please help, tach stops then C.E.L.
« on: April 23, 2019, 11:38:18 pm »
I have a 99 dodge 24 valve cummins 1 ton, I just purchased the truck, it seems to run ok, maybe a little sluggish. when I start it the tach comes on and works for 5 seconds then it stops working and the CEL comes on. I can wait about 10 minunites and go back and it will do it all again!  I have replaced the crank position sensor and camshaft sensor, checked every ground I could find, cleaned connections, I am lost here! I have a cheap code reader, but cant retrieve any codes with it,  and the key trick does not pull codes either. it never cuts out or dies on me, just the tach and cel.  and it's like it resets itself every time I kill it.  any ideas?
