Now the truck turns over but its keeps crankeing and crankeing. I have a new fuel pump on there that isnt that old. Its like its not getting fuel. Its just cranks and cranks and cranks. I checked to see if the choke closes and it does. Im drawing blanks right about now

I would check to see if you got any spark coming from the wires.

I use a spare spark plug and just pull one plug wire off and stick the spare spark plug into it. Crank the motor over and see if you got any spark. I have seen the coil in the HEI distributors go without any warning.

What year is your truck?

Is it carbed or fuel injected?

hope this helps :)

could it be the ignition control module ? Do the chevy have one?? Its is a GMC 3/4 ton carburated. Engine is a 350 I will pull a spark plug and check it

no spark at end of plug, thinsk its the module?

Right inside the top of your distributor cap is a coil type of thingy.
It is square and held in by 2-4 little 1/4 inch bolts. Make sure to reconnect the wires properly.

I would change that, they do go and they dont act funny first, they just go!

id start by changing that :)

its a 15 minute job :)

Top of your distributor cap inside there is a coil.

it is a square thingy held in by 4 - 1/4 screws.
when they go they give no warning at all, they just dont give spark anymore.
I just tryed to post this and my comp froze :)

One quick thing to check also is make sure the power wire is all the way on the coil.And on the back slot.The front slot is for a tach.If the clip is missing on the wire it will sometimes fall and not make connection.If you change the coil and still no spark.There is a module under the rotor.These do go bad and quick.I have been driving down the road and all of a sudden no more motor.Blazin:rasta:

Thanks guys, it turned out that the new rotor was destryoed under the cap, and the mdule was no good at all. My lock and tumbler is sticking a little, can I spary WD 40 in the key slot??

WD 40 is more of a rust loosener.
Ive been told not to use it as a lubricant, and when i used it on my bike chain, the chain rusted out.
I would recommend using graphite spray lubricant, or just plain old motor oil. :)

WD-40 actually removes lubricant. You should buy a can of that spray lubricant from the parts place. I use the prolong brand, and that stuff stays slick for a long time. WD-40 is great for quick fixes in a pinch, but it's best used to loosen rust and displace water, hence the name Water Displacement-trial #40.

NO! Dont ever use a liquid lube in a lock. Go to the local autoparts and get a tube of graphite. Only use dry lube in a lock unless you want it to get sticky every 6 months.
