asap!! as i cannot afford to have it towed.

i'll try resetting the ecu for now, to see if that will at least get it home.

could it have to do with the fact that the o2 sensor is reading the air in the engine bay and not reading the exhaust? i would think if that were the case it would be throwing out a code of some sort but there are no code!

tell me what you think will also post in tech

 

are you getting fuel and/or spark?

 

as far as i can tell i am. it sounds like it's trying to crank but it's just not getting there.

i thought for a moment it could be the timing but were that the case wouldn't it have been a problem right when i first tried to start the car?

i'm gonna try to get it started in a few minutes i had to get home and change out of my suit.

 

try to connect your old sensor back up for know

 

i'll see if i can do that. only prob is (and i know this was stupid but it's too late now) i cut the wire off on the old one so i'll have to splice it to get it back on but i'll make sure i have the old sensor when i go back thanks.

 

and check if your gettin spark and feul and if you got gas in your tank

 

have about half a tank of gas. will check the spark and fuel.

thanks for the quick responses i'll post when i get back from tryin all this stuff.

anymore ideas are still welcome. i'll find out if it'll start here in the next hour prob.

 

You shouldnt have cut the wires. Try to put it back to how it was before.

Also look at the car when its trying to start, if the dizzy is moving that means you put it in wrong. Take it out and flip the fin 180 degrees.

 

well i checked it out and i'm getting fuel but apparently no spark. like i said it had been running then it just shat out on me at an intersection. tried resetting the ecu and tried rewiring the o2 sensor. of course there had to be more than one way to do that so i tried both ways and no dice.

i checked for spark however i could think of and there was none. i checked all of my fuses and they're all good. all wires are plugged in. i don't know whatelse to do or even anything else to check.

more help would be great, thank you all for your quick response already. h-t rocks

 

heeeelp meee! bump

 

Ha. We just did my friend's EG. Got a new distributor and everything, put it in and it didn't fire. We pulled the distributor off, flipped it 180 degrees, mounted everything back up and it fired right up. Try that first.

 

that's the thing though i had it running just fine. i drove it to church and started driving home got ready stop at a light and it just stopped running and won't start again.

i put in the z6 this summer and had the problem with the dizzy but it never started then. i turned it 180 and boom, started right up. my dad suggested it might be the dizzy can the shaft in the dizzy break?

i just got the thing wed i'm pretty sure it was working before it was sent to me.

could the problem be in one of the relays?

 

bump again for fast help

 

bump so i don't have to get my car towed

 

funnily enoucg i did the dizzy / rotor & O2 sensor yesterday.

to remove the old one i used a 22mm deep socket after having cut the wire.

next i removed the exaust heat sheild and screwed in the new sensor by hand. because i had removed the heat sheild i could now get in with a 22mm spaner, allowing my to tighten up to the max.

this should help with the dicky starting problem IF (and olny if) the sensor is the problem,.

one more thing - i forgot to plug the sensor back in on mine, and travelled 130 miles like this, and idled, and even did a cold start this morning before i noticed. the only give away to the plug being off was the engine management light, it ran & idled fine, if losing a LITTLE power. That was disconnected, so reading the wrong air should only effect performance / fuel consumption, not cause it to fail.

could be your timing belt. easiest way to check is pull the dizzy off, if the rotor doesn't turn when you crank the car, then you timing belt has snapped or is slipping. if this is the case, then you have some MAJOR problems, and WILL need to be towed. possibly a head swap needed, but don't panick now, check it out first, like a said i could be wrong.

 

It's probably your ignitor.

 

i have the exact same problem, the problem lies somewhere in the dizzy. i just bought a whole new one and hopefully that should work.

what is this about flipping it 180?

when you put the new dizzy on, the timing has to be either right or 180 degrees off because of the notches in the cam shaft. so if at first it doesn't start just pull the dizzy back of and turn the little post that goes into the eng 180degrees around and stick it back on and try it again.

as far as timing belt goes it's not that cause i can see the timing belt bcause when i put that engine in i kinda neglected to put the timing belt cover on.

it's now at the shop. i figure that now the mechanic can do it and it'll prolly take him about ten minutes to find out the prob (since i'm a moron anyways) and i won't have to mess with it out in the cold. so yes i've given up and asked for help. (no offense to all you guys but i'm sure it's hard to tell me what's wrong without the car there in front of you)

i will post what the problem was though and how stupid i feel when i here it's something i should have known. but you guys have been a great help though i hope this thread can help someone else in the future.

Screw that holds your rotor on in the dizzy fell out.....my thought

 

check your starter too

i have a z6 that i just rebuilt. put the engine in the car prime it, everything is cool, start it up, starts than immediatly dies check for spark using my helms manual, turns out i had a bad ignitor after it started the car like two or three times. replaced it good to go.

if its not that, check the ignition coil

 

ok i guess i just wasn't sure what he meant by "ignitor" so that does sound like it could be the culprit.

i took off the cap, so theoretically if the cap is removed and the rotor isn't fastened properly the rotor would fall out or at least be loose. neither of these is the case- it didn't fall out and it didn't move when i checked it.

should have the verdict tommorow. srry but i caved and took it to the mechanic. i'm still surprised at how relieved i am that it's out of my hands. i remmember going to cali this summer with a non running car at home in the driveway and i was worrying about why it wouldn't start way more than i should have been. it took away from my vacation.

now though i mostly just want to know what it was and how i could have know. just in case it happens again.

if nothing else now it's here on h-t so it can be of help to myself or someone else later on.

 

I bet one of the wires came loose on the ignitor. This left me stranded in the turn lane one day.
Towed the car home and tightened the spade connectors. 15 minutes later it was running again.

 

it was a problem in the dizzy so i had to get a new one. i'm planning on sending this one back but i'll check the ignitor wires b4 i do that
