I have no Check Engine Light! The FSM tells me how to test the ECU unit with a multi meter. but the normal operation should have the light engage when I turn the key and off after I start it. I have had the ECU unit rebuilt. but I have not retested the new part. I guess I will do that next. but first let me bring you up to speed. i have just installed a new block and tried to button up all of the electricals. There is no check engine light. I have looked at the fuses they are good or at least they look good. I have checked the big relay fuses in the engine bay. relays intact and showing 0 ohms resistance. I have pulled and switched the bulbs in the instrument cluster. the bulbs are good. charged the battery and tested the voltage it holds 12.8v or so. the fuel tank has 1/2 full fuel. the ignition fires. spark comes through the coil into the distributor down the lines into new plugs. timing has been set and double checked. my rig is A/T and it will crank in P or N but not the drive gears. FSM testing of the Ignition coil seems like there is low voltage if testing from the Positive side to the hole in the middle. It cranks but not as strong as I would like. it fires up on the first turn of the key but does not run. second try it fires and dies. third try it does not want to fire again. could I have a bad fuel pump or relay? If the Check Engine light does not engage is still should run though right? just poorly? if I could get the ECU to talk to me I could fix the physical problems but electricity is my nemesis. Please help me and flipper to get moving again! it is the season to explore and visit!
