well to start off i looked for a lil while on here to see if anyone was having the same probs as me but i couldnt really find anything...

I have a 98 blazer LT 4x4 4.3 vortec with 4'' of lift and 33'' goodyear mud tires custom offroad and clearance lights and push bumper and lots of audio


so whats goin on is when im drivin or sitting at a red light it will start to die and will rev up to like 2000 rpm and then putter out and finaly die...
after this happens it has a hard time starting and now it wont start at all so im looking for some ideas on what it may be....

i replaced the fuel filter when this all started....the fuel pressure is around 55-60psi where it should be so it cant be the pump....im goin to replace the spark plugs and wires when i get a chance too...i cant see any vaccume hose this is broken or loose


im thinking it may be the fuel injectors just because last winter i had lots of probs starting it but when it did it ran fine after...had to use starting fluid sometimes too.....


if anybody has so ideas let me know plz....

 

How much does the fuel pressure drop in the first 10 minutes? Maybe leaking injectors or bad fuel pressure regulator.

if you do the plugs and wires might as well do the cap and rotor as well. But ceck the leakdown first.

 

yeah im goin to do tht too thanks forgot to say tht...


i never tested tht either ill have to go test it and let u know
thanks again
