03 CTS starting/stalling problem
About 2 weeks ago I pulled into a convenience store, went in for 5 minutes, came out and my 03' CTS wouldn't start. It cranked, just wouldn't turn all the way over. I called a tow truck and by the time they got there 45 min later, the car started.
2 weeks go by with no problem.
I get gas, pull out of the station and stop at a stop light. Stalls. Will not start, just cranks and wont turn over. I have to push it out of the intersection. 2 hours later I return and the car starts. I drive it home to pick something up before dropping it off at the shop and it stalls in the driveway while I run inside. Won't start for an hour. I bring it to the shop, they get to it the next day. They CANT MAKE IT STALL! They can't duplicate my problems, it just keeps starting like a champ. They are going to look at it again Monday.
Any ideas? Mechanic thinks it may be fuel pump but wants to be sure. No codes or check engine light.

RE: 03 CTS starting/stalling problem
Thank you for the reply. I had read a lot of problems with the crank sensor also, but it seemed like most people were able to start the car back up when it stalled when it was the crank sensor. I did read of a few people that weren't able to though. So is the crank sensor the same thing as a crankshaft sensor?

2003 Cadillac Cts crank sensor
My cts is having problems starting. Runs fine then all of a sudden won't start. I wait 10-15 minutes it cranks up. Have had the crank sensor replaced two weeks ago everything was fine. Today I go out and it does it again. I wait 10 minutes it starts up. I took it back to my mechanic, no codes are showing up. Help. I want to go out of town but am afraid of getting stuck at a random gas station or worse.

intermittent are hard on a ten year old car. fuel pump(s)and related circuits & ignition module wont always set codes. Normally fuel pump has a hum that could be heard, you just have to note about everything related so your mechanic might duplicate no start

starting problems when hot
Hi
I need some help with this problem I am having with my 2003 cts. The problem started several months ago. The car will start fine when cold when the car reach operating temperature or on hot days it starts intermittently. The engine turn over slightly but not fast enough to start, I general raise the hood and let the car cool down for ten-fifteen minute it will start fine. I decide to replace the starter which is not easy to replace, you have to remove cat converter. When i installed the new starter the car will not start new starter sound like it's dragging I took the starter back to the store and they bench test starter the starter pass the bench test. They gave me my money back, I brought another starter form another store install the starter same results as the other new starter I bench test the second started it work fine. I installed the original/old starter car started fine. Check codes, check voltage from hot battery cable showing proper voltage double check new starters installation. Can someone tell me why the new starters want work? I needs some help with this problem can someone give me some tips. I thinking crank sensor or +/-battery cable problems, is crank sensor hard to replace?
