RE: 4WD issues

Good chance it is the transfer case encoder motor. When they start to fail you get intermittent problems shifting into/out of 4wd. Sometimes you candisconnect the battery and when you reconnect it...

RE: intake gaskets...

One thing to consider... if your 4.3 is older the lower intake bolts are SAE 3/8 x 16, not metric. They look almost the same so make sure to check what you have. You should chase the threads in the...

RE: Blazer Wont Start

I'd agree that is is very likely to be the pump if the relay is working. Could also be the wiring going to the pump, though very unlikely. Could also be the electrical connector on the tank (a little...

RE: Blazer Wont Start

You mean price for a fuel pump, not filter, right? I didn't check today but IIRC the pumps alone are ~$100 and the entire assembly ~$250. Check Rock Auto, or the usual places Advance Auto or Autozone...

RE: Wont Start!!!!!!

Check the fuel pressure. It's very likely that the fuel pump is going or gone. When one of these motors acts this way that is the first thing to check. Checking spark is a close second but low fuel...

RE: 96 blazer hot start problem

To narrow things down you really need to check for spark and put a fuel pressure gage on it when you are having the problem.

RE: Blazer Won't Start

Sometimes instead of failing outright the fuel pumps start getting weak, meaning they put out slightly lower psi than they should. If so, sometime the motorwill start, sometime not. Also, cycling the...

RE: Blazer Won't Start

Almost surely fuel pump or fuel pressure regulator. Check fuel pressure at the rail.... needs to be ~60. Wouldn't hurt to check for spark to be sure.....

RE: how to and tools to R&R knock sensor 4.3L code W

Got that sucker! I tried the channel locks... not enough grip. The vise grips did the trick. No finesse, just brute strength. Sometimes that's the only way. :-)

RE: removing a/c compressor on a 4.3l 89 blazer

That may be worth a try. But it looks like the darned things are installed with red thread locker so it'll take aome real torque. Not sure if any crimp will be up to that. Bt I'll give it a try...
