I have been unable to get the engine running this spring in my 77, with 3.2 engine upgrade. I am new to the car. Work I have done is- adjusted valves, and replaced the plug wires. My strobe now shows that cylinders are firing. So no gas. I jumped the fuel pump to run, but I still can't start the car. So, somewhere between fuel pump and cylinder, there is a problem resulting in no gas.
There must be a relay, in line fuse,or sensors thats gotten buggered up. Suggestions?

 

My 3.2 uses a DME relay. If it is bad, you will not be able to start it, even with the fuel pump jumped. Mine went out recently and I experienced the same symptoms.

 

try pulling an injector rail and see if they are shooting gas. I is pretty easy to see what to undo to get the rail loose then just pull on it and off it comes. If there is not gas try tapping on the injectors with a wrech, say a 17mm, and see if that frees them up.

I had to do the same on a few occasions.

Replace the DME Relay (as mentioned above) before you do anything else. If thats the culprit, you fix the issue for $30.
