Customer Question

My 2001 S-10 with a 4.3 engine won't start

Hello jacustomer, how many revolutions do you typically get out of it?
Customer: replied 5 years ago.
Right now it keeps cranking and trying to start. I wear down the battery so I have to recharge it.
Expert:  BOBBYSS replied 5 years ago.
Have you noticed if the security light is on or flashing when cranking the engine? Did the engine die while you were driving?
Customer: replied 5 years ago.
Security light is not on during cranking. The engine never died while driving but last week before all this started, after a short trip to the gym, when I came out and started my truck it didn't feel right, it was running rough as if it was only running on 4 or 5 cylinders. On my way home it cleared up. After it sat overnight the next day it wouldn't start.

the first thing to do here is to check the fuel pressure,,these must have no less than 60psi at all times,even while turning the starter......the fuel pump may be weak and need replaced,,,if the fuel pressure check out,,,,check for spark on the plug wires,if you have no spark,remove and test the ignition module[most auto parts stores will do this for free]...if it does have a spark,,the problem may be the distributer cap,it is common for these to burn up on the inside,even if they look new and you do have a spark...if you end up replacing the cap,it is a good idea to do a complete tune up all at wplugs,wires,cap and rotor
