Do you hear the fuel pump come on for 2 seconds when the key is first turned on?
.
.
Do you know what the fuel pressure is?
.
Have you checked for spark at the plugs?
.
Does the engine have good compression?
.
Customer: replied 2 years ago.
Yes I can hear the fuel pump turning on and I have fuel up to my fuel/water separator. The fuel is pumping. I am not getting any spark from the plugs. I can not figure out why.
Expert:  Super mechanic replied 2 years ago.
Assuming that the rotor is turning when the engine is cranking. Have you checked the ignition power transistor, (module)? Also, power to it?
.
Here is a link to the test for it.

Yes I have power come into my ignition coil and power going out. I have power to my distributor but no fire coming out to my plugs.
Expert:  Super mechanic replied 2 years ago.
That could be the power transistor but you will want to make sure that the coil is good as well as the crank angle sensor. Here is a link to some more tests that can be done to see. Of course that the rotor is turning and it's not just the timing belt.
