MS PNPPRO mx5 90-93 vvt swapped

No Your fuel pressure should be 300 Kpa or so.

What might be causing this issue then ? FPR is hooked up the right way according to the megathread. And the feed line and return line are correct aswell.

Ok now I'm confused.
Just changed the spark plugs cranked over and when checking if they are wet or not they aren't. In testmode I can fire them all but when cranking there appears to be no fuel. What is causing this issue ?

Flow test you fuel pump. It sounds to me like it's working electrically but not building pressure

Megasquirt doesnt read fuel pressure unless you have an aftermatket pressure sensor the pressure is fine. I got a bit closer to the solution => There was no crank and cam sensor signal when doing the diagnosis thing. So I'm rewiring the tps and both sensors to the additional pins on the megasquirt. I will see if that solves the issues

I'm well aware of the fact that MS doesn't read fuel pressure unless you have a sensor set up for it. But YOU posted fuel pressure readings so I assumed you had one. The aux upgrade wiring is really for using a newer harness and engine ( 96-00 depending on the swap, 01-05 uses a totally different ECU connector). Get a composite log of the engine cranking and we can see what's up.

I have a '03 vvt engine in it wich does require wiring changes. And I ment connector 3 on the ecu.

Yeah I understand, Connector 3 is for 97-00 harness swaps.
