If it will not hit with spraying starting fluid, that indicates that you have a no fire condition. Start at the spark plugs and work your way in from there. Wires, coil, crank trigger, fuse.

Hi there, I'm not sure if you're still looking, but I found your car's obd if you're still looking for it: http://bit.ly/16kzNAF

Yes, it is a mechanical oil pump. Just for peace of mind, you could have the oil pressure checked. A mechanic shop could do it real easy-you remove the oil pressure sensor or sending unit from the engine block and hook up a "mechanical oil pressure gauge", then run the engine with gauge attached and check pressure against the specs for your model- it is a specified pressure at a specified engine rpm. I f oil pressure is within specs, I can't imagine anything else about the pump that could cause that noise. It is a compact unit with a couple of heavy internal gears.

If your mechanic didn't think it was a bearing or rod either, you should be safe there. He would know the sound of a rod bearing or mechanical problem like that, and if it is different from your sound. Beyond that and the oil pump, I just don't have any ideas.
Hope you find it, good luck.

My air pressure is low in 2003 Chevy express 3500 , I change the blower motor and still have the same problem ....the ones on the passenger side blows a little harder then the driver side I ready need to fix this problem cause it is hot in Texas

Did you check for voltage at the applicable fuse/s? Use a testlight and check for voltage at the fuse circuit with key on. The gauges usually get voltage feed from the ignition switch, key on.


I haven't looked at your wiring yet, you may have to check feed to and from ignition switch.

Found these two fuses for instrument cluster. One is hot all the time, the other goes hot with the key on. If voltage and ground for the instrument cluster are good, something else is wrong.

low on freon

you should have a tag label on the engine compartment

bad gasoline

gauge light means there is a gauge that is not working

it goes

Cab of truck
8 7
6 5
4 3
2 1
Fan (front of truck) For the V8

So, I would guess from this the drivers side would be odd bank, or would that make to much sense? Hopefully this helps!

WELL I WOULD TEST CAM SENSOR OR CRANK SENSOR THE CAM SENSOR CONTROLLS SPARK AND FUEL SIGNAL HOPE THIS LEADS YOU SOME WHERE

Check the source vacuum from the engine to the control head.

15A LTR fuse 30 in the underhood fuse block

Check TPS sensor[RPM]
