my current car pulls a p1000 and it starts fine

p1000= "injector circuit/open cylinder 9"

idk if that help much buts the little i can help with other than checking simple things like voltage and fuses, check all wires and try the shake tests, but im guessing u did that all allready

 

alright i had the ford dealership closest to me take a look at it and this is what they said
the code can mean a few different things but in your case it has to do with a sensor on your first cyllinder which went bad, dumping a bunch of fuel into it and flooding the cylinder, then eventually gas leaked into oil, so the remedy was replacing the sensor and changing the oil...idk what the name of the sensor was but thats what happened, he said if your ever running that code you should probably have your car looked over because if it is one of the sensors that went bad on my car it will slowly fail, so if you are pulling one at any point in time your car will refuse to start, and its not so good to have fuel in your oil, so if your pulling a p1000 and your car isnt starting or is running really shaky (letting off throttle and encountering some shakiness) get it checked out
