Im a bit confused here 91 blazers dont have carburators stock and if it does then it has been modified other than that check to see if you have power getting to the fuel pump also question did you reinstall the ground strap to the fuel pump. check to see if you get power to the fuel pump relay. These are all questions I would Have done before pulling out a fuel pump. Note that you might want to have a friend help you cause if you turn the key to the on position the fuel pump cicuit is only energized by the computer for about 2 seconds
There are many oil seals in that vehicle, need to know which ones you changed.
It sounds like the Blazer has either jumped time or has a vacuum leak. Check the timing chain and tensioner as well as the vacuum system. If memory serves me right, that 81 Blazer still had a carburetor. The fuel filter may be plugged up. They are small and plug up easily. The fuel filter is located in the fuel inlet fitting at the carburetor. The fuel line nut takes a 5/8" wrench to remove it and the fuel filter housing nut takes a 1" wrench to remove it. Take note as to how the fuel filter came out and be sure to put the new one in the same way and don't over tighten it.
The oil filter has a remote location. Look underneath between the radiator and fan. If the black plastic shield is still their it has a access hole, marked filter.
And you still have a skip? Probably a bad injector.
Assuming this van is still carbureted, the fuel filter is located inside the fuel line fitting just as it enters the carburetor. It takes a 5/8" wrench to remove the fuel line and a 1" wrench to remove the fitting from the carburetor. Take note of the positioning of the filter so not to install the new one backwards.
check fuel pressure i think it should be 54-60psi if not high enouth its fuel pump
Strangest thing, I let the car sit for 3 weeks and went back to drive it, now its missing terribly. I changed wires, changed fuel filter, and its still missing terribly. I had a recent tune up done before this happened. Would appreciate and feedback anyone can give about this
The cabin air filter can not cause a rough idle. It only filters the air for the ac/heater.
i have to same problem with my sierra ive changed the filter and it still leaks, i was told that its the oil filter adapter you can get one at autozone for about $20
Check the brake light switch.
check that the O ring was replaced when oil filter was changed. id O ring is good and filter is tight, and housing still leaking, replace filter housing
Have you changed the air filter too?
carb. adjustment, fuel filter or the engine is shot.
was fuel filter replaced
Replace the fuel filter and if it still acts up have the fuel pressure tested. It should have 41 to 47 psi.
Change the fluid and the trans filter; a dirty trans filter can cause this.
it is losing its prime... i have the same problem right now and i have cleaned the carburetor, changed the gas and spark plug and changed the air filter. The only thing that i can think of is that there is something wrong with the priming bulb or the gas cap is hindering the air flow... still trying to repair....
dis connect battery for 2 min. then reconnect and try to start does it even try to start
check the alternator, ignition coil. or even see what the charge at the battery is.
need help figuring out what else to try to fix my leaf blower! i have replaced the spark plug and cleaned the filter, but it still won't start, like it is not getting fire to the plug! also, i put fuel directly into carburetor. any help would be appreciated. thanks, ed
You may have a bad fuel injector. Try to single out which cylinder is dead, then remove that spark plug, if the plug is clean and dry you have a faulty fuel injector.
No, it still has a distributor.
Was that the only code that caused you to replace it? Do you have it close enough to sense again.
