Hi I have a 2003 dodge ram 1500 and we'll I bought a combustion test kit cause I just wanted to test the combustion of my cylinders well the tests came up ok every one of them was either 145 or 150 and I put everything back how it was but now my engine won't start. Before I started the test I pulled the ignition run fuse and the fuel pump fuse . It was running ok before I did this what could be wrong? Any knowledge would help alot.

 

Combustion or compression test? Did you put all the wires back right? I use clothes pins with numbers on them for the plug wires and paper tags on the other connections. Do you have any codes in the computer?

 

Yeah that sounds like a compression test. So all 16 plugs and coils properly back in place as well as wires? Put the fuses back in properly? Haven't popped any others?

 

It may not be a hemi motor and if it were you would need only remove 8 spark plugs. Take the plugs back out and see if you are fuel to the plugs or the plugs foul out with gasoline. Also recheck your fuse box with a test light.
