Long crank starting issue

[thstone]

Check the MAF again. Unplug it and let the ECU use the base maps to see if it runs any better. At first it might run like crap, but it should settle down. If it settles down and runs better, then replace the MAF. If it still runs poorly, then I'd check the fuel pump for for proper pressure and flow. Low fuel pressure or volume will make the ECU go crazy trying to get the engine to run properly.
