So i have a customer that needed a new engine in his lmm. I put a lbz in it that I had and got it running. It was running rough. So i left it run for a few minutes and shut it off. I started it right back up and it ran smooth. Now it won't start back up. It cranks like it wants to kind of fire but doesn't. I checked both reluctor wheels and everything. I have everything i need to make it run according to the scanner. There aren't any trouble codes. I am at a loss on this. If you have engine grounds that are bad, what are the symptoms? Thanks
LMM: No start
- Thread starter gmac32
- Start date
Just cleaned all the grounds. It acts like it hits on a cylinder but it is like it is not commanding any fuel. I don't get any smoke out of the exhaust. It will run on ether and sounds fine. I am clueless right now
So you disconnect the glow plugs. Did you plug the cam and crank sensors in backwards, did you verify you’re getting a signal from them.
Yes to all. I got it to run today but it really rough. The balance rates are all over the place. I think the injectors may be sticky from sitting.
