I have a problem with my lumber hauler. Its an 87 Dodge Dakota with 52,000 miles. I bought it from my father who bought it new. It has an ignition problem. When it starts, it runs perfectly smooth with lots of power. It will run for several minutes and then just shut off, like you turned the key. Then it wont restart. It will crank, but wont start. Now when it starts, it runs for 30 seconds and shuts off. It has a new coil and all tune up parts. Like I said, when it runs, it runs perfectly. When it wont start, it has no secondary voltage at the coil. It has 12v at the coil. Ive narrowed it down to the Hall Effect pick up or the computer. It has a simple spark control computer. I know that the Hall Effect pick-up is cheaper than the computer, so thats where Ill go first, and thankfully I can get the computer, and its not too expensive $110. Anybody have any thoughts?
