i have a 1999 c3500, 5.7 4l80e
I was messing around in the fuse box the other day and accidentally pulled the ecm-1 fuse and it shut the truck down. Ever since I haven’t been able to get the truck to start again. When I first crank it she tries to start but as soon as it does it dies again
Was looking into a few things and I know I’m getting spark to the plugs, and it will stay running on starting fluid.
It’s got a whole new spider injection system along with fuel pump and everything. I’m not sure what’s causing the injectors to not fire properly. I used a NOID light and as I crank it sends power fine but once it starts the injector pulse is very intermittent. Any ideas?
