Help getting car started
Discussion
Cars been off the road a few years, 99 chimaera 450. Its running a emerald ecu, get power to ecu and can connect pc, throttle,water,air temps all read ok changed plugs (old were wet and rather black) running the two ford coil packs tried a plug on each pack and can see a spark (no massive but was in direct sun outside). Engine turns over fine its just not even trying to start.
a - Assume I would not get a spark if the crank sensor was not working (may have abit of oil from where pas U leaked)
b- Fuel pump has been replaced original was std chimaera but I think it gummed up with old fuel, now have the pump fitted to cerberas I belive the old was a 3 bar pump new one is 5bar capable. Have an FSE reg set at 3bar so assumed the biger pump would be ok as excess would be taken care of by FSE reg.
c - If fuel pump gummed up could I have a problem with the fse reg or injectors (these are pretty new 4 hole red bosch ones fitted before lay up)
Can't test fuel pressure atm as don't have a gauge need to get hold of one.
Fuel rubber lines, fuel filter are new, and tank has fresh fuel.
Any ideas to anything else to try

You should be able to scope the crank sensor, see down the page initial starting.

Impossible to say how your emerald has been wired but if the ECU is still running through the original immobiliser I'd start there 
On the 14CUX original setup the ECU circuit and the starter solenoid are both interrupted by the immobiliser, which is a known failure point because the Meta immobiliser has two relays, one is high amp and one is low amp. The low amp Meta relay was intended to support the low amp ECU circuit, while the higher amp relay was intended for the starter solenoid circuit.
Of course what TVR did was wire the lower amp ECU through the higher amp Meta switching relay leaving the low amp one for the higher amp starter solenoid. As one might expect, what tends to happen is eventually that overloaded low amp Meta relay eventually burns out, this may or may not appear during hot weather as we are having now. As we all know resistance in any wire/cable/circuit will increase with heat, this is also why the issue tends to raise it's ugly head on hot re-starts.... Hence the term 'Hot Start Issue'!
I would check to see if your Emerald installer used the same ECU live feed as originally used with the Lucas system.... which is highly likely, if this is how its wired your Emerald will be controlled by the Meta immboliser in the same back to front way TVR wired the 14CUX ECU.... which means no difference in terms of the pish poor reliability TVR hard wired into every Chimaera & Griffith during the 1990's
TBH on the TVR Chima & Griffs the problems mostly effect the starter solenoid circuit for obvious reasons, but you need to accept a Meta security system is early 1990's Italian electronics
, so while Meta installers will try to persuade you Meta are the best thing since sliced bread you only need to have experienced a 90's Alfa/Ferrari/Maserati to know the truth.
1. Is your starter motor cranking the engine?
2. Is your Emerald getting +12v?
Remember the ECU (whatever make) controls the fuel pump, so no power to the ECU = no fuel pump buzz

If the rings have stuck in the pistons then compression would be down. Crank sensor will provide the spark reference but as said above, without a nice square wave signal it could be erratic.
If you hear the fuel pump run and prime when you switch the ignition on then I would be trying a tow. This will ensure the engine is turning fast in case of any compression loss.

Engine is turning over. And fuel pump is priming.
Changed the plugs and they were abit black and very wet with fuel
Ecu works as pc can see diag screen
The fuel reg is a fse/malpasi 1:1 the fuel pump wasn't working think the vains got gummed up with old fuel so fitted a cerb pump which is a bout 20% more flow but rated 5bar instead of old std at 3bar woukd this mess up the fuel reg?
