#3108 of 3449 Fuel pump fixed... by 00jimmy Jan 07, 2008 (12:05 pm)
After replacing several fuel pumps in less than a year, we looked at other problems which could cause the pump to stop working. It turned out in our case that one of the connections on the plug was corroded. It seems the bad connection to ground was our problem. Just cleaned it up and added a bit of dielectric grease. Hopefully it will run for a while now...
#3109 of 3449 ignition problems by morenolm Jan 08, 2008 (9:14 am)
I have a 98 Jiimy 4.3. About a month ago it started having problems starting. No engine comes on. Had the ignition module, the regulator, coil, distributor cap switched. The battery, alternator, starter, and the fuses are all good. There is a alarm attached can this hae anything to do with it. Replies to this message: 0128 (Jan 14, 2008 5:08 am)

Replying to: morenolm (Jan 08, 2008 9:14 am) If your alarm has a "kill switch" function, it can certainly disable your ignition. If it is an aftermarket alarm, check with your installer / shop / or look up the manufacturer online for trouble shooting.
#3111 of 3449 Fuse trouble by c5nut Jan 16, 2008 (3:55 pm)
I have a 2000 Blazer and for the pastweek I've gone thru 5 10 amp fuses for the courtesy lights. I've read some posts about this but still unsure where to start. I've read a few posts that suggest checking grounds for the connected components (lamps) but, where are they? Are they near the bulb fixtures themselves? Thanks

Replying to: clancy1 (Feb 04, 2006 4:04 pm) Found it easy to replace that plug if you unbolt the steering box and pry it up out of the way. Only 3 bolts on side of frame to unbolt the gearbox. These things are the biggest piece of crap ever built.Designed to fail.No wonder GM is in trouble. Between the multitudes of problems with these blazers,they can't make a decent tranny and use the crappy orange dexcool antifreeze which destroys the whole cooling system and eventually the engine.

#3113 of 3449 T-stat '02 Cevy Blazer by redgms Jan 20, 2008 (9:28 am)
I was hoping someone could help me by letting me know where the t-stat is in my 2002 chevy blazer. I have been all through the engine and the manual and can't find squat. Any help would be appreciated.   Thanks... Replies to this message: c5nut (Jan 20, 2008 6:26 pm) jlflemmons (Jan 21, 2008 6:38 am)

Replying to: redgms (Jan 20, 2008 9:28 am) I have a 2000 4.3 and my thermostat is in the cap of the radiator (top of radiator, passenger side).

Replying to: redgms (Jan 20, 2008 9:28 am) Follow the upper radiator hose back to the top of the engine. The hose attaches to the thermostat housing. Chevy thermostat housings are usually held on with two bolts. Be careful when reinstalling and check that the thermostat is fully seated, the gasket aligned, and the housing is sitting flush before tightening the housing. Many a housing has been replaced because it was tightened down on the lip of the thermostat and cracked.
