No spark
No spark
I have a 92 ford ranger 3.0 i have replaced the coil, distributor, pickup coil, and ecm but i still don’t have spark it was running fine there was a little tick but that it and i started it up drove it about ten feet to the shed turned it off so i could work on the windshield washer fluid bc it was coming out and when i went to go start it up it almost did but then just stopped and hasn’t even gotten close to starting since i did a little investigation and found that i had zero spark and now i can make it spark with the pip wire at the ecm but it does spark when cranking
Welcome to the forum
Only way to test for spark on fuel injected vehicles is the 50/50 test
Spray gasoline, quick start(ether), carb cleaner, brake cleaner, ect..............into the intake
Try to start
If it it starts/fires then you have spark but no fuel from injectors
If it doesn't fire then no spark
50/50 instant results
If 50/50 has no start/fire then pull distributor cap, look a where the rotor is pointed, REMEMBER IT
Crank engine
Did rotor move?
If not the roll pin on the distributor drive gear is bad, or your timing chain broke
ECM?
1992 3.0l has a computer that runs the fuel injection, ECM?
1992 3.0l has a TFI module that runs spark, ECM?
TFI module on 1992 3.0l is on the rad support usually drivers side under battery, looks like this: https://i.ebayimg.com/images/g/yCoAA...wa/s-l1600.jpg
TFI module is the black part comes of of the Heat sink/cooling fins
