No start prob

I have a 91 xj that isn't starting. No spark and the fuel pump isn't kicking on. I've checked the grounds, fuses, bat., cps, ballast resistor, fuel pump. It's not throwing any codes. Any help would be awesome. Thanks in advance

Re: No start prob

So the engine cranks over normally? Its the PCM which switches the ground for the fuel pump relay and the ignition coils. If power is available on the fuel pump relay, I would suspect the PCM. If no power on the fuel pump relay, then it could be the ignition switch.

Re: No start prob
