Is the earth wire bolted on the head from the pcm?

Fuel pressure has been checked and is within specs and does not leak down.

I am think all the wiring is right but will double check again. Is the pcm earth the one bolted to the back of the head near the coil?

define "within specs" ? what psi was it? and where did the spec come from?

there are two earths. one at the back of the head and one on the front near the alternator.

when you swapped the dizzy did you put it back in with number 1 at TDC firing stroke .if not the plugs will just get wetter and wetter from incorrect timing.

Earth wires are all good and fuel pressure is between 230 - 315kpa as per specs in VS manual. Timing is correct and engine will start and run with manual fuel restriction ie shutting down pump or clamping fuel hose so have ruled out any mechanical problems or stupid stuff like leads on wrong etc.

is it using the standard injectors ?

Post by **delcowizzid** » Wed Apr 09, 2014 1:03 pm

injector stuck open or wiring for injectors shorted to earth or fuel reg vacuam hose pissing out fuel or ecu driver caput

Injectors are standard and hold pressure with pump off so have ruled out stuck injectors. Tested + at both terminals on injectors with ignition on and injectors pulse (tested with noid light). Vac line from fuel reg is clear. Not sure what you are referring to with ecu driver, is that the ignition module? If so that has been swapped over and tested good. My brain hurts.

Sounds like the MAP sensor.
Check the line from the front of the manifold (it's connected to the intake under the throttle body area) through to the map sensor.
If the map sensor cannot see manifold pressure the ecu will assume that the engine is at a high load condition which will add additional fuel.
This line will get brittle due to heat and will snap.
Also make sure that the map sensor is located above the intake manifold. If it is set lower, the line can fill up with fuel.
Have you checked for trouble codes?
