Technical 899CC Sei SPI Won't Start

[tduknet]

Hiya all,

My mums Sei SPI 899CC W reg won't start, T P Dubs has been out and thinks it could be the crank sensor?
Car has been parked up for a week before I went to use it, Drove fine before hand.
I have done a few videos with some info on it.
centojosh any thoughts?

Anyone local to Plymouth have a spare SPI Crank sensor I Could try? before mum goes to buy one.

The crank sensor on my 1108 MPI went a few months back and it kepy cutting out, but this won't even start.....

Attempt 1 Engine Bay -

I would have to agree with crank sensor too. Afraid I've got no spares though all my fiat engines are either carb'd or MPI.
Sorry for the late reply, was out with no signal

Cheers buddy, no worries I'm still out and about waiting for the other half to finish work mum will just have to order one Friday and see if it works.

Thanks for looking

I'd pop a couple of spark plugs out (one from each coil will do) and check if they are sparking (with the crank sensor connected of course), if they aren't on either coil then it's about 90% likely to be the crank sensor.

Hi buddy,

Checked Spark on each coil pack when T P Dubs came out spark from both coil packs.

That rules out crank sensor.

Is it getting fuel past the injector? You should see it dribbling onto the throttle butterfly (remove the "bob") when the engine is cranked.

 

[T P Dubs]

a tiny little dribble, ive got a known good injector now to try in it as long as its the same as the 1.1 spi injectors (anyone know if there the same?) computer is reading an injection signal but it doesnt look like enuf fuel coming out to me

 

[fingers99]

It isn't the injector, then. Tiny dribble sounds right.

Spark from coils, but check for spark from plugs..........

Not enough fuel for cold start? Try squirting a little fuel down TB while cranking. Keep your head out of the way!

If it coughs into life, possible duff coolant temp sensor (blue coded).

When cranking with crank sensor plugged in you can hear a pop ( sounds like unburnt fuel ) igniting in the exhaust and when the bob was off it hissed back through there at the same time, the car won't even start with bumping it either.

 

[tduknet]

Could the timing be out? But car was running ok before it was parked up for a week.

Is the 899 a non-interference engine like the 1108?

 

[fingers99]

Doubt the timing has slipped -- it's by chain.

But it's a prehistoric pushrod engine with hydraulic valve gear. Compression test (dry and wet) should show which cylinder(s) are problematic.

I had an 899. Had to remove the crank sensor for some work. When I put it back in I just pushed it into the holder and didnt bolt it up. I got the same symptoms (exact) that you are getting - trying to start but not quite managing it. After much wasted time I correctly bolted it up and it started immediately.

Clearly the gap to the teeth on the pulley was my issue. You maybe shouldn't rule
out that your sensor is partly faulty rather than dead.

Hope that helps, good luck with it

Friday will be the day I will find out.

 

[blu73]

If there is either spark or fuel that rules out the crank sensor - if it was the fault you would have neither.

By all means try a different one but don't hold your breath, i would do dry and wet compression test as suggested already

 

[tduknet]

Hi all,

Fitted brand new crank sensor before I was going to get my hands on a compression tester and hey presto she came to life with a cloud of smoke from the exhaust driven about 95 miles since Friday ( when I fitted new sensor ) and seems fine again. Is it worth me still doing a compression test ?

Cheers

[fingers99]

It's a good thing to have -- a compression tester -- tells you more about the state of your engine than anything else available to mere mortals.

But if it's running OK, it's a luxury now.

On a different subject of the SPI currently my mums fuel guage is being really strange, turn right guage goes down, turn left it goes up move off from a stop / when moving guage goes lower, however if you brake to slow guage goes up, this normal as when we put £10 in the tank it goes just over 1/4 tank (128.9 pl roughly) filling from near bottom of red on guage and will do about 50-60 miles before back to bottom of red. Is this about correct for these?

My 1.1 mpi sei does around 70 miles if I drive sensible on the same amount of fuel.

Cheers

Martyn

( also to add my mums sei's exhaust doesn't have a middle box as the previous owner removed it but has the full back box )

Sorry for all the questions recently with this and other posts! Will donate to forum when I get paid.

that sounds pretty normal for a cento fuel gauge to me, they rarely stay still - you get used to it. On the flat and going straight is the only time it tells you how much fuel you have when you are driving lol.

The speedo's are pretty rubbish i find, if you want to work out mpg figures fill the car up until the nozzle clicks first time, measure distance covered on satnav until it needs fuel again. Then fill up the same way as before and note down the volume of fuel you just put in and the distance off the satnav - and calculate the mpg from that. Sei speedo's aren't as bad as cinq ones tbf but they are still a bit rubbish.
