Did you replace the crankshaft sensor? And pick up in the distributor?


Crank or cam sensors will sometime not work when hot.

Ok so I went to the auto parts store in my area none of them offer a cam or crank shaft sensor for my truck I was just looking over the engine to see if I can find cam or crank shaft sensor and I couldn't find anything resembling one what I did find was a broken wire off the knock sensor could that cause the problem


It might.computer needs a lot of information to run need all sensors.
