The intermitent factor is what leads me to believe its the relay/module, its hard for me to swallow the fact a MAF sensor could work fine and then be stuffed 10 minutes later simply cause you stopped the engine, and yet it works fine abit later on. The fact it wont work at all now with the MAF doesnt really indicate the MAF is no good, it could still be the relay/module has failed completely, in which case the intermitent factor will no longer be part of it. The fuel pressures you indicate there are fine, the drop off you see when getting off the throttle is the pressure regulator lowering the pressure, its controlled by vacuum, and when you get off the throttle, the amount of vacuum increases. The more vacuum in the manifold, the less resistance there is for the fuel to flow from the injectors, cause the vacuum will help to draw the fuel through, hence requires less pressure to flow a simular amount. |
