Cranks but no start. I have replaced coil n worked for 2days. I have power at coil, flash when cranked test light, power at control mod to pip. Spark out of coil to cap. 40* pressure at fuel rail. Won't start with starting fluid either. Any suggestions?

If it won't start with starting fluid and the engine sounds normal when you are cranking it over, you have lost spark. I have seen the ignition module go out on these trucks causing the problem you have described.

Please go over this guide as well:

Also have you run the codes?

Check out the images (below). Please let us know what happens.

Iv actually already did test light testing at control mode and checked fuses. I replaced the pip today and putting a control mod in later this evening. Which only leaves the condenser. Only other i can think of is if plugs fouled out after coil was put in and ran for 2 days.

Do you have spark when the engine will not run?

If you have spark will it run on starting fluid?
