Blazer dies.. While im driveing, my blazer will die when ever I speed up. Sometimes it will just be idleing and it will die. I had the battery checked and had to get a new battery, but it still seems to die on me. Can you help me out?

Take it to a repair shop

No one can guess at all the possible
problems it may have

Unless you work on your own vehicles &
provide test results & have a specific questions,
we can't do much for you

Have you checked fuel pressure under various conditions ?

Hi,

The possibilities are too numerous to get into here.

Either take your vehicle to AutoZone for a FREE diagnostic scan or they'll loan you a scanner. This will enable you to pinpoint the problem(s) almost immediately.

All the best,

Check the wiring connector on the coil. It may be loose. This really does sound like an issue in the ignition electricals similar to an issue I had with my 95 S-10. The coil itself had loosened as well as he wiring to it.

check fuel pump prasur

only half way there if you have a tbi check the crank sensor/ cam sensor that is the first line of business on that truck if the crankshaft sensor fails the truck stops dead when you wait a few minutes the sensor re energizes and the truck will work again for a bit antiknock can cause similer problems but not while the truck is running

Check the Fuel pump with a presure guage.

If your blazer is hard to start you can spray starting fluid in the throttle body and it is under the air horn. You remove the long screw which reveals the throttle body valve but do not press it open like a caruberator float just spray it in their. It helps if you turn the key on three times and then it should start. What does this all mean; Fuel Pump! I'm sorry but blazers are infamous for the fuel pump going out. Go to www.under100dollars.com and you can find a fuel pump for your blazer for like 70 dollars. If you get it from a auto parts store it's going to be like 200 or 300 dollars. It's not to hard to due but the fuel tank strap bolts can be difficult.

Just in Case you Doubt My Solution, It was Straight from the Chilton Repair Manual for your Truck.
