Ok, Please welcome me to Cosworth ownership!
Ok, my mate SVONY and I have been freezing our nuts off..
He replaced the water temp sensor with a new one.
we have fuel, we have spark, the car cranks, twice in the whole time it made a quick attempt to turn over. Still nothing.
we tried a spare map sensor, coil, amp. Fuses in the box next to the battery are good. The last time the car was on was last Wedsneday. I just turned it on to back it up and then turned it off, that's it. Help what's missing!!! What about the ECU?? he has a spare L8, I have a L6 in it right now (3dr) any help will be greatly appreciated

BTTT ...

Fastmaul

after several tries, we took out the plugs we could smell the fuel on them and they were a little wet. Dried and cleaned them and put them back in.

EscortWRC

And.........

(did it start??)

Fastmaul

LOL, if it did I wouldn't be posting this!
so that's a no

svony

Nope, just cranks but would not turn over . I swapped my coil, map sensor and ignition ampThings I did not check, crank sensor and phase sensor, was not sure how to check these (outside of replacing them). I had a similar problem with my car and it turned out to be the ECU, will my L8 work in his car...

Don't you guys ever sleep...

It might be worth cleanig the crank sensor as these cause loads of problems, or alternatively change it, as for phase sensor i have no idea.

Nope just finished work

Fastmaul

Svony, EscortWRC is in Seattle! check his avatar

Fastmaul

Gav, stupid question..how do I clean it?? just wipe it down?? do i need to disconnect it? it's a new sensor not more than 5 months old.

Gav Diamond

iTrader: (6)

All i used to do was wipe it over with either brake cleaner or WD40, i think you may need to undo it off the car to clean it, cant remember as mine has had no engine for 18 months

EscortWRC

Its just now 8:00pm here.....LOL

Fastmaul

Thanks dude, I would try that now but it's freezing outside, will have to try that tomorrow

EscortWRC, my kids love your avatar

Erik, I did a search and came up with fuel pressure regulator as a possiblity (especially since there was a strong scent of fuel). My injectors worked fine maybe we can swap those in, also I guess we will have to take the dizzy cap off and examine the rotor and phase sensor.
Gav, I wiped the crank sensor as clean as I could, will try again with better lighting...

Later all, gotta get some sleep...

Fastmaul

Cheers

Well, it was almost 60 degrees here today and reasonably sunny.....guess you're on the wrong coast

LOL

L6 ecu's are notorious for burning the earth on the board where the multiplug is soldered. check that.

RichardPON

Have you tested for a spark in the normal way? Check each lead?

Had similar before where the rotor arm was burnt out, and it didn't want to know apart from the odd cough here and there.

gearboxman

Did Svony replace the temp sensor in an effort to cure this non starting, or, has this situation occurred since temp sensor replaced for some other reason?

Alvyn

when he pulled the plug of the temp sensor check that the wires have NOT been pulled through the plug so they are NOT making a connection on the new sensor now

Uncle Henry

My bet is that its flooded. Running a car for a few seconds from cold (any car - even a brand new one) will leave it very prone to flooding. best bet is to throw a new set in (any that fit will do, its only to get it started) failing that, cook em with a blow torch then try again.
It may also be that the ignition system isnt 100% and giving a weak spark, thus adding to the flooding issue, check/replace cap/arm etc etc.

if it aint that...fuck knows! lol

Gra

have you checked the ecu connector? may seem stupid, but mine came just a littel off and puzzled us for a while,

Fastmaul

I'm guessing I need to take out the ECU and open it up? will the L8 work (just as a temp?)

Paul Eggleton

As bernie suggested, if you have changed the temp sensor, could this not be the cause of the fault?

Fastmaul

Yes checked for spark each lead had one. (grrr if it's the rotor arm, I got it not to long ago. LOL)


No car was running fine couple of days ago. If anything the idle was hunting when cold, I read here that it most likely would be the water temp sensor. Once the car didn't start the first thing to
be changed was the sensor, but nothing happend.


Even before He changed the sensor it felt a little loose, but nothing major?

Are you talking about the plugs?? the cap,rotor, sensors have been replaced June of 04 but the car has really only been driven in the last couple of months. Oh, BTW I have some cool video of your car, and Pictures! I was with the former owner when he bought it


Would I just unplug it and re plug it back in?? wiggle it?? burn the car??

Fastmaul

Any one else??

Alvyn

Eric, go and check those 2 wires in the plug again and make SURE they are actually making a connection with the temp sensor

Fastmaul

Thanks Alvyn I'll have to try that again when I go home since I'm at work right now. I hate that i'm 5 hours back from you guys for things like this!!
So would a bad connection not let the car start?? what about before the sensor was changed??

Rhys

Doh, nightmate mate!!! but as said if ur getting spark on fuel etc its somthing to do with the ECU/sensors.

Hope u get it fixed soon dude!!! Looks like your honeymoney period with the car has finished

Fastmaul

I know right Rhys!! I was in Bliss...
I guess the cossie honeymoon is over, comence the marriage!
so will the L8 work??

noodlesblacksaff

had the same prob with mine ended up being the ignition moudule/amplifier on the n/s/f inner wing

Fastmaul

I tried a different one, no change.

yes to your 1st Q and MAYBE b4 u changed the sensor the wires inside were fine!

l8 ecu will work but you have to change the 2 outer wires round and use a 4x4 tps for it to work correctly

Fastmaul

Thanks dude, I have some stuff to try when I get home, thanks for any help.

I though I would get more help from other people though to be honest.

Rene

check if the chip is in ok as i had a problem with 1 of the legs not connected properly and had the same shite

Fastmaul

I'm going to have to open the ECU, I don't even think it's chipped!!??

Rene

std L6 then ? might worth to have a look but that's was my problem when i fitted a new one

Fastmaul

I think so Rene, I'll check when I get home, still at work. it's only 3pm (or as you guys say.. 15:00) in the afternoon.

Rene

good luck mate

Fastmaul

No luck, the car is parked outside, but by the time i get home it's dark and cold.
Thanks though, I'm going to have another crack on Saturday morning. I think the car knows that I'm getting another engine getting built with stand alone ecu. I think it's rushing me!
Ok, well it's going to have to be put in the garage and when it comes out, it should be a little bit better. I just wanted to drive it a little bit longer.
