#177 of 497 2000 Chevy Blazer won't start after driven a few miles
Jun 30, 2008 (8:08 am)
I have a 2000 Chevy Blazer 4.3 engine. Recently changed fuel pump & filter, cap, rotor, plugs, plug wires and coil. Starts fine when engine is cold and drives well. I drive 13 miles to work, when I stop engine, it won't start back up unless I wait about 10 to 15 minutes. Notice an increase in fuel consumption after pump was changed. No SES light and no codes show up on reader. Repair shop is not helpful anymore. The wife is aggravated and so am I. Please Help!!!

We had a similar irritating problem with our old Blazer. Would start fine cold, but not when warm, unless you walked away and left it for 15 minutes or so. It would also start right up with jumper cables. After trying any number of things, we finally replaced the battery. It seems obvious now, but at the time we had been assured the battery was fine. It wasn't and the old Blazer starts fine all the time now.

I have a blazer 98 that have problem starting. The instrument panel is not working properly. From time to time the temp and gas gauge will go out and the security, gas and batt. light will go on, sometime will fix itself an the car will start.
The electromechanic mention that is the Instrument panel Cluster the one causing the problem and I can not get a replacement for it. please assit.
#181 of 497 1994 Bravada won't start
Jul 18, 2008 (2:07 pm)
I have a 1994 Bravada 4.3 CPI Engine - Vin W, 135,000 miles on it. I own the car about 4 and a half years and is used mainly as a 2nd car and in winters. (4 wheel drive vehicle) About 3 months ago I was driving from Pa to NY, about 120 miles each way. It is mainly highway driving. I was near my destination on the highway, when it stalled out on me. I pulled over and it started right up. Then after I got off the highway, it started to stall out by every light and stop sign, and again it started right up each time.
On my way back home about 6 hours later, again it was doing the same thing. Once I got to the highway it ran fine for a about 105 miles. Once I got to my exit on the highway and got off, the car stalled out again. This time it would not start up. So I had it towed back to my house. The next day it started right up. I shut it off and I went to buy new spark plugs, distributor cap, rotor, ignition coil, PCV valve, and fuel filter. I had the fuel pump changed in May of 2005 (about 15,000 miles ago) The fuel pressure is 58 with IOEO. It still does not start. I do not have any engine light on.
I went to a salvage yard where you pull your own parts. I got a used Map sensor, IAC sensor, TPS sensor, EGR valve, CPI unit and a computer. It was from a vehicle that was in an accident. I changed parts one at a time. It still won't start. I checked the oil, I do smell gas in it. I know that means that there is a leak somewhere. I'm not sure what that means nor how to look for that?
I also read in your posts that it could be the Crankshaft Position Sensor. I have the Haynes repair manual and it does not mention anything about it. Can any one please tell me where it is and be specific about it and is it hard to change? Can someone also tell me if you could start the car with the Air intake plenum off the car, or does it have to be on and under pressure?
Thanks for all your help.
PS. You guys are great! I learn so much from these forums. I feel like I could one day become a mechanic from these forums.

Look from under the front bumper at the underside of the crankshaft, about the 7 o'clock position and you will see it. Has a plug going to it with three wires.
If you have a hard failure of the CPS, there should be a code set in the computer.

Thanks for your quick reply, will check it tomorrow. It does not set a code on the computer.

I know how it can be...sitting in traffic and have the car refuse to run. I replaced the fuel pump one time and had the same issue reappear after about 30 days...The pump simply did not go on when the key is turned(normally you can hear it charge the fuel line and stop moments after turning the ignition key to the ON position. Well the fuel pump package does recomend replacing the harness and it is normally supplied with the pump...I did this and on the next hot day with the AC running, the car stalled. I could hear the pump charge the system, but the car acted as if it had no spark. It turned over just fine...just would not start. Then after about 15 minutes, it fired up no problem. IT IS THE FILTER. From 2000-2003 GM had an issue with the fuel filters causing the pump to register a charged line and subsequently shut off before the injector actually had enough pressure to send a supply into the engine cylinder. So it acted electrical when the problem is a clogged in line fuel filter. A $16.00 fix and it runs just fine now. GOOD LUCK tchill93.

Oddly enough...it may be the inline fuel filter...the pump is charging the system to what it thinks is full...then shutting of. If the filter is clogged, the pump does not know the injectors don't have enough pressure..because the pressure is between the in line filter and the tank...

It's just the inline fuel filter...$16.00 at any auto parts store...the part is located just under the drivers seat on the frame rail.
