No Fuel No Spark.... Automatic Shutoff???
I have a 88 Jeep Wrangler 2.5L. It has no spark, and no fuel. I tested the ignition system and all is in working order. Then i found there was no fuel pressure. I talked to my buddy at work who is our local jeep guru. He said they have a automatic shut off that cuts off fuel and spark. So then he said check that. I checked both the relays with a multimeter and then ran a power source to them to check under voltage. Then we jumped the relay box and it still didn't work. So my questions are is the automatic shut off ran by the computer or by a switch. If it were to be the computer would i have to replace it. Or if there was a switch or some procedure to reset the computer?
Or any other possible diagnosis would be helpful
I still dont understand......
