Hello. I have an '01 Chevy Blazer and recently it has started having trouble firing up. It will crank over and take probably 10-20 tries before it starts up. ONce started, it runs fine. Put in the guage, and just sitting, fuel pressure dropped from 48 to 10 within two hours, so.. We did a tune up, replaced the fuel filter before deciding on the fuel pump. We put a brand new fuel pump in yesterday and now it is still having the exact same problem. Battery is brand new, too. Any suggestions?

2000 Blazer Will Not Start

I have a 2000 Blazer that will not start. A couple of weeks ago on our way home, it just quit on us. It spit and sputtered once or twice and then just quit, like it was out of gas. We got it home, replaced the coil, had the module checked that is on the same bracket as the coil (it's fine), and checked the fuel pressure, which tested at 60psi with the key on, engine off. Can anyone tell me what I should check next? It turns over, but will not start. Any help would be greatly appreciated. Thanks in advance!

Cap and rotor first to rule it out and get a Delco - had a few problems with aftermarket ones lately. That module is the ignition module (older blazers its in the distributor). Then next piece would be the crank sensor under the front of the engine right behind the harmonic balancer that tells the PCM where to fire the plugs (timing) and also get a Delco or Standard motor part. All fuses were checked of course.

Any codes or SES light on? Fuel pressure should be min 60psi key on engine off - is it now? All fuses OK like ECM bat and ECM ign? Then cap and rotor if pressure OK cause maybe electrical. Then test the coil, and then the crank sensor.

Should be setting body code DTC B2960 and is for 98-01 blazers. Look up GM bulletin 01-08-56-001A and its 5 pages long so detailed - Passlock is getting incorrect sensor voltage to the BCM (body control module). Could be broken wire, connector, bad terminal, insulation rubbed thru, etc. Main wiring from column to all so it could be anywhere almost so suggest a GM dealer - they have done these and few others have. Sorry.

After checking the usual steps for ignition spark when cranking, if there is a spark then I would be suspicious of water in your gas tank. With the stupid problem of GMC fuel pumps burning out with low levels in the gas tank so ownes filling up with at least 1/4 tank all the time, these GMC trucks/cars are susceptible to water content build up in the tank causing spluttering and non starts when cold. Water is heavier than gas so lies at bottom of tank feeding the engine first and never mixing with gas. Remedy is to run tank to safe low limit and add water dissolver solution at next full fill up. Do this once a year in the winter when condensation/water build up is more likely. This is more common in colder & humid climates.

Just wanted to thank repairdog for the advice on the no start condition on the 2000 blazer. It turned out to be the cap and rotor causing the problem. Everything is fixed, and working fine! Thanks again!

Great! Glad you got it. Finding more and more aftermarket parts for the Blazers are not up to par and failing very fast so Delco ones are best or many are made by Standard Motors Corp so they have been holding up.

2000 Blazer Passlock Problem

I just bought a used 2000 Blazer TODAY ... and, it's sitting in a parking lot right now. My son, a very new driver, went to get the car while we were paying the bill at a restaurant ... and, the next thing I know, the SECURITY light is flashing and the car won't start.
The owner's manual led me to the Passlock section ...
I followed the instructions ... waited 10 minutes ... tried again ... but, no luck.
Any suggestions?
Thanks,
David in Detroit (CoachDave911 aol.com)
