I have a 1992 camaro with TPI and 5.7 engine. I changed out the injectors and installed Arizona speed and marine runners. .In the process I had to take off and put back on the valve covers. Now the car will not start, Car cranks fine. I have no spark. I have checked and found no connections that I may have knocked lose. The coil has power.. I tried a known good ignition control module. but still no start. Fuel pressure gauge attached to the fuel rail shows 40 PSI.. The tach shows no movement while cranking on the dash and also on the laptop attached to the car. - I don't know if it should. The coil tested good off the car. What else might have happened? Thanks for any ideas.

 

Sounds like the low-voltage, signal-level, connector out of the distributor, is not connected.

Pretty straightforward overall. Check your work.
