Asked by Dec 18, 2015 at 01:59 PM about the 2003 Chevrolet Silverado 1500 Ext Cab Short Bed 4WD

Question type: Maintenance & Repair

Last weekend I took my truck ,2003 Chevy
Silverado 4x4 out mudding, it was running great
had a blast, went to the car wash and washed it
and on the way home it started cutting out real
bad, I put has treatment in it thinking it may have
gotten water in the fuel and my gas millage was
like 7mpg. I changed the fuel filter and it was
horrible, it seemed to be running a little better, then
last night we were out riding and going maybe 15
mph and it jUst quit moving, the transmIssion fluid
levels are perfect and there was no oil or anytHing
anywhere, I tried all the gears and even tried four
wheel drive and it still won't go, the rpm well go up
when you rev the enGine but it won't go anywhere,
this is my only veHicle and I'm a single mom so
any advice would be greatly appreciated

I am guessing you got water into the spark plug boots. I would remove the wires one at a time and dry them out. Apply a little dielectric grease to the boots at both ends of the spark plug wire to seal out moisture.


If the wires are in bad shape, replace them.


Thank you, I did crawl under it and have my son switch gears and I can hear it clicking and can see it changing gears and the reverse lights come on when I'm reverse, it starts and idles now it just won't move
