i just bought a 98 cherokee sport 4.0 4x4 auto. it has been sitting for 6 monthes. it was started and ran fine 2 months ago. now it will not start. lots of problems, i'll start from the begining.
dead batery-installed new one.
engine won't turn over and reverse lights won't come on.- i figured its the neutral/reverse safty switch, so i pulled the relay in the engine bay and used a wire to jump it and the engine cranks perfectly.
now the kicker: no spark- (i have another 98 cherokee that runs fine, so the following parts came off it to get this one running) replaced the crank position sensor, no change. replaced the cam position sensor, no change. checked voltage coming to cam sensor, no voltage at any of the 3 wires. checked wires going to coil, no voltage in either one, no pulsing ground signal on either one. all wires were checked with ignition on and with engine cranking and not cranking.
not sure where to go next? computer? ignition switch?
there is no "check engine" light
turning the key to "on" seems to make all the other electronics work properly.
power door locks do not work at all
any ideas greatly appriciated.
