Phil Mcrack Posted August 12, 2021 Report Share Posted August 12, 2021 I am ripping my hair out trying to figure out what my problem is. Motor is fresh built will crank and crank and sounds like it is almost to the point of starting but it doesn't. Ive physically pulled the fuel rail to see if the injectors are firing and all 4 are, and not leaking. I have also done a compression and is good across all 4. also pulled all the plugs and all 4 are getting spark. When cranking the motor will sometimes give out a really really loud pop. Also black smoke will come out of the exhaust when cranking. I've also tried squirting starter fluid in but it ignites in the intake manifold and pops loud... Also the plugs are wet when pulled after cranking.Troubleshooting I have done. New spark plugs Brand new cas New ignition chip All fuses in engine bay are good Checked all grounds Put cas in 180 out just to see and no difference Prob some other stuff I'm missing I really would appreciate any help you guys can give me it's been weeks and I just want to drive it. Thanks. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted August 12, 2021 Report Share Posted August 12, 2021 Can you attach a PCLink Log of you trying to start it and if possible a trigger scope when it is cranking please Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted August 12, 2021 Report Share Posted August 12, 2021 If you press F12 and go to the trigger tab do trig 1 and 2 both go green while trying to crank. Quote Link to comment Share on other sites More sharing options...
