Some info: New line from tank up to fuel filter. new fuel filter. but the other lines i did not replace. 95k miles ive ran several tanks of gas with lucas fuel additive after buying it from a guy who had it sitting for a little while.

I had this same problem on my 1996 jimmy 4.3L 155k miles

I now have a 2000 2Dr Blazer 4x4 Zr2 5 Speed 4.3L V6 The engine is stone cold and i go to start it, it fires right up. when at full running temp it takes a while cranking then finally puts up to idle. If i give it gas it starts up a little better but still takes a while. I can flip the key to run let the fuel pump get full pressure still starts like crap Can Anyone tell me when to start and if anyone has the same problem and has diagnosed it please let me know what you have found. Its so aggravating


ANY IDEAS!??!?!!?

 

I have a 2001 Blazer that started pretty easy when cold, but after it warmed up it took a little cranking. We changed the starter, every sensor, fuel filter, etc. until we had the most exspensive part left to change and of course that's what it was, FUEL INJECTORS. At least that fixed our problem.

I think I posted this the wrong way earlier.

 

Yeah I think it might be the injectors but it's only got 95k miles on it
