Re: 2000 Chevy Blazer won't start / low fuel pressure [mperu99]
Written by: freakist on Nov 15, 2011 6:55:18 PM
I had a circumstance once wherein I had a short inside the oil pressure sender, and this kept blowing the fuse on the ecm "b" bus, which killed the fuel pump relay. whatever you do, don't try putting in larger fuses to get it to run longer if you find the ecm fuses keep blowing. it may require pulling each sensor and bench testing it, but too many amps through the ...

FIXED!! - I originally put a pressure gauge and it was reading 48lbs, i thought that was enough, however it was not.. I replaced the pump and the fuel filter and now i got 60 lbs (key on - not started) 54 lbs (running) Now it starts no issues. You should be near 61 lbs (key on - not started) for proper starting. 55 - 61 lbs for starting, the higher ... Read More

Re: 2000 chevy blazer fuel pressure switch [racer4x4]
Written by: freakist on Sep 29, 2011 7:40:13 AM
Having a failing fuel pump is likely the cause of this, The pump is required to send fuel at around 58-62 psi (on mine) and when the engine isn't running, the battery must supply power to pump up this pressure, a worn set of bearings or anything else that causes the pump to be slightly harder than normal to turn will require more voltage than the battery can deliver at startup, ...

Replace the fuel pump relay and/or the fuel pressure regulator. Replace the relay first and if that does not fix the problem, replace the fuel pressure regulator. Fuel Pressure Relay: ACDelco D1786C (GM 19116657) $8.10 $15.80 MSRP Fuel Pressure Regulator: ACDelco 21-72251 (GM 19106768) $66.00 $126.00 MSRP

Sure. Things like a loose fuse holder. Causes an increase in contact resistance, and more heat. Fuses are blown by heat, whether caused by excess current, ambient temperature, or high resistance in the fuse holder itself. Not uncommon to see a fuse blow when a cheap inline holder is used on a high current circuit. Sometimes, if the fuse is rated high enough, the holder itself will melt before the fuse ... Read More

No, the heat underhood alone will not pop the fuse. But the high underhood temps combined with a fuse element heated by it's rated current can definitely blow a fuse. Electric current is what causes the temperature to rise in the fuse element. When it gets hot enough, it melts and opens. The same issue can occur with automatic resetting circuit breakers, such as on some headlamp circuits. The breaker will ... Read More

RW2 thank you for the nice words. I have been a mechanic for Ford motor company and General motors for 38 years. I am not a genius but heat from air temperature rise will not blow or (pop) a fuse.

Glad it was just the fuse. One thing that folks don't often realize is that it isn't the electricity per se that pops the fuse. The fuse has a specific (very low) resistance, and the more current that goes through, the hotter it gets. A short circuit will cause a very fast rise in temperature in the fuse element, and 'pop goes the fuse'. I mention this because in intense summer ... Read More

I do know the hatch,door locks and mirrors are on the same circuit. If you have checked the accesory fuse(Ibelieve that is the one), It would be the relay. The problems you have with those is that they draw a lot of power to operate. That's why there is a relay also and not just a fuse. If I remove the power accesory fuse,those same things do not work at all. ... Read More

Well, I'm not much good at this stuff, but my driver's side window switch carbons up every couple of years on my van. When the switch quits, you don't hear the motor at all.
