hello boys & girls

drove car yesterday, it has been sat for a week run perfect before, driving to the fuel staition yesterday & it started to missfire now & then got to the garage & it just dyed on me started it up again ok then dyed again i thought here we go more hassel, managed to get it going again flew out the garage to get home quick got to the end of my road & that was it dyed completly. got it on the drive would not fire at all stunk of fuel
today i rooted through the dash to find one wire broken to the ecu green wire pin 4 solderd it back togeather still wont start went to the boot to look at the nock sensor in the boot & its melted cut it off & joined wires togeather still wont start, what would cause this sensor to melt.

thanks anyone alan 1990 2wd saph

 

No idea mate, never heard of that sensor melting before.

 

change the coolant temp sensor

 

ok sir thank you i will give it a try & hope & pray. must start somewere.

 

I should put mine money on the TDP/REV sensor or the Phase sensor because of the misfiring.

I did had the same running well.....running well....running well....misfiring.....running well....misfiring and dyed.

And will not start again, umless you lett it cool down.

I changed those sensors and the problem is solved

 

odering coolant temp sensor 2day i will also see how much them bits are you advised as well i did notice the rev counter was going funny as well

thanks i will let you now soon as i get the bits & put them on alan.

 

ahhhh this ugly problem rares its head again mine does it a different way lol runs fine for days then all of a sudden runing fine dies then as soon as its died its running fine again can do this for a day or 2 then its fine again how the hell do u find a problem like that????????? good luck mate hope u sort it lets us know an ill try wot uve done

 

There you go

 

still waiting for parts to be delivered hopefully there be here 2day

 

got the bits iam fitting them in the morning i hope it starts after but i still aint 100% its going to. phase sensor , coolant temp & front pully sensor.

 

fitted parts today still wont fire

 

went out today to have a look at wireing thought i will just see if it starts & guess what it started let it warm up went to the shop drove back home no problem put it back on the drive & yes it dyed again & will not fire up at all strange will get there in the end

 

when it dosnt start does it have a spark is first check i would do..has map sensor gone tits up disconnect it and see what happens ive had a few like that in the past

 

Did you already replaced the TDP/REV sensor ??

 

yes fitted new front pulley sensor gaped at 1mm +s fitted coolant temp sensor +s new phase sensor in dizzy gapped at 0.2mm bloody thing i wouldnt mind so much if i hadent just spent over 4and half grand on new engine. ........... i got power to all the sensors and coil and dizzy but have no spark to plugs.injectors are working fuel pump goes i will check that map sensor 2moro i think i will just order one to eliminate it piece of mind kind of thing plus get new rotor arm & cap then see what happens laters chaps..

thank alan.

 

what about ignition amp on the inner wing. may be worth giving this a try as if it isnt working there wont be a visable spark.

 

had me mate round today with his saph tried his 3 bar map sensor still wouldnt run then tried his ignition amp still didnt go so then cheaked the timing and found the dizzy and bottom pulley didnt line up to where they should be. cams line up spot on it looks to be about 2 teath out on both pulleys wich is very strange cus now and then it will run perfect no knocking or anything will remove bottom pulley 2moro and get it all lined up then see what happens dizzy bearing in sharft feels a bit dodgy with a fair bit of wear in it. god nows why they are out of line new belt tensioner the lot belt is not slack at all.

laters chaps thanks

let u now what happens al

 

you don't need to remove the bottom pulley to get the timing correct. also i'd reduce the crank sensor gap to around 0.6mm

 

i couldnt get the bottom pully off any way so done it wiyh it on timing is spot on i will try the front pully sensor 2moro at 0.6 & see.


thanks al.

 

Thank you every one for the info ive now got it going again found 2 wires makeing and breaking in the wiring loom on the n/s of the bulkhead soldered them and heat shrunk then turned the key and away she went thank god for that.

thanks again guys alan..

 

Don't you just love cars

Im happy you got it going at last

Steve.

 

hi
Looks like the old problem , the "eart" wire is going bad and the "curent" is going throu ECU and other parts . The nex is clutch wire / gas wire going hot ...
