Fiat Seicento 900 Starter Issues: New Battery, Fuses, Candles, Fuel Injection - Still Won't Start

Hello, I have a problem with my Seicento a month ago, he did not spin the starter, I pulled out, I checked the good one. I fired it a dozen times out of pride and it went, surprisingly, I found that the battery was dead, on the same day I went and bought a new one, I put it in and it went the first time. After driving 3km on a new battery, I left it for 3 hours at home and so far I do not want to start it, it's been about a week. The car spins, but won't start.

I checked the fuses, replaced the candles, added fuel directly to the injection and nothing, although after refilling it started to spin more vigorously. I have no idea what to do next.

Start by checking the spark.

The "key" code light goes out? After switching on the ignition, you hear the fuel pump for 3 seconds? the "carrot" injection light comes on?

Check what is missing spark or fuel. When the candles are dry, there is no fuel, when wet there is no spark.

I did not check the sparks, because when I took off the hose and turned it (to get some fuel and thus check immediately if there is fuel injection), it spilled a bit, so I did not risk it. When I added 1/6 glass of fuel to the injection, when it was on the revs, it started to work better, after removing the candles 2 were wet, but that's probably because I added it.

Oh, and as for the pump, when the car was still starting normally, the pump started (or pumped fuel) for hmm .. 2-3 sec, now it takes much longer 4-5 sec, overall it's a difference, but I don't think so sure it was the pump's fault when I added fuel directly to the throttle.

Of course, I will check the spark as soon as this fuel evaporates

The CODE is on all the time, but I don't pay attention to it, because with this code I've been driving for several weeks, if not months. Injection control lights up.

It was raining and it was completely down.
But you still have to check the spark and the fuel pressure.

I'll check the spark today.

As for the fuel pressure, can it be checked without a pressure gauge?



I have one more question, should I see the fuel on the throttle when I turn the starter? (is fuel flowing in general)


EDITED: Mute spark (checked on 2 sets of candles)

So what ? For scrap .. ?

Why scrap it right away? You checked what you could, now you have to bring it to the workshop, let a specialist evaluate the repair

Because the repair will consume 50% of the car's value.

Perhaps it is, perhaps not, but look at it from another angle: how much will you get in the scrap? from PLN 500. For something fit for driving you have to spend about 2k PLN, plus the costs of registration, insurance, etc. If this sc, apart from "giving up smoking", is technically efficient, the repair may be economically justified

Hello, mawerikzDG, in these Fiats, the shaft position sensor is almost a standard, and even when you are proud, you will be sure, replace this sensor.

Yes, but the sensor was recently replaced, i.e. from a year ago, well, it does not smoke. When he first zpierniczył, he smoked pride, but could the shaft position sensor break down by firing on pride?

No, he couldn't break this
You can do such an attempt: under the rear seat on the right side of the car there is a lid, under which you will gain access to the fuel tank, dragon and pump. remove the plug and connect the bulb to the two thickest cables (black with purple and white, as far as I remember correctly), after turning on the ignition it should light up for 3 seconds and go out, if it lights up when turning the starter, it means that the controller "reads "engine revolutions and starts the pump, so it's not a shaft sensor

The fuel is evidently pumping under a lot of pressure, when I remove the hose at the injection, so the pump works, but I have not seen fuel from the injection go out.
