Default 16v 230 won’t start?

Hi all. I’ve got the B230 16v conversion in the car and trying to start. Problem is, it’s firing but won’t catch?
Ign timing is with TTV flywheel having blank holes in starter motor hole at no.1 TDC.Valve timing is as per the book with crank at TDC no.1 and both cam wheels lined up with marks on cam cover, had to spring the exhaust via pulley bolt to keep it upright however. All lines up after rotating so seems ok.
When cranking it shoots blue/purple flame from each exhaust port but won’t attempt to “fire” either with petrol or a squirt of easystart.
What d’ya reckons up? Getting pissed off with it now.

Completely rebuilt 8v into 16v, this is first start. Fuels about 7 months old but a squirt of easy start didn’t alter anything nor did some new fuel squirted into throttle body. Just checked valve timing whilst turning over by hand and rod in plug hole to observe tdi/bdc and all looked to be in right order. Rotor pointing at no1 lead at tdc
Just fires a big purple flame with no attempt to “fire” or “catch”

If your timing is correct, I hope you did install the flywheel 180 out. Please don't ask me how I know.

that would cause said issue. I would double check that if everything else checks out good. If that is ok, could be possible EZK or ECU issue.

I'm pretty sure the distributor can be installed 180 degrees out.

Just tried flywheel 180 dog out, same. In starter motor hole, same. Either side of starter motor
, same.
If I put distributor 180 deg out there is a spare screw hole at top

spark plug leads swapped? makes for a rough running engine, or not running.

Has the flywheel or distributor ever been removed? If they have not it's your firing order. PM me your cell...

sorry dude.

funny thing is, I swapped leads on a 16V engine I tore down and rebuilt, years ago. I mean, can happen.

Anyways.

How did you verify timing, via the line on the crank or via measuring piston to be at TDC via spark plug hole? Just to be sure timing of cams (and thus rotor) is correct.

This a block mounted dizzy on a B230 or head mounted dizzy?

Okay let’s clarify. This was a B230 now converted to b234 + forged bits with TTV flywheel. The gearbox is off the car and I’ve tried the flywheel in 4 different positions and it does the same thing, big flames out of ports but no firing as such.

Crank position sensor in working order? What ECU EZK combo are you using? Blue flames out of each exhaust port..... Do you have the O2 sensor hooked up?

I can only assume the cps is still working fine as it’s firing each cylinder individually. ECU and EZK are chipped and were running like that perfectly a few months back, no way of telling if anything changed whilst car sat quietly in garage. O2 sensor is sitting jammed inside an exhaust port as no manifold is fitted yet.

Is it correct to have to keep the exhaust cam under tension with a wrench to get marks lined up when fitting cam belt?

Maybe just slightly... but it shouldn’t take much. Are the cams in correctly? Intake on the intake side and exhaust on the exhaust side?

I can only assume so as they were marked by the guy that sold me the head. Are the part numbers different or any identifying marks? Distributor drive is correct as far as I can tell.

I do have adjustable cam gears but currently have them at “0”. Maybe I should compare with the one stock one I have? One broke in transit.

The cams cannot be interchanged.. the one has a slot für die distributor, the other hasnt..

Could you please provide pics.. you want us to tell from miracles what your problem is... in other words.. your error documentation is ****ty...

So you checked TDC with a rod in the sparkplughole? maybe your Pulley timing is off.. so verify TDC with the marks on the beltpulley..

did you use the 16v distributor or the 8v distributor? if you used the 8v one, it doesn't align the same..

shoot ignition timing at the cam gear, those don't slip. if it's in the ball park of tdc on #1 you're good. if it's waaaaaay off (45+ degrees), you've got an issue either with the pickup or the distributor.

This is what I came in to ask. Lifters pumped up preventing the valves from fully seating. ?
