Replying to: quantumtouchfl (Nov 18, 2008 6:49 pm) I've negelected Jimmy far to long. Pulled the radiator and the lower half was clogged. I'll pull the accessory brackets and pull plugs, it needs a tune up something bad. l just want it last till next summer when we'll buy something newer. Thanks for the advice and I'll post what I find, sometime this week. Buzz

Replying to: buzzh (Nov 18, 2008 7:30 pm) The transmission went down at the 162,000 mile mark... 3-4 gear clutch pack finally went. I purchased vehicle with 81,000 miles in 2004... flushed the transmission three times before it went down. I found a shop that had all kinds of test equipment... for testing the solenoids, valve body, etc... all the parts inside so that they knew everything was working before the put anything back in the tranny. They also insisted that the transmission be filled with Synthetic ATF... I had no problem with that... as I had never had the opportunity to use the Amsoil ATF. Trans runs about 50 degrees cooler. I currently have 182,000 miles... about two years ago I wanted to put a dist cap on with brass contacts. I order my wires, cap and rotors from Jacobs Electronics. The cap and rotor I orderd two years ago... turned out to have aluminum contacts when I opened it this last June. I did not change it right away... because I had just changed out the cap, rotor, and wires with AC Delco parts... I should have done so right away. Anyway... about six months ago I called around looking for a cap with brass contacts... AutoZone and Advanced Auto gave me a price of $65.00... too rich for me... so I just put it on the back burner. I checked again two weeks ago... Neither store carries them... so I ended up at NAPA... $41.00... I will be buying another dist cap next mount to keep on the shelf... my point is... the brass contacts made a big difference in idle and performance... still getting numbers on miles per gallon... but before I did the change... I was getting 20-21 MPG. Take care, TJ |

Does anyone have a diagram that shows the wiring harness to the shifter... plug has about six wires... locks the shifter when in park... grey is instrument lights... for the selector window... black is usually ground... I need to know what the other four are... one is pink... one is yellow... one is purple... if I remember correctly. Thank you, TJ |

Every time I'm towing a load ( tent trailer or utility trailer ) with moderate loads, going up hills causes the engine to misfire and lose power. Eventually, the check engine lights comes on to indicate P300 ( misfire undetermined ). What is the first course of action to take except an expensive tune up?

Replying to: pilot1122 (Nov 19, 2008 1:34 pm)  Misfire under load is almost always an ignition problem. You could buy spark plugs and try that. I don't recall if your year/model uses coil packs or actual distributor cap and wires, but if the latter you could replace those, too. |

Here's the poop: 2001 Blazer LT, 122,000 miles. Had the fuel pump replaced (11/25) and the fuel pump relay was checked (same time) and it works fine. Ok,I have driven it daily since the pump was replaced. Drove it to work and home on Tuesday. Took the wife's car to my Mom's Wednesday morning and got home Saturday. Got in it this morning (Monday) and low and behold it WILL NOT start. It sat for five days. It rained all day Sunday. I popped the hood and it looked like everything was covered with moisture to include the distributor cap. Turns over but won't catch. I hear the pump prime up but it will not catch. My wife tried it this afternon (sat for about 4 hours).I have absolutley no idea what is wrong or where to look. I am so over workng on this thing, I can't stand it!!!!  PLEASE HELP!!!!!!!!!!!!!!!!!!!

Replying to: johnss10 (Nov 19, 2008 5:50 pm) Being an old school 'wrench' I was accustomed to a normal distributor cap. I didn't realize that the actual contact for #4 was opposite from the #4 wire. I pulled the timing chain cover off and all was well. So I pulled the accessories off and cleaned everything. Bought all new tune up parts, plugs, wires, cap, rotor, Still no start and I hear that dreaded sucking sound coming out of the intake like a bad valve. Plus the backfire through the intake. So we're looking for another rig. I want another Blazer, but she wants a frickin' Pontiac Vibe......................  Thanks for the replies. But think it'll sit till next summer. Thinking about a 350 CI for it. Be a long term project a real sleeper. Buzz
