It died driving down the road and now its not firing

Check the Crank Angel Sensor

could be out of flue

tune it up n check the timing belt

I have 94 s 10..4.3 v6. it does the same thing have replaced fuel pump and filter,ignition module,cap rotor plugs wires,coil,ground strap...driving down the road jus dies like the key got shut off....for a while when troubleshooting through the parts you could get it to restart.....now when it dies it cranks really hard when trying to restart..ive checked the timeing its fine....if i wait a few min it will usually start...sometimes it will show a check engine light sometimes not......never know when it will happen sometimes jus down the the road from the house sometimes 100miles down the road......sometimes three times in a mile sometimes not for weeks at a time..Wtf...Im ready to shoot it like a lame horse....its a shame too its a sharp lil truck thats a two owner and never spent a night outside in its life...i knew the original owner ...i bought it with 90,000 on it it only has 148,000 now and still looks like new...

Have you checked cam timing?If it has jumped a tooth or two it will not start.

probably the crank sensor

Are you getting a spark from the coil wire ?
Do you have voltage going to the coil and a ground signal from the computer ?

Could be a problem with your high pressure oil system that fires the injectors. As your oil heats up it gets thinner and less oil pressure is available to fire the injectors. Black smoke is a sign of over fueling. Is it chipped? If so remove the programmer and see if the problem goes away.

ignition control module needs to be tested

i may talk out of order but check the crank sensor i had one that acted that way.
