I have a 2001 4.2l Chev Blazer bought in from Japan 12000ks[7.5mls] and have had bad bad problems with starting like it wants to start but hydraulics and splutters. It has cost me in excess of $3000 and a new starter motor in fixit charges and eventually found the sensor on crankshaft replaced seemed to cure it. Some months later it refused to start again same symptoms..tow truck to GM agent and top thingy like a distributor replaced. Eventually diagnosed that the sensor on crankshaft MUST be set by GM dealer otherwise the problem will recure. At the same time get the factory transmission upgrade. Good luck.

have changed fuel pump thinking that was the problem but found out that i have no spark. checked into it a little more and have no juice going to 5 fuses in the fuse box. checked fusable links (5 of them on drivers side and one at battery) and are good. could this be ignition switch or computer?

  hey guys,
I have a 00 Blazer again with the 4.3L w/ 125k mi. Been having problems with starting it. Seems like its not getting fuel. I shoot a little cleaner into the throttle body in order to get it to start but that dosen't always work. I've checked the fuel pressure at the rail and its sitting at 65 with the key on. Its slowely geting worse as the days go on. I talked to a mechanic and he said it might be the spider injector or the regulator. I do a lot of my own work but never got into the engine itself. Anyone had this problem before and know how to fix it? The mechanic told me if its the injectors it'll run about $450. Is this something I can do in my driveway? and what it would cost?

I have had that problem with my 98 jimmy and it was the fuel pressure regulator, If I were you I would do the whole assembly. The job is nothing at all. basic tools. Look on this site to find instructions, it is easy trust me.

My blazer died and won't restart. I've tested fuel,it's ok. I've replaced the coil,dist.cap and rotor button,and the shaft sensor; now all it is doing is blowing the ECM fuse every time I turn the switch on. Please help!

This could be a real stretch but I had a similar problem where I had trouble getting the truck to start every few days where I had to turn the key a couple times, then would stutter when first going, a couple times just stalled out. Drove myself nuts with hoses, fuel pressure etc.
 
Had a rusted battery terminal screw. It was being shaken when driving, caused the battery not to charge properly when driving. An easy test is to jiggle each wire separately(obviously do not create a connection with yourself and the car). You will hear the power go on and off.
 
Again probably not it but was listed as one of the first things to check and I ignored it because had one of those duralast batteries
