S50 help

[Siggo]

Hi again
Thought I solved the problem still cutting out. Right replaced the crank & throttle sencors air metre spark plugs fuel filter. Clean earth wire s . Nothing coming up on computer. Any one please £1100 in and still not fixed

[DanThe]

How modified is it and when is it cutting out?

[Siggo]

Not modified . cuts out when driving .picked it up today was ok till about 5 min in thanks

[Siggo]

The only thing I can think of now is the coil packs

[DanThe]

cuts out when driving

You need to be more specific than that

[Siggo]

When driving and you give it gas it just cuts out and no power all dials go off but because in motion goes again. Gets worse longer you are driving it just struggles to eithen go after about 15 min

[DanThe]

If the clocks turn off (speedo and lights) then its not going to be an engine sensor

[Siggo]

I'm just doing what my machanic is telling me. Because it's cutting out that's why clocks go off.all the research I have done is saying the parts I have changed and still doing it. Only got coil packs to do now. But that should show a fault and now fault are coming up

[Brianmoooore]

What EXACTLY do you mean by "all dials go off"? Going by what you've said, this isn't even an engine related fault.

[Siggo]

Right the car will idle it's just when you excelarate about 15 min into driving it's kangaroos no power and cuts out that's when the dials go the needles bounce all over the place .i think the dial part is normal when car isn't running right

[Brianmoooore]

Which dials? Fuel gauge?? Coolant temp??
It's impossible to remotely diagnose faults without accurate and complete data.

[Siggo]

Rev counter I know for sure bounces will check other tomo when I take it out again

[Siggo]

Taken out and nothing happend .but only for 10 min.my guy thinks something geting hot then the problem happens . He Still thinks coil packs as they get hot

[Brianmoooore]

No expert on the S50, but I can't see how coil packs would affect the tacho.
If nothing shows on the fault codes, then I'd be looking for a power feed problem, and DME relay would be first thing on the list, followed by a hunt for an old immobiliser.
You don't need to fit a new relay - just use wire links to connect together 30 and anything 87 on its socket, but don't forget to remove them when parked.

[Siggo]

Is that a auto electrician job .have replaced everything else so might as well do then .cheers

[Siggo]

Is there a cheap plug in computer I can buy to check engine codes .there was a dme fault that came up weeks ago but he wiped it clean and said it must of been a old fault . Just as peace of mind so I can see for my self

[Brianmoooore]

Probably should have wrote "you don't need to fit a new relay to test it"!

A relay is a simple device, and is easily bypassed by one or two pieces of wire, depending on its type.
Just pull out the relay and fit a couple of wire links while you drive the car, removing them when you stop the engine.
If the engine behaves itself for a sufficiently long period that you're sure the fault has gone away, then get yourself a replacement relay.

[Siggo]

Googled it beleave it's the white relay I'll just buy new one. Cheers

[ross_jsy]

How about testing things before p1ssing more money down the drain?

[Siggo]

Because I don't know what I'm doing and fucking so called machanics who say yeah il fix that and 1100 later still not fixed I'm getting right pissed of .its taken me four your to build this and I just want to enjoy it now . So for a called ££ more il just replace it . Saves pissing about. Most of the car parts and relays are all new now .Christ can't be that hard to fix and yet no

[ross_jsy]

Jam a bit of wire in it like Brian suggested. If it works, buy a new relay.

Or sack your mechanic off. He sounds like nothing more than a glorified part fitter. Where are you located? Someone like Dan (DanThe) who posted in this thread should be able to sort you out if you are near

[Siggo]

Wirral area. On my 3rd machanic . There's 4 orange 2 black relays only in the fuse box 1 lime green outside. Which one is it. Taken 3 coil packs off all very easy and abit loose on the spark plug no suction is that normal.

[bobbin1982]

you sound very angry!
people here want to help you but you are being too vague
Please stop being angry and people will be more inclined to help you

[Siggo]

Not at all .pissed yes.ill get it sorted in the end.just thought il share my problems and fixes to help others. The research I have been doing lately I know everything on her. Most of it only nuts and bolts how hard can it bea˜†

[Siggo]

Checked all relays done the wire by pass still no joy. Car runs great for 5 10 min then that's when it starts. Geting worse now back firing wouldn't start. Left it for 30 min disconnect battery then it got me home

[Siggo]

Checking coil packs tomo .research saying when they get to hot they can course this problem fingers crossed

[Brianmoooore]

will check other tomo when I take it out again

So??

[Siggo]

I have a e36 2.8 will the coil packs be ok on the s50 just to check if it is them

[DanThe]

I doubt its the coils but they may fit, can't remember exactly, easy try out

[Siggo]

Just tried no don't fit. It's strange it's only when engine warm. Research saying could be coils as they get hot then wait to cool down then car goes again

[Siggo]

Pulled coils out one by one when car running see if engine note changes seen to be ok. Can smell fuel plus there's like six like little tupes above the trumpets that are sucking in air two have rubber over them so I've put screws in them

[M3Pete]

What? Can you post a picture up of your engine bay?

[Siggo]

Yeah how do you send pics thanks

[Siggo]

Still no change car goes great then it starts again 10 min in .Cluster wise manage to check while it was play up lights all stay on just the rev needle bounces

[Siggo]

Just spoke to a guy saying could be a fuel Problem check fuel tank breather or a heat soaked ecu
