XE Conversion rewired - Running now but has terrible running problem

[VR4AWD]

I think this is the place to post but not sure ?

Right after a couple of more days on it, there is still a running problem after some help from the topic below.

Its had new plugs and new temp sensor along with the new properly installed wiring loom for the engine.

The car still overfuels terrible and can smell the petrol from the exhaust, after 2 mins of running you remove the plugs and there all black and sooted up.

When you rev the car it dips in power and hesitates before a huge backfire and a huge flame pops out of the exhaust before able to rev it.

Iv gone over all the wiring and thats correct aswell as all earths are connected so im stumped on this now, and not sure where to go with on this now.

Can anybody point me in a direction that it might be as there is no diagnostic socket on the wiring .
Im unsure how to wire one in from guides, can anybody point me in the right direction to this.

Also running voltages for

MAF Sensor & wiring.
Air temp sensor & wiring (small sensor in intake pipe).
Throttle position sensor & wiring.
Cam angle sensor & wiring.
Crank sensor & wiring.

is the eml light connected to the dash?

Im unsure as its had a digidash conversion and thats just as bad as the engine wiring was.

rev counter does not work for a start and from memory i cant remember any EML light light up when i power up the dash dials.

may not have a eml light on the dash some mk2 astras had them in the center of the dash on a seperate instrument panel

have you checked the vacum on the fuel reg??

it has an aftermarket fuel pressure regulator on it so not sure how to check that, plus im not 100% sure on checking the vacum on a standard or aftermarket unit

[autoworksnovasport]

you can get a gauge from ebay that will screw straight on the side of an aftermarket one it should be 3bar on idle
