I`ve replaced the plug wires,cap, rollers, end distributor, ignition coil, ignition module, ecm, ignition switch, and ecm relay.
the distributor want fire, fuel ingectors want fire, both sides of the ignition coil are hot when the key is on. distributor wire is hot when the key is on, the ignition module wires are hot when the key is on.
seem like to me something is not sending a signal to the ecm.
i checked my ground seems like the ground is o.k.
The weirdest thing about it that i changed the distributor and the truck did crank, but 2 cylinders would not hit.
Then put another new distributor in it, and the vehicle runs good.
Couple weeks later it starts slow, then every now and then it will shut down or after running itll set for a few minutes and be hard to start or no start.
Sometimes let it set a few hours it will start.
When the truck cranks it runs good, but right now it want crank.
anyone can help?
