Hey guys, have this problema for a while and I spend to much on this little car, so now I need some knowlegde from you.

My car started to over fuel, it would do 100km (I'm from Portugal so here we use metric system) and waste 14 litres of petrol, way too much from the original consumes. I bought the car doing this allready. What I did since I bought it was head skim and the seal, new coils cuz it was missfiring, new leads, new engine mounts, new handbreak system, new valves. But stik, when the engine is cold sometimes it wont start, at all. I have to force it to start by flooring my foot on the gas, turning the key and it will slowly rise from 0rpm to 1000rpm and then I have to keep my foot on the pedal just to keep the engine alive. Aafter that, engine get worm and stop doin it, but it's takin to much gas. It's consuming like 3 or 4 times what it should. I'm student, have litteraly no money and I'm startin to work at night next week, so I REALLY need the car. I read that a bad temp sensor would overfuel the car, but for the gas it's consuming, I don't think is that the issue, please help guys.
Today, I'm goin to clean the sensor on the spi that controls iddle, to see if that gets better. Gonna see aswell if the car starts whitout the injector to see if the problem is from the ecu or the injector itself. Any help would be good, thanks.

Have you checked the fuel tank is not leaking? Does the car smell like petrol at all?

Yes, I'ved checked the tank, and no, not leaking, and yes, smells like hell, whenever I turn on the car or turn off

And the smell sometimes its like dilluent

Had something like this with an spi classic mini today would run and missfire and would be running stupidly rich to the point you could smell the fuel coming out the back

After some close inspection I found the vacume pipe split to the map sensor causing all the problems so check the vacume pipe leading to the map sensor and worst case replace the map sensor

Just because of a vacuum pipe? For some reason, my car came with no intake hoses. Just a stupid mushroom like filter. Tryed to buy the original air box, but what came was only the box, when I get home I will take pictures to post. Thanks for ur reply buddy

My Sei had dark stains all over the tank but never visibly dripped or left and marks on the ground. Vacuem lines sounds good place to look

I Park my car allways in the same place, and I watched so many times for fuel leaks and nothing. Probelm with vacuum pipes is I have no idea where they come and where are they suposed to go. Ty buddy

There should be a small pipe from the back of the inlet manifold going to a black box picture included to give you an idea to where and what your looking for it

From the inlet manifold to near ecu?
In an hour and a half, I'll get home and take pictures of my engine to put out here .

How would I tell if the map sensor is broken?

Not sure how to test it could replace with a good working used one or buy a new one

Ok buddy, thank u anyway, will see that pippe.

Update buddies, the vacuum pipe seems to connected properly, in a fair condition, so, nop, not map sensor. I'm taking the car tomorrow to a mechanic. Gonna keep this updated.

Here's my webber, and, the vacuum pipe thames from the map sensor to the inlet manifold. (You can zoom in, my phone has a fair camera quality)

Update mates:
My dad told me to leave my car in our mechanic. My mechanic cleaned the fuel pump, told me my car shouldn't be always on low fuel on the tank. This morning tried to start the engine and nothing, old same thing. It won't start normally, I have to put the gas pedal to floor, to make it start. It won't just start if the engine is cold. After my engine is 90°c it will automatically work normally, but in cold conditions, and I live in an island that is tropically worm, so our temperature here is between 19°c and 27°c. It won't start normally, and I have no Idea what it could be, wasting fuel as a maniac, car goes very well on high rpm's but in lows it just tries to die. Again, checked the map sensor and vacuum pipes, all good. My last hope is to get the car in the machine to see if there's an error or something. But I can only do that on next Monday. So mates I'm desperate, I don't know what to do and I really need the car. Cheers

And my mechanic doesn't know what to do more aswell, so this is getting very bad.

Have you checked the two pole temp sender, sounds very likely that its failed.

Cheers
