hi does it crank over ???? tell me more of condition
cranks fine,gas pump is working gas to tbi none from injectors.no fire from coil,12 volts from 2 wire connector from coil to dist. replaced coil anyway and had the ignition module tested,tested it 3 times module is good.tested pick up coil resistance, good at 850 ohms.guess I'll just start all over and test all sensors that I can,feel like something has locked it out but like I said before,,, no code... thanks for any help ( will have to wait till after Christmas) Merry Christmas!!
