that's possible too. the contribution code is what leans me towards my original thought. usually a hpop leak will result in a low ICP cranking code, P2291
usually a misfire develops in one bad injector and as it progresses the rest on that bank are starved of fuel
you can try one thing. let it heat up to the point where it dies, pull your fuel pump fuse, pull off the secondary fuel filter cap and filter. have someone crank the engine while you watch the fuel bowl for compression bubbles emerging from the lines
okay the book says pull the FICM relay. that's probably a better idea
