08 lsv hard to start!

[Rakkasan]

I'm guessing this is the Crank Position Sensor? Found it located on the front/port side of the block behind what I'm guessing is the Harmonic Balancer.

Also would a bad sensor cause a crank and hard to start scenario but still allow the engine to run fine and smooth once started?

Yes that's it. Yes it could not always the case but a possibility.

I'm sure this isn't it but make sure nothing is touching the kill switch at all. I found out the hard way that those kill switches are incredibly sensitive. I had a hat bump it every now and then and the engine would stall. I just jumped the wires to it together and took the kill switch out of play. Good luck . Let us know what you find.

Ok just left the dealer... Hooked up to the computer I was getting map sensor fault but the technician said he has seen a bunch of ignition switches go bad in these. So we looked at voltage on his computer and sure enough it had 12volts until you started to turn the engine over and it fell to 0. Sure enough we plugged a new switch in and it starts right up. The switch was like $30 or so.

That is great. I love it when it is a cheap fix, although you ended up doing a lot of other things.

I know me too! And thank you and everybody else on this great forum for your help! I'm thinking about removing my kill switch too for that reason.. What if anything did you put in its place?

I left the switch in place and just disconnected the wires from the switch behind it and connect them together.
