Hello all,
Past few days my truck has been dying at stoplights and wont start unless I let it sit a few minutes (which is a big problem as sitting through a stop light in Minneapolis isn't thought of too fondly). This morning I was headed out and couldn't get it to restart so I pushed it home as I was only a block or so away. Got home today and sure enough it fires right up, pulled it into the garage with it IN gear and stopped it dies after a few minutes. However it seams as though if I turn the key all the way off and wait till I can here the fuel pump finish priming it will start. Once its warm it seems to run fine.
Here is where I am at -
OBDII codes for misfire on cylinder 2 and flexfuel sensor (both of which I've had for a long time)
Tested the TPS sensor
Tested the IAC sensor (read it should output 10.5v I was getting 12.5v, but it ohmed out correctly so I don't know if the variance is acceptable)
Cleaned MAF
Switched the fuel pump relay with another and no improvement.
Thanks!
