Truck stalled at red light and will not start.

is the check engine lite on need codes could be anything from fuel issues to electrical issues

2010 Silverado after rain or carwash truck dont start, lights on but no crank, i unplug the negative of the battery , wait a min, put it back on, starts fine, sometimes shifts weird, shuttoff than start again, runs fine. could be there a electric part like a modul or relais under the windshield or in the fender what cause this? not happening when its dry. need answers

I would check the vacuum lines thoroughly as one may have collasped or previous owner replaced with a substandard one,which may be partially collaspe then upon warming up will vacuum itself shut causing the motor to surge then fail to run or start if it happens to be a main line that is affected.

It might be the MAF sensor. I would try tapping on it while the vehicle is running to see if it will stall. Any check enigine light on?

Start with the simple and replace the fuel filter. The fuel filter should be replaced every 15,000 miles or once a year to ensure the fuel system is running 100%. Auto Zone will have the fuel filter and can give you the step by step instructions to getting the job done with common tools. If it's the fuel pump failure, you have not gotten the car restarted. Good luck and keep me posted, be glad to know you got your car running 100% again soon and please rate.

I just had a similar situation. The truck would run fine and then the Service Engine Soon light would start blinking and the truck would go into "limp" mode. It would eventually stall. Strangley though, if I turned the key over and then restarted it, it would start right up and run again. It ended up being the IPDM (Intelligent Power Distribution Module) that was bad. It cost me $520 to replace it.

okay try this....talk to your parts store and get a battery load tester, and find out if the battery is indeed dead. My guess is it sounds like the Altenator is dying. they are around 50-100 and can be install by a pro in minutes.

try replacing the throttle position sensor

That engine uses high pressure oil to open the injectors. Of course make sure your oil level is up then try turning it over while tapping on the IPC solenoid to see if you have a high pressure oil issue.
