I have a problem that i hope someone can help me with.my ramcharger quit running and stalled on highway. had it towed home .It will not start,It is getting spark although I don't know how hot the spark is.I replaced the fuel pump,cap and rotor and coil. Someone told me to replace the ignition module. I cannot find one on this vehicle. Then someone told me if there is no ignition module on the firewall then I have a spark advance computer system that could be the problem. The truck has 167,000 miles on it.... I could use any help that someone could supply......... Thanks
