starting issue

[lostjosh]

Ive done a motor swap about 7 months in my b2500 i put a 4.0 in it. It has been running just fine for a while until last week when i went to start it and got nothing. I have replaced the fuel pump so i have fuel pressure i bought a new coil pack still no spark. i replaced the crank positioning sensor. still nothing. im getting no spark at all. if i take the plug that connect to the coil pack and check for voltage i get 12v at the first wire and thats it. Im at a loss.

fuel cut off switch normally under passengers side carpet close too the firewall. Push in the red button see if that works. Worked for me bypassed it. no more problems.

Does it turn over? If it turns over does it have a fuel smell at the tail pipe or if you pull a plug?

Did you pull a plug and hold it against the block to see if you have a spark?
