When adjusting the valves on an ISC does one bar engine over the usual way clockwise. Or are we suppose to go counter clock wise.
Expert:  Wayne replied 1 year ago.

Hi I'm Wayne

I will help you with this

you bar the engine over in normal engine rotation CW

are you sure you had the gear timing all aligned when cam was installed

and when going from TDC, and 1 full turn it will be on TDC again

Customer: replied 1 year ago.
I pulled the cover off and rechecked the gears all lined up. I have followed directions per Cummins and when its time to adjust valves I can go 180 and adjust remaining valves. Is that correct.
Expert:  Wayne replied 1 year ago.

Its getting fuel to the fuel rail and fuel lines. I pulled the injectors and there is fuel on the injectors. Should I replace the high pressure connectors for better fuel pressure.
Expert:  Wayne replied 1 year ago.

Hi

What is your fuel pressure

need 4500-5000 to fire injectors

yes check and unplug injectors connectors

Customer: replied 1 year ago.
Any other suggestions on making sure its in time other than gears. Could I have missed something when putting cam back in. This is my first no start in 30 years. its also my first ISC. What a pain this one has been lol.

Don't have fuel pressure gauge but it appears by sight to be sluggish in pressure.

The pump was pulled and checked half a$$ by someone that didn't have a clue. He put a gear on it and turned it that's about all. Is there any way the pump go out of time.
