Are you try scanned the PCM to know if some fault codes are stored there? Are you check injectors? We recommend to de-pressurize your fuel system. Disconnect the power to your fuel pump, by either disconnecting it's power supply, or pulling the fuel pump fuse or relay. Once the fuel pump has no power, crank the engine for a few seconds. The engine might start, but should die a few seconds later. If it continues to idle, then you didn't disconnect your fuel pump.

Once the fuel system is de-pressurized, we can begin to remove various parts from the engine bay to help clear up room. On a typical system, there is a fuel feed, and fuel return. For these types of systems, you would need to disconnect both of the lines, and then disconnect the fuel pressure regulator. The fuel injectors are held in with clips that hold the harness to the injector. Remove these clips, and pop off the wiring harnesses. The fuel rail is held in with a few bolts. Remove these bolts, and then the fuel rail should be loose. Pull the fuel rail out of the intake manifold or cylinder head, and you can now easily remove the fuel injectors.

Couldn't start his but had 40 psi fuel pressure, but even though it turned over. Are you check crankshaft, this is located crank sensor under the a/c compressor, to the left of the balancer. The camshaft sensor is in the timing cover usually behing the PS (Power Steering) fluid tank. FInally, try jumping or bypassing the fuel pump relay to test if have pressure, if this work, then go to the next device, fuel filter, then next at fuel pressure regulator and this way so on.

Keep us updated.

The MAP sensor is under the hood on the firewall , it has a single vacuum hose going to it , and a two wire plug.
simply unplug the wires to test it (if the van runs better w/o it pluged in , replace the sensor).

Jerky accelerating, late response to gas being pressed


Well for one, make sure you speed up slowly, dont HIT the accelerator. It may also be problems with your fuel filter. After you are stoped fuel stops running through the fuel pump/filter and then when you start going its starts to run through again and it cant keep up so it gets bubbles in it and doesnt move throught the filter easily hence the jerky accelerating. Good Luck
