2001 SLS won't crank
I have a 2001 Seville SLS that won't start. The problem started out as once maybe every three or so months, when you would turn the key the starter motor would turn, but ridiculously slow. But if I let it sit for awhile, and held the in start position the starter would actually speed up and start the car. Every time after this happened the computer would throw a code p0340: Camshaft position sensor circuit. Well a week ago it started doing the same problem again, but instead of letting it sit for a few minutes and it works, it's sat for a week and all I get is a single "click" and I have the p0340 code again. I've checked the battery, replaced the CPS, and still no luck; still have the same code showing up after I installed the new sensor and cleared the codes. Any ideas on where I need to go, or check out next?

I've checked the connections on the battery so my guess then would be on the starter. Is there any "shortcuts"to check the wiring on the starter without removing the intake manifold? Also, would a loose connection keep throwing the p340 code?

Re: 2001 SLS won't crank
P 0340 is a CMP code - no relation to weak starter. CaMshaft Position sensor. Loose/corroded connector possible.
The intake manifold must come off to check the starter, and you would not be the first to find a loose positive cable, bad solenoid (IGN start) wire, or corroded starter-to-block flange (bad ground).

Thanks for the advice! I'll start working on pulling the manifold off today. Another question I have is p0340 code has only come up when the vehicle hadn't stated. Could it be tripped up by a lack of voltage to it from a loose connection?

Anything is possible, but my guess would be P0340 means the sensor has failed.
