Hello, was wondering if anyone has experienced this type concern or may have further suggestions on what to look for. To sum it up vehicle had been running fine drove it on about an hour trip each way , when coming back vehicle started to buck and battery light flickered on then ran okay then vehicle cut off at a light, I was able to get it to restart drove it about 5 miles cut off again as I was entered my development. I pushed it to my drive way and tried junping it with jump box, multiple times, used another vehcile with cables multiple times, finally vehcile started and i pulled it up into the garage and parked it. The next morning started it up fine , went to drive it , vehicle cut off again and could not get it to restart. I finally towed it to my work last week , and had a tech check it out, there seems to be no spark. I replaced the ignition resistor and still no start, no spark, put a new Bosch coil, same thing, even to be safe replaced the battery all still exact same results. The tech states the distributor is giving off impulse and working.
I have power at the plus side of the coil with key on
I have checked the impulse coil with a meter on omes and it does 0 out when checking
i have checked and there are 12 v going into the ECU when you checked the connectors
I have checked there appears to 1 v of power going out of the ECu with key in on postion(when checking the harnesses that plug into the ECU).
The tech states all the fuses/relays are good
Fuel pump is working
Battery light does come on when going to start vehicle
I have been told a possible impulse coil could be the problem but my tech states it working and other think maybe the ECU is bad. Appreciate any help yall can give as this is becoming pretty frustrating ( and expensive, ha) as I said the wierd thig is the vehicle drove fine until the bucking started and it cut out. I have bene lucky I guess and this is the first real/weird problem I have had with the vehicle since owning it. Thanks
