98 Chevy Blazer wont start after replacing heads


Make sure you have power to the fuel pump. On this model you should hear a quiet high pitched mosquito in your ear sound when you have all the lights on the dash panel just before you turnover the engine. If push comes to shove, take the fuel pump out, keep the power on it and run it through a bucket to see if you can at least pump water through it. Make sure you let it dry out all the way though before placing back in the tank.

I have a 99 chevy blazer won't start but will turn


You may have a fuel pressure problem or the secuirty system has locked you out for some reason due to a false signal or failed part. Do you have any electronic engine control codes? Is the Security light on in the instrument cluster and fishing when you try to start the truck? To check the fuel issue get a can of spray starting fluid from the auto parts store or any hardware store and spray it into the air intake of the engine while someone cranks the engine, if it starts you may have a defective fuel pump, the pump is located inside the fuel tank, the fuel tank must be removed to access and replace the pump.

When i fuel up 88 blazer, there is pressure building in the gas tank, ( it hisses when i open the cap) and when driving down the road it seems to be very sluggish and sometimes even dies... but this seems...


the pressure in the fuel tanks supposed to be there,your fuel pump,,,pumps 180lbs of pressure to the engine all the time.your engine requires it. so if you do not hear that pressure when you remove the gas cap,you do have a problem. but it does sound like you have a possible fuel injector or maybe 2 fuel injectors clogging.simple to give you solution.add lucas fuel injector cleaner to your fuel tank.a clogged fuel injector will seem like an engine misfire also,just because fuel bulds in the cylinder at times,then the spark plug fires and then BOOM the engine misses while in motion. sound familiar? the lucas costs $5.00 and will treat 25 gallons of fuel. try this,and please let me know if this helps!!

Where would the fuel filter be on a 2000 chevy trail blazer please ! ! ! :)


The fuel filter is on the drivers side frame rail and is a high pressure system, so you should attempt to depressurize it. Take the fuel cap off. Pull fuse for the fuel pump. Start engine, let engine die. There will still be a little pressure in the line and certainly fuel in the filter and line. I had to remove the skid plate to get to the filter, there was a hand hole, but not for my hand to work in effectively. The clips are real easy to remove with some pliers. Use a towel or rag to remove the fuel lines and protect your self from the fuel. If your new filter doesnt have the little plastic doo-hickies (technical term) on the nozzles you will need to get them off of the old on, just pull them off gently, dont break them. Put the fuel lines back on noting the flow arrow on the filter. Replace holding strap and skid plates as applicable. Replace fuel cap and fuse. Start engine, let idle a minute or so. Drive around the block a time or two and enjoy. Repeat procedure every 30,000 miles (I think that is the manual periodicity).
