1994 Chrysler New Yorker Front Wheel Drive Automatic
My local mechanic advised a bad computer, I replaced it.A friend advised crank and cam sensors, I replaced them. Auto parts guy suggested bad wiring grounds, I dont know were to look, chiltons wiring diagram doesnt say were ther located. When it was put on the scanner and started it didnt send any trouble codes. When it's on the scanner and doesnt start (99%) of the time now it doesnt send any message from the computer. Any ideas?
If it cranks good but won't start, have helper crank it while you visually check for spark at the plugs. You can use known good spark plug or spark tester, then just pull a plug wire, stick tester in boot, ground tester to metal part of engine, engine cranking, watch for spark. If you have spark everywhere, use a gage and check fuel pressure.
You should be able to check mil codes, yourself, anything?
