Put a different rad in my low boost 6 yesterday, bled coolant out this morning and ran till warm etc did a few other little bits and bobs to it like pulled off the quickshift and changed the rear lights, swapped the bonnet from another car etc.

Left the car while I fitted a new steering rack to a mates car and after he had gone I went to drive mine out the workshop to give it a bath and it just cranked and cranked and eventually backfired massively..... Deff getting fuel then!

Fuel pump primes ok, injectors are firing as it backfires and plugs are wet, trie earthing out a plug and a coil to the head and no spark.....

Also to be safe I've checked the cam belt is fine and done a compression test as I never have on this engine since I put it in

1, 200 psi
2, 205 psi
3, 207 psi
4, 198 psi

So all good.

I've checked every fuse on the car for continuity and all are fine,

Pulled the plug off the crank sensor and found a corroded pin. Cleaned that up still no spark....

Does the crank sensor give the ecu a pulse that shows when to spark?

Fooked crank sensor? Got a spare cam sensor here so will try that in a min but otherwise I'm stumped.

Havnt really touched any wiring since it had been running.

12v while cranking? Will check in a sec. Fuel pump relay or another one that controls spark? Fuel pump one was brand new about 3 months ago also tried the old one (as nothing was wron with it) and still no spark

Gonna try a code read on PP2000 in a sec but doubt it will show much

sounds like relay is good then, but ecu isn't switching the power on when cranking, so likely to be the crank sensor I would imagine, I take it being a lynx ecu it is not able to be locked?

The multi relay also controls several power feeds to the ecu I think so may be worth a tap on it incase one of the relays is sticking!

yup it'll work.

So did PP connect to the ECU successfully? If so, that ecu is getting all the power it needs so that's ok.

Another vote for the crank sensor.

I know you said you've checked all the fuses, but just wanted to make sure, is the interior clock and mileage display working correctly, including the central locking?

And if the crank sensor doesn't cure it then I'm pretty stumped other than checking every inch of wiring loom and every connection.

Was promising to see no RPM reading on pug planet but most cars don't give data while cranking. The battery voltage did show the whole time though so it was streaming that while cranking.

Every earth on the car was cleaned thoroughly a couple of years back when I out the new engine in but the car sits for half the year so I'll bridge one across tomorrow.

I already gave both the inner wing connectors a good wiggle this eve but plan is if crank sensor doesn't cure then they will both be apart and inspected for corrosion etc.

And yeh got autodata at work which has resistance checks on but they are never that accurate.

In my years at Mitsubishi I had several occasions where resistance checks on sensors or electronically controlled diesel fuel pumps were both showing to be miles out of spec according to te tolerances stated in the workshop manuals or autodata and yet when the new one turns up it's just as far out and didn't cure the problem lol.

Had a look earlier and the hdi has the later type 2 pin rounded square plug crank sensor.... Mine being a 1997 phase 2 has the 3 pin rectangular brown plug on a lead gonna have to order one in from pug tomorrow morning as I'm pretty sure I Havnt got one kicking around at work..... Boss won't be happy my cars sea in the workshop tomorrow lol oh well

Edit: I say that but just had a good rummage in the random parts trays on the walls and found a brand new one haha. Will try it in a sec fingers crossed!!

Fitted the f**ker and started on the button so chuffed to bits

So yeh if you get fuel and fuel pump priming but no spark then crank sensor is at fault! Worth remembering cheers for the input guys

Yes mate looking forward to it now, they send the tickets out this week I've got 8 runs booked and will probably buy more on the day. Even if something went wrong with the 6 I'd still turn up in the Leon TDI and show ya all how a diesel should go lol. Handles like s**te tho

If I had found the one we had at work sooner would have had the bloody thing sorted but never mind. First time my 6 has ever let me down in 6-7 years of ownership an was the original sensor so can't grumble really.
