Is there any theft codes? A theft code will kill the injector pulse.
Other than that it would be a wiring issue or the pcm has given up

Testimonial: "Thank you, I will give this info to the Tech."
the coil will get hot with running ,timing must be out put cam back as it should be ,it will not run any better with the cam advanced ,this is tech talk by part time weekend mechanics that know sweet all nothing .reset the timing to static for number one TDC ,firing order 153624 ,the only way a cam will give more rpm is if its designed to with a different cam lobe configuration not just moving it ,This will also cause the engine to use more petrol because it has no power at the low RPM range .These boy racer mags think they know it all with their cog boxes and harry moss add on goodies ,and fancy paint jobs .If you want a faster car get a ferrari or a jaguar XK ,and ignore these so called experts who are all talk to baffle people like you ,if they think they know it all just ask this question ?? is this engine adiabitic or isothermal ,if they cannot or will not answer this question then just call them a sunday mechanic .

SOURCE: I put a 97 engine
There are several thongs that could cause this. Have you checked the ignition module? The wore harnesses or ecu could be different. A number of sensors on the new engine could be bad or incorrect.

SOURCE: no injector pulse
what vehicle? injector pulse controlled by computer. the computer recieves a pulse from crank angle sensor, or distributor pick up, etc.
then controls injector pulse. Mass air flow on some vehicles determines spray pattern
