88' vert w/S5 T2 won't start
I have little bit of problem with S5 Jspec T2 swap.
Did search when was at work and couldn't find solution.
My stock NA motor was running no problem.
We've installed S5 JSPEC T2 into my 88' S4 Convertible. We used S4 harness.
I'm gonna run Premix so we left S5 front cover on - but disconnected wires.
Here is what I'm concerned about:
1. It won't start.
S5 injectors - S5 plugs spliced into S4 harness.
Spark - OK
Fuel pump works
Fuel lines connected properly
It cranks but seems like gets no fuel into cylinders.
We've tried easy start spray (don't remember the brand) and it tries to fire but than again no fuel from fuel rails.
Does it sound like injectors?
2. Some of my plugs on left engine harness - the one for charging system, starter and stuff - were gone.
What sensors do I need connected to this harness and what are the wire colors?
3. Would not running KNOCK SENSOR be a problem too?
THANK YOU

I'll try the plugs later. In my understanding if they are wet means injectors are working or stuck open. If they are dry injectors not working.
What is the correct way of checking injectors without removing them? I've Ohmed them at ECU plug - each injector with ground in the plug, and they were all readind over 500 Ohms each.
