    Default Hummer Problem

    Hi has anyone had a problem on the H3 when starting it it dies after a few seconds and when restarting it's as if the battery is dead. I put a new battery in and the problem is still there. If I disconnect the battery and reconnect it the hummer starts up and runs fine with the engine light on. After a couple of stop starts the engine light goes out. This starting problem happens about once a week and is getting more frequent. Any advice will be appreciated Thanks

    Hi Hummer3. Do you have access to a OBD2 scanner to find out what the error code is perhaps?

    Picked up a number of errors pointing towards the PCM (unprogrammed PCM was one of them). It might as well be that we have to get together with Sennin and do an upload.

    Klink soos 'n slegte aard (earth) konneksie. Elke keer as die battery ontkoppel en gekoppel word is die earth konneksie vir daardie oomblik weer ok. Die start wat klink asof die battery pap is kan dalk dui op 'n starter fout ook.

    Ek het eenkeer op my terrano 'n battery verkeerdelik vervang net om later agter te kom die starter was besig om op the pak....

    Kan nie skade doen om net die earth konneksie te check nie...
