Question about 2001 Chevrolet Silverado 1500

Starting problem when warm

A friend of mine has a 2001 Chevy 1500, 4.8L v-8. The problem he has is a no start problem when warm. (It will crank but will not start) It will do this once and then will start normally. I have tried to check for any codes with a handheld obd2 code reader, but the reader does not work on this vehicle. I tested it on my van to be sure it does work. So I do not know if any codes are set in the computer, but the check engine lite is not on. Any ideas on what to check first and, save some troubleshooting time?

Thanks,
Mike

Engine cranks for 8-10 seconds before it starts when engine is warm


you must RUN the SCANNER/computer for better diagnostic and fix it. YOu can have some faulty like: PCM+BCM+ignition coil, sensor, etc. see the diagram attached.

1999 chevy express 1500 van hard to start when cold. will start up fine with a shot of starting fluid. no engine codes. starts fine when warm


I had same issue. I thought it was a fuel delivery problem but I then noticed that while I had it on a battery charger it started up immediately. I noticed that the speed of the starter/flywheel was significantly quicker leading to the conclusion that the battery just needs to have more cranking amps. When I told this to a mechanic friend of mine he told me that it had something to do with the computer and that I just needed a better battery, more cranking amps. I just bought a battery today might even get a bigger one

2001 chevy silverado won't start when warm


Possible weak spark from ignition coil or low fuel pressure due to weak pump. Try spraying carb clean into intake throttle body when problem is present. If vehicle will start and run with a little spray then fuel pump is failing.
