Replying to: stupidcar1 (Sep 06, 2008 9:36 am) Ive have my 01 Blazer ls for about 6 years now. the only major problem ive had happened about 2 years ago. Had to replace the fuel pump(that was fun dyin on the highway in traffic!) and I had to replace the cat converter(made the car run like total crap and actually died on me going up a mountain) which i think might be one of the problems being discussed on here by some. I am also having the "I dont want to start for you today" fight with my truck as of late, I dont have a keyless entry system on my truck so i dont know wtf is wrong with it now. I've put a new fuel filter new plugs, i'm fanatical about oil/filter changes, i've even put a new hot wire to the starter(old one wore out-damn those dirt country roads!) So I hope my fight with my truck might offer some insight into some of the problems you guys are having. Replies to this message: stupidcar1 (Mar 28, 2009 7:15 pm)

Replying to: joem41577 (Mar 28, 2009 6:18 pm) I had another blazer before this one and it was doing the cough cough thing when it would get up to normal tempature. I called my grandpa, a chevy man from the begining of chevy, and he told me to change the ignition module. He said there is a jell stuff between it and the distrubutor and if that brakes down then it wont work right. I went to get one, Im a woman, and was told OH NO it cant be that its this...... Over and over and nothing they were selling me fixed the problem. Finally after about $500 I bought the $40 part. My husband put it on and BAM the problem was gone. Should have listen to grandpa from the start!!!!! GOOD LUCK!!

I have a 2004 Chevroletr Blazer. Battery light was on check battery found it was bad. Replaced battery but light stayed on. Moved vehicle and light went off. In this time the gas guage won't work the ABS and air bag lights were on. Left vehicle set for two hours and will not start. Any answers?
#16 of 19 @001 2wd blazer 4.3 Still no start. by billw67 Nov 01, 2009 (9:42 am)
All right to sum this issue I'm having up....I turn the key and it cranks.I do have spark.However the fuel pump doesn't engage.Not even to prime.Have replaced the keyed tumbler in column as well as ignition switch.Have removed all the after market crap that previous owner installed.So now is bone stock.Have checked relay and fuse.Both are fine how ever relay does not click.Have bench tested the fuel pump.It does work on the bench fine.Have considered adding a backup harness to the fuel pump.(relayed of course.)To engage the pump manually.How ever before I do this, (have done same before in a 90 camaro)I'd like to try changing the oil pressure switch and or sending unit.Have been to auto parts store and seen the switch.How ever CAN NOT locate the blessed thing on the engine any where.Could someone please give me a location and or explanation? Thanx.....Bill

98 blazer won't even crank. The key on you can hear the pump working, also the starter contact relay under hood is engaging, all lights and dash lights come on, chimes work, battery fully charged, The security system has been suposedly removed by some so called mechanic shop. tried to giggle the shifter in the park position and also the neutral position. open for any and all suggestions.....

Replying to: rnrmountains (Nov 08, 2009 11:42 am) Starter. I had one do this to me years ago. The bendix will engage, but if the brushes are badly worn, the starter motor will not turn. Most auto parts stores will test it if you bring it in. Replies to this message: rnrmountains (Nov 10, 2009 7:52 am)

Replying to: jlflemmons (Nov 09, 2009 7:01 pm) Thanks, Your exactly right. I performed the repairs on sun eve. The selonoid was bad. after doing voltage tests I removed the starter and tapped on the side....It worked.. I should have trusted my first instinct about this whole thing.... Thanks again
