About: 1999 Chevrolet Tahoe 4 Dr LT 4WD SUV
ECM -1 FUSE BLOWING
Hi, I own a 1999 chevy Tahoe with a 5.7 engine. Driving on the highway tuesday morning the truck went dead with no warning. I initialy thought it was the fuel pump but noticed the blown 20 amp ECM - 1 FUSE. I pulled the computer out and the fuse still blows, so I pulled the plug on the coil, and crank sensor and it is clear. I reconected them and it is still clear but won't start. Any help would be appreciated. Thanks in advance, Tony

I think your fuel pump actually is going and thats what may be blowing that fuse, also check your fuel filter and see if its plugged

The oil pressure switch is linked to your fuel pump fuse..Check that first then rule out your fuel pump.
