[jeep12827]

Ok well my problem is my fuel pump is not making the normal hum, and my fuel pumprelay is making a ticking noise.. I have no spark, replaced the coil but still no spark.. we bypassed my ticking relay whihc made my pump come on normal and i have the right psi at my fuel rail but still no spark.. it seems as if alot of people have been having this problem but im just curious does this sound like a CPS? i have checkedit with the voltmeter and it says its good but iv heard alot of the time it can be tricky and read good but not be.. can someone please help?? do you think its a cps? oh and my jeep is an 87 cherokee pioneer 4.0 litre 5 speed manual trans
