And I've seen a dizzy fitted 180degrees out so it does happen.

Id check the ignition amp / dizzy => ecu connection... the pump primes whatever... but the ecu wont neither open the injectors (or switch on the pump as that needs the engine to be faster than the starter) unless it sees signal from the coil..

And as those wires run under the plenum inlet where your AFM 'blew out' I'd be rather suspicious wink

As mentioned before get a test lamp on any of the injector plugs & see if they are firing.

Okay update, first of all, compression. Did a check and all were above 140 without any oil added as I didnt have any to put it....I put a bulb into the injector plugs and ALL of them were firing.

I checked my spark - as I have the wrong plugs, i have b7rcs the resistor version, with resistor plug caps and resistor leads, it has a very weak spark coming out of them, the coil produces an immense flash of light so thats okay.

any theories?

I'd still go for wrong ignition timing.

Was the cam replaced? Wrong cam timing possibly?

Id go for ignition timing too.
Have you turned the engine over with spark plug number one removed and checked that on the compression stroke the rotor arm is pointing to the correct position on the distributor cap ie. the lead that goes to the number one spark plug/piston.
You should be roughly trying to get the piston at top dead centre.
Use a socket on the crank nut to turn the engine over slowly not the stater motor and use your thumb to seal the spark plug hole and generally you can feel the piston either sucking or blowing (compressing).
Hope this advice doesnt insult your intelligence but the basics need checking first.
Its easier with all the spark plugs removed also.
This is a quick method of checking the distributor isnt 180 degrees out. They can also be 45 deg out from memory.

So when it is on its compression stroke, turning the crank will then inturn turn the rotor arm to no. 1? - Or should i just turn it untill it is at number 1 and see where the piston is with a screwdriver?

The screwdriver thing will not tell you if its on the compresion stroke. Just thats its at top dead centre. 4 stroke engine Suck squeeze bang blow.

Okay dokay, and If i find that on the compression stroke it is not facing to point no. 1 - what do i do then? turn the distibutor until it is?

Assuming it is in the wrong postion.
Undo the distributor clamp, take distributor out slowly, it will disengage from the cam shaft drive gear that is located on the end of the distributor.
Then turn the rotor arm so that it points to the correct ht lead. This should be the one that goes to no1 piston.

When putting distributor back in you will notice it mesh with the cam shaft gear again.

Sometimes the rotor arm position moves when its fully home and no longer points to the correct ht lead so you may have to remove again and turn a little bit more or a bit less. Its a bit trial and error but when clamped back down it should be in the correct position.
This assumes it has the pre serp original 430 engine. Basically your alternator drive belt is a narrow width one. If in doubt I can send you a photo of my 430 engine.

One other point there is a slot on the end of the distributor that drives the oil pump, this must drop onto the flat drive pin of the pump, if the distributor does not push down fully home then this may need turning, it is a pain to turn but can be moved using a long flat bladed screwdriver. Above all do not force anything. If in doubt send me an email and I will forward my phone number.
