Hard starting

Postby microsvc » Wed Oct 21, 2015 1:34 pm

My 2001 4.3 Crew Cab is hard to start only if the engine is already warm. I have to crank it for many seconds then it starts and it runs good. Sometimes during the cranking, it backfires.
I can't afford to have it looked at right now and am hoping to get some guidance here for now so I can maybe fix it myself. Thanks!

Sounds to me like it is electrical in the distributor. Ignition module. Starts good when cold and when it gets warm a component or wire opens up due to the heat thereby causes your problem.

I would sure look into the electrics part first.

Good luck and keep us posted

Sorry for the long delay in responding. I got two bad ICMs, and the third was an OEM part. It did not fix the problem. Suggestions...

Basics. Ignition , fuel , air.
Distributor, plugs wires coil.
Fuel, Fuel filter, pump, injectors.
Air fliter, IAC valve, MAFS, EGR valve, throttle blade, vacuum lines, manifold leaks.

All suspects.

Yeah, I'm thinking mostly ignition, but any of the other items can be suspects.
