Codes:

I've read the codes on all the modules with he durametrics. The alarm module has a fault 21 (immobiliser w-lead) stored, but no active faults. I have no idea if that immobiliser code is recent or ancient. v6 (beta) of the durametrics reported no active faults, and I told it to reset all faults just in case. I also grounded the positive and negative battery cables to discharge capacitors in the memory. The remote works.

Fuel Filter:

I can't get to the fuel filter. While Pedro's description isn't bad, it is not a safe job to be doing without a lift. I would like to check the fuel line at the engine to see if I'm getting flow through the filter. Does anyone know the quickest way to get to the fuel rails to check fuel pressure downstream of the filter? It can't hurt too much to check that.

However if it was the fuel filter I would think the fuel pump would be on continuously attempting to get fuel to the engine. The fuel pump relay works, but it is not turning the fuel pump on.

Air:

I disconnected the MAF as someone suggested but I didn't get any change in the conditions. Not ot over simplify things, but there really isn't much more to a modern cars air system than the MAF and throttle. If the throttle were bad it should still idle, even if it's rough. When the car first died and I could still get it to start and idle roughly it would respond to the throttle a bit. It's possible that a nearly complete blockage of the intake would cause the problems, assuming that it would result in the DME shutting off the fuel pump.

Spark:

I don't know the condition of the ignition. I'd hope that I'd get a CEL or fault in the DME if there was an issue with the spark to all the cylinders. If it was just 1 or 2 it would still run just poorly and throw error codes.
