Changed fuel pressure regulator had to remove distributor cause clip that holds fuel lines in flew now truck cranks, but does not fire over, It gets gas got spark. At a loss as to what could be wrong as we have reset the distributor multiple times thinking we did not get in right position, but to no avail.

The distributor cap is a little confusing as ti which cylinder the rotor is pointing to. You have to bring the engine up to TDC on #1 on the compression stroke and then align these marks.

If you have the flat distributor cap, they definitely do not line up on the outside. You have to look at the inside of the cap to find #1.

If you have a non OBD2 system, you will have the old style distributor and that one should be easy to install.

It s the vertical style my buddy who is certified said something about being an adjustable distributor should the fuel regulator needed set before install it came with a bit to do so, but we assumed it should be set close enough to run on out of the package.

The last picture looks like mine. I cannot tell if it has two plugs like mine or not, but the rest seems right.

You need to go back to basics and test fuel pressure and spark. This system will not run under 55PSI of fuel pressure.

We have spark just does not seem that it is firing fast enough or maybe my firing order different and I cannot check fuel pressure. Do not have access to a gauge to do it.

Unfortunately you are just spinning your wheels if you do not have a fuel pressure gauge. Fuel pressure is critical on this engine.

Fuel pressure is spot-on moving on to replacing the distributor.

Your fuel pressure test does not make any sense. The spec is 58 to 64 and it will ever exceed that spec because the regulator bypasses at 64 with the engine off.
