Technical Crank, No Start; Smoke from spark plug holes; need help

[koalar]

Thank you so much — I’ll do what I can and see what happens

Won’t be up to too much this evening just with the light and work

Just got a multimeter though and am ready to go down the fuel system troubleshooting pipeline!

I'd start by getting some of the fuel out and testing it

Remove this plastic cap

Carefully push the pin down with a small screwdriver or similar, cover with a rag

Get someone to switch the ignition on

Does it smell of petrol, diesel or varnish

Hello!-– I’m finally able to work on the car, end up captured fuel from the fuel line. I bet the bullet and just wiggles the rubber line off


I don’t personally know the difference is and smell between diesel and petrol, however, I do know that this one feels may be more oily and isn’t evaporating off my skin


I’m beginning to wonder if my mechanic accidentally gave me a Jerry candle full of diesel like someone else suggested earlier

I do have a multimeter on me and can proceed to start testing my injectors if that sounds like a smart step

The above picture is what I was able to capture when the fuel pump was priming from the on position

Diesel is difficult to ignite with a match.
Gasoline ignites immediately and burns your hand.

Pouring gasoline on a cardboard will create a sudden huge flamme which won't persist. The fire might even go out and leave most of the cardboard intact.

Pouring diesel on a cardboard is still difficult to ignite. Once it burns, it will do so for a long time, steadily, and it will eat up all the cardboard and even stuff under it.

I don't suggest you try any of these!

Also, if you put diesel on a stone on the ground and walk on it, your shoes will slip, and they will keep sliping for the next 20 m even on a clean surface. Diesel drivers sometimes use plastic gloves because the pump dispenser is so messy and oily

I'm convinced it's diesel, as already mentioned above.

For reasons…

I’m beginning to think diesel

Thank you so much for your input

I am still very much looking for further troubleshooting advice or next steps if anyone has wisdom for this situation — cannot stress how grateful I am


I feel like I’m looking at injector cleaning at minimum, to full fuel system flush at maximum

 

[Keepthe12alive]

Actually now I can’t tell

I poured some into a ceramic coffee cup and it lit easily — safety precautions of course

Different light

Theres a likely chance you could pump out most of what you have in the tank and put about 3 gallons of fresh high grade petrol in to dilute the balance of diesel, a clean of your fuel rail should cope with the diesel debris. Not sure how the injectors will cope though but i did buy a set through amazon at a very reasonable cost about 4 years back.

All in all dont forget the diesel debris in your engine and exhaust will smoke for ages.

Did the mechanic who gave you the diesel think you had a diesel car?

Most fresh petrol is blue here in the UK

Diesel is clear or yellow

Old stale petrol is yellow and smells of varnish

Doesn't look like usable petrol in the photo

here’s another picture — mind my headlamp is pointed right at it so it might’ve altered the lighting a little

Since I know what I would need to do if I suspect the fuel itself is either contaminated or not proper petrol, could someone help me formulate an idea of what I would do if it turns out it is proper petrol?

If I assume for the sake of argument right now that it is proper petrol, I would imagine I would come back tomorrow and take off the fuel rail and test the injectors with multimeter, and then try to clean them with carb and a 9 V battery

After that, I’d imagine testing components in the fuel pump assembly with a multimeter

Cranking, it did sound a little different today, but it could just be because of the weather change and that it’s a little tired

I know I could try to have an assistant with jump leads to try each individual spark plug one by one

And I know I could try having my battery fully charged

I’ve also asked a friend of mine if they’d be willing to bring a Jerry can full with fresh petrol so I could potentially attempt the semi-flush offered above

Diesel

Petrol

Petrol has a blueish tint

Although looking at Eric the car guy video his are the other way round, USA or brand I guess

 

[koalar]

Diesel in a petrol does not cause any problems long term, normally

 

[Zardo]

a mixture of the two ignites more readily than pure diesel and burns longer than pure gasoline, and the color is in between the two
but if it has an oily touch to it which stays on the finger for a long time then it's diesel
also if a small volume of the mixture is poured onto a plate, the gasoline part will evaporate but the diesel part will remain and make the plate an oily dish

No really need for that. Diesel didn't do any damage. It just doesn't fire up on the petrol engine. The best you can do is to get out all you have in the tank. I think that if you disconnect the ECU contacts and put the ignition on, the fuel pump goes on without stopping, so that's an easy way to get it out. Just pay attention to the level and turn the pump off immediately, as soon as it got all diesel out, so it wouldn't run dry. Because running the fuel pump dry overheats it and that can cause damage to itself (to the pump).
This is my diesel picture.

Missed this post

Must be petol

Petrol and diesel mix will still light readily as it has petrol in it.

I’m still stuck—I had another four can of premium petrol, there’s a chance I didn’t completely bleed it out, and I feel really stupid because of that, but I bled it till empty and I filled an empty Jerry can

It started to turn over a little bit when I first tried it, but now it just won’t get above 300 RPM

I think I’ve killed the battery now
