Replying to: buzzh (Nov 18, 2008 6:17 pm) First, be sure the #1 cylinder is on the compression stroke at TDC. If so, and the dist is pointing to #4, there has to be a break in the valve train. First thing to check is that the timimg marks still line up on the timing gears, cuz it sounds like the thiming chain has jumped teeth. If timing gears/chain are good, and distributor is good, then must be camshaft related, but I've never heard of this actually happening, it's usually the chain/gears.

#3312 of 3449 Blazer Starting Issue . . .AGAIN!!!?? by jpmccr Dec 01, 2008 (2:18 pm)
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!!!!!!!!!!!!!!!!!!!   Replies to this message: jpmccr (Dec 06, 2008 10:16 am) jpmccr (Dec 15, 2008 5:53 am)

Replying to: johnss10 (Nov 19, 2008 5:50 pm) Stup[id me, 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 Replies to this message: johnss10 (Dec 03, 2008 4:39 pm) bladams13 (Dec 04, 2008 7:13 am)
#3314 of 3449 96 chevy blazer 4wd problem by bladams13 Dec 03, 2008 (11:52 am)
i have a 96 chevy blazer that i recently had a new engine put in with 110k on the motor. it was sitting for about 5 months beofre the new engine was put in and driven again. when i got it back i put it into nuetral and put it into 4 hi and when i put it back into drive i went forward and every quarter turn of the front tires spinning it would make a loud clunking noise like something was grinding in the drivetrain. im not sure if its the front differential axles or something ive heard about the acuator?? any information and help is appreciated.

Replying to: buzzh (Dec 01, 2008 3:02 pm) Boy, I understand the frustration. All I can say is everytime I've had those symptoms (several), it's been the timing chain/gears.   I'm working on the same idea of the engine swap for my S10 pickup, not my Blazer. should be a lot of fun.

#3318 of 3449 HELP! by cobrabas Dec 06, 2008 (6:30 pm)
I just did the lower intake on my 99 blazer. put it all back together and fired it up. I fired up and i shut it down quickly. Went an ate dinner and returned to move it onto ramps to change oil before i test drove it and no it wont start. It cranks and sputters but wont kick on. Plugs are wet, i dropped the dristributer right back into place and my marks matched. dont know what to do or where to start.

Replying to: jpmccr (Dec 06, 2008 10:16 am) Last starting issue was also due to a really bad, messed distributor cap and rotor. Replaced and she runs fine.
