Hummer h3 cold start problem
the new maf and see. The parts should arrive in few days
I need to get that electrical cleaner I used the same cleaner for the maf and I also have the other one for throttle body mad and throttle body is clean but that electrical cleaner will come handy to clean that fuse box
UPDATE
so I got the fuses, the new MAF sensor and I also got a new crankshaft sensor just for the hell of it, installed the new crankshaft , disconnected the battery and sprayed electrical cleaner on the fuse box installed new fuses after it dried off I even cleaned battery terminals and installed another battery terminals because the ones I had before were aftermarket but really old. Started the car no problem. This morning it was 55 degrees. Crank it stars right away! That’s great. We will monitor it for few days specially on cold days to make sure it still starts fine. I hope that resolved the issues. I will Keep you guys updated . Wife says the car drives better too after replacing the maf sensor so we shall see . I appreciate everyone’s help I’ll update in few days

The car seem to start right away and it sound like the problem got resolved. Thank you guys so much for helping me fix this problem that other 3 local mechanics couldn’t figure out! Anyone in the future have the same problem make sure to check the relays, crankshaft sensor and lastly the maf sensor
