Well, I found another ignition control module and swapped it in just to test. The car fired right up on the first crank! I let it run, turned it off. It started again two more times. It was running, but sort of rough like the timing was off. That is when I noticed that the distributor cap had rotate...

Hmm, I have neither of those tools. Nor have I used an oscilloscope since high school physics! Automotive logic probes are $10 -20. They are just old fashion trouble lights with LEDs and current limiting resistors instead of incandescent bulbs. The lower current draw of the LEDs is what make them c...

What do you mean by firing pulse? I just went out and checked. I have 12.2volts on pin#1 with the key in the on position. Pin #1 of the ECM should be 100% grounded with engine not running or cranking. Pin #1 Opens/Floats/ goes high to fire the coil when the engine is cranking or running. When crank...

Crank no start. This time around I have no spark. Been running fine lately, then today would not start. Are you getting a firing pulse on ECM pin# 1 (Gray wire)?

Six and a half years later-running into similar issue. Crank no start. This time around I have no spark. Been running fine lately, then today would not start. New battery, new plugs, newish rotor and cap. I can hear the fuel pump when I jump it at the fuse panel and the relay. Coil resistance is wit...

Hello Group. I need some advice tracking down an overheating issue. I had a slow coolant leak at the thermostat housing and at the top of the water pump. It had been leaking for some time, performance was fine and I kept the coolant topped up until I could get to it. That time was yesterday. I repla...

Undertook the infamous blower motor replacement today :evil: . Dis-assembly and replacement went fine following the lead of many others. However, when I made the connections and turned on the fan I only get one setting-high. This leads me to believe that there is a problem with the resistor. The mot...

Hey MM, I have yet to fix mine, just dealt with it. I have been focusing my energy (money) on other things. A few years ago I did quite a bit of looking around for the latch mechanism parts and they were either non existent or cost prohibitive. The link could probably be made from some thin gauge ro...

Turned out to be a faulty ignition control module. Local pick a part had one for $30 so just swapped it out instead of trying to solder/repair the old one. Ended up replacing the coil as well, the high voltage resistance was higher than spec. Started right up!

The ignition module connector feels solid and the car did not start while pushing it in. It behaved the same as before. I checked the vacuum hose off the fuel pressure regulator and could smell gas. I did not have time to pull the return line and check that. Would that indicate a bad regulator? Woul...
