tjbuggie Posted November 19, 2016 Share Posted November 19, 2016 So I just picked up an 88 Comanche from a guy I work with, and the problem I am having is when you go to start it, it will run up to about 2k RPM for a second and then die, hit the key again and same thing. The guy I bought it from said it ran good, but has been sitting for about a year. My question is where should I start looking?? Link to comment Share on other sites More sharing options...
gogmorgo Posted November 19, 2016 Share Posted November 19, 2016 Sounds like the fuel pump ballast resistor circuit is having problems? Try bypassing the ballast resistor. There could also be rodent damage to the wires if it's been sitting. It's also a good idea to go over Cruiser's tips. www.cruiser54.com Link to comment Share on other sites More sharing options...
