Question about 2000 Chevrolet Blazer
Replaced fuel pump, Ran fine a couple of hours. After parked overnight ,won't start , Two days later it magicly starts. Check fuel pressure running it's around 45 pounds.Runs great for another day and a half .Then next morning won't start. Put fuel pressure gauge back on .turn on key, It registers nothing,0 PS I've replaced fuel filter and relay,and fuse is still good. Maybe it wasn't the fuel pump in the first place. Anybody chime in at anytime. Thanks!
In our shop we have had the same problem before, it turned out to be a new defective fuel pump by Bosh, two bad ones in a row, try a ohm meter on the pump when it runs and when does not compare the numbers , if they are very different, try a new brand of pump.
