Help! 1998 Gmc K3500 Will Not Start

[abradford]

Hello all. I need help badly. My 98 K3500 CC DRW quit running a week ago. It turns over but will not catch. No Codes show up. So far i have replaced wires, plugs, distributor cap and rotor, and electronic ignition switch. I have 60 psi fuel pressure on the rail. Getting ready to replace crankshaft position sensor. Any ideas would be greatly appreciated.

is it a 454? i had an issue like that on my 98 a long time ago, ended up removing the fuse box under the hood, found a large gauge wire (red in color) that was piched in the mount, don`t know what it was for, but after repairing it its been running for 3+ years since no issues. just an idea, easy to check.

 

other then that have a good going over on all the electrical, connectors, looms and grounds.
