Star98

I have a 1995 300 inline 6, OBD 1, and it has no spark at the plug. The distributer, plugs, and wires were replaced two years ago with roughly 200 miles put on the truck. Just replaced the coil tonight and still no spark. Over the weekend it started and ran just fine but now all it does I crank and crank.
Any suggestions would be a great help.

replace the ignition control module its located on the distributor and that should fix it thats the most common fix for no spark on that motor

well I found the ICM and replaced it with new one and still wont start!! what else could it be? everything is new!! and this ICM was on the firewall

well then lets try testing for power going to the coil and make sure your main power fuse for the ignition isnt blown if you have a haynes manual it will tell you how to test the power going into the coil in the trouble shooting section

The most common issue with this intermittent problem is the shield (bare wire) piercing the PIP wire. Look at TSB 95-15-11:

I had same issue with my '94 4.9L that would not start intermittently then later would magically start right up. This even continued after the 460 swap so I knew it was a harness issue. After opening up harness this is what I discovered - shield wire shorted to PIP wire:

UPDATE!!! I got spark now and got fuel spins over and still no start!!!

Is it even making an attempt to fire off? What's fuel pressure? Should be around 55 psi. Are the injectors pulsing?

injectors are plusing not sure on the fuel pressure but have fuel coming out of check valve
