16v not starting - Saxperience

Mickswan · 30th October 2014, 11:58

Another thread on this as I've searched and read a few but I'm not going to bump an old one.

So dropped the engine in and everything's hooked up, when I crank it I'm not getting a spark.

Fuel is getting to the rail and injectors ok

Immobiliser is not causing any problems as far as I can tell. I took the barrel, immobiliser, ECU etc from the donor car so it's all matching.

The only things I can think of are the crack sensor, dead coil pack or earths.

For the earths I have the two coming off the battery, one going to the chassis and the other going to the back of the gearbox. The Earth from the loom is attached to the top of the box.

I've read that some have ran two earths to the chassis and had success, anyone comment on this?

I'll replace the crank sensor along with cool pack to be sure, but does anyone have ideas what else I should look at?

try the crank sensor first. I had this and the plug was very grimy inside so thus not making contact

Ross^p · 30th October 2014, 14:12

are you getting 12v to the coilpack?

Mickswan · 30th October 2014, 17:09

To be fair I think the crank sensor will need swapped at the very least cleaned as the engine had a massive oil leak before I done the top end.

Ross, sorry electrics are not my strong point. How would I measure this with the multi meter? As in what wires do I probe?

Take the plug off, ground the black probe of your meter and check the the wires with your ignition on and the red probe of the meter.

Correct?

stevo67 · 31st October 2014, 21:39

Give the wires a wiggle on the ones going to the crank sensor,sometimes you get a break in the wires.

Sorry stevo thought I'd typed fuel correct as in the correct way around on the rail.

So I've just been out with the multi meter, started by checking the battery and getting good results so not the battery.

Checked the coil pack plug, grounded the probe and I'm only getting 0.07 volts. So obvious problem there. As I'm shit with electrics where to now?

Pick of the dash lights so no immobiliser problems.

Strip down the coilpack wire and check for any breaks, it's likely a wire is broken whilst the engine and loom has all been moved around.

Mickswan · 1st November 2014, 16:44

As I proble the plug there's four connectors, which one or ones should I get 12v from?

Mickswan · 2nd November 2014, 15:26

Ok, I tried a known working unlocked ECU and still exactly the same. I've checked the earths and they all seem ok.

Earths are correct at battery to gearbox, battery to chassis and loom to gearbox?

Got a new coil pack coming tomorrow so I'll try that as soon as it turns up. If I get no joy with that I'll replace the crank sensor.

Can someone confirm I have the fuel and return the correct way around as pictured earlier in the thread?

Mickswan · 2nd November 2014, 15:34

To add when I do crank it over it sounds like it's going to go, a cough and a splutter and nothing.

Mickswan · 8th November 2014, 12:59

So I've just put a new coil pack and crank sensor on and still she refuses to start, actually sounds like she's going to go but nothing.

Tried a known working unlocked ECU and it's the same so I know it's not that, also used different battery.

Really starting to piss me off but I'll persevere.

Any suggestions?

Prickle^p · 8th November 2014, 13:04

Mine sounded similar about year/half back. Randomly the car just stopped running. After tearing my hair out it ended up being 1 injector and fuel pump. It was turning over slightly, just like yours but it wouldnt run. Once i changed the injectors and got the codes cleared up off the ECU it fired straight up.

Just to check, does the above work fine?

Mickswan · 8th November 2014, 13:16

I've just had the fuel line off the injector rail and when I turned the ignition on I filled a bottle pretty quick so I know the pump is working fine.

I was going to check for and clear and codes but the piece of shit reader I got lights up when you plug it in but no start up menu so I guess that's fucked. Have to source another from some where, wouldn't care but Muz offered me his when I was at his during the week and I said is alright I have one. Sod's law!!

As said I'll get another reader from someone and have a check, then injectors will be my next port of call.

Mickswan · 8th November 2014, 13:44

Just had a think and poured some fuel into the bores, tried firing it up and it went for that fraction of a second. So my conclusion is I've got dead injectors, so I'll need to find some and touch wood.

Obviously will tae the fuel line out tomorrow and see which are at fault.

Gandi699 · 8th November 2014, 16:46

Pull the Rail and see if they quite into a box or some cardboard on cranking. I had the same problem, one dead injector and it wouldn't start even though it should have ran on 3 but ran on easy start. Swapped it for a known good one and fired up first go

That's what I'm hoping there's a injector cleaning place near me so I'll test them tomorrow and get them up to have the ultra sonic jazz done.

Mickswan · 15th November 2014, 11:30

Ok, had the injectors done and still exactly the same. Proper pissed off now, I'm back to the no spark theory.

I was sure it was trying to go when I dropped fuel in the bores, but now I'm thinking that it could have just been the fuel compressing before it was dumped out the manifold.

Can someone run me through testing the plugs when they're out.

Also should probably get a code reader on it to clear any codes.
