Depending on miles and driving conditions, it could be the oxygen sensors. Some manufacturers recommendations suggest that the O2 sensors be replaced every 65,000 miles or so. To be certain, use a diagnostic code reader to find out what computer codes are stored. Borrow, rent or buy an OBDII (On Board Diagnostic Revision 2) code reader and follow the instructions. It will tell you what's wrong, and you won't have to guess.
Maybe you should service the engine soon. :P
Check for vacuum leaks.
Will a 1997 blazer what work on a 1999 blazer????? If your talking engine, transmission, or running gear than yes. It is all the same.
Key on Engine not running 55 - 61 psi. Engine running pressure should decrease 3-10 psi.
time for an oil change
wiil a 1999 blazer engine fit a 2002 blazer
60 to 66 psi. key on, engine off, pump running.
key on engine not running 58-64 psi engine running at idle pressure should drop by 3-10 psi
Have vehicle scanned to determine problem
I have a 1999 with 200,000 miles on it and still running strong.
use the dipstick when the engine is running to be certain:)
I've got 171k and still running like a champion
unhook battery or scan tool will do it
Inadequate fuel pressure. If that 2000 S10 Blazer has a 4.3 engine, it needs 61 to 66 psi (engine off with fuel pump running) to run properly.
The engine system urgent service indicator is a warning to turn the engine off immediately. Running the engine will result in severe damage.
Assuming this is the 4.3 L engine, 60 to 66 psi with fuel pump running, engine off.
I had my 200 blazer scanned an was told it was a bad fuel tank cap. I replaced it and the light is still on.
41-47 psi, engine off, fuel pump running.
There is a problem with the emmission system are transmission and the computer turns the engine light on to let you know there's a problem. Have engine scanned with a OBDII engine scanner.
You can get a diagnostic scanner to get your check engine light to turn off. It is best to take your car into a service center because the light is on because there is a problem with your car.Ê
If the engine is running, this is normal. If the engine is turned off and the pump continues to run all the time there is a problem, possibly a faulty fuel pump relay.
you need at least 50 psi to run and 55 or so to keep it running thats with cpi engine the others use less pressure and a different fuel pump....
The power of the engine of the Chevrolet blazer 8cyl 1968 is 435 hp
As long as the engine is running, it is normal for the fuel pump to run constantly.
Fuel pump running, engine off, 60 to 66 psi.
