1985 chevy blazer s10, replaced mechanical fuel pump, still not gettin fuel to carberator


I have a 1984 S-10 Blazer since it was new
almost 29 years ago

Explain how a new fuel pump doesn't work

I only had that once on my 1965 corvette
A new pump had been assembled with the
diaphragm outside on a couple holes,a quick fix

You must have fuel to the carb & thus you need
to take the carb apart & work on that

So far I found that NAPA is the only source for
a carb kit

97 chevy blazer w/ 4.3 won't start unless i pour full directly into it....what is causing this. was driving and it just stalled ...fires but won't turn over completely


if you can put fuel in throttle body and it runs. then it is not getting any fuel. check your fuel pump fuse and the relay, if ok, then you may have a bad fuel pump or a plugged up fuel filter. check filter and fuses first. good-day !!

My chevy blazer is turning over but it won't start even when I put gas in the carberator.


You don't have a carberator on it, it's fuel injected. Id try spraying carb cleaner in the throttle while you have someone turn it over. If it fires up for a few seconds then dies then you might have a fuel pump problem or fuel filter clogged. If it still doesnt fire up then check if you have spark, if no spark see if your crank sensor is good and if your coil is getting power. If your coil is not getting power you might have a crank sensor problem. Try this and let me know if it helps.

1997 chevy s10 blazerdash wont light up when key


the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!

Have replaced fuel pump, relay & fuel filter.


have you checked to see if you have a bad came or lifter. that would make it backfire. if it kind of spits fuel it maybe cam. if it throws fire than it could be timing like a bad chain.

1986 Chevy s10 won't start


small gas engines 101. gas+air+compression+spark=vrrrrrrroooooommmm
i doubt its a fuse. make sure all cylinder have good spark. try and run some seafoam through the gas tank and i would look at the timing - im not sure how you know the timing didnt skip but that sounds like your problem.
