95 blazer will not start HELP PLEASE

[travtug123]

Hi I am back. The truck is not starting. But I should tell you a few other details. One day on my way home I was on the interstate going about 70 mph truck started bucking and stalling out. Pulled over the truck dies. It restarts and I made it home going about 30 after truck would get to two grand and starts misfires what you want to call it. It is a 4.3L Vortec. The fuel pressure is staying right at 60psi even when it was misfireing. We found that the 1 injector had a leak. And the intake gasket also needed replace. So we replace the injector put it all back together. Truck started right up ran real good drove it up and down the road ran real good pull it back in the garage change the oil. Restarted the truck was sitting there run then dies will not restart. I really am begin to wonder why I got this truck I should have no better.

it could either be the fuel filter or your fuel pump going and not getting enough gas to the injectors do you have the spider injectors and did you change the whole thing

When it quits check for lose of fuel pressure or lose of spark to all plugs.
Check all wiring and plugins?
What engine code and does it have flat top dist or old style?
Computer on fender or behind glove box?
Any codes or check engine lights?

Look more into your fuel pump 60 psi is minimum pressure for this truck. The next time your truck dies and won't start check for a good blue spark. If you do then most likely your fuel pump is dieing. Also check the plugs going to the fuel pump and also the ground strap. Mine would sometimes die and not want to start and the pressure would read 60 but a few minutes later would start, I replaced the pump and now I have 62 psi and haven't had a problem since. If they got spark and fuel they have to run right= not always lol
