I replaced the fuel pump due to it not working, now I still have a crank but no start. Replaced the ignition coil and ignition control module. Using my Snap-On Scanner I see an engine speed signal when cranking but still no start.

Hi,

Do me a favor. See if it starts for a couple of seconds using starting fluid. If it does, we know it's still a fuel-related issue. If there is no change, confirm there is spark at the plugs.

Here is a link that explains how:

Let me know what you find.

Take care,

Joe

So, I have fuel and I have power to the ignition module with the key on, but I do not have power to the ignition coil with the key on. What else should I look for? I have checked all fuses, but all are good.

Fixed It! Power wire for the coil was not making a good connection.
