1989 Chevy Blazer won't start.?

Question

Just got my 1989 Blazer used from an old family member, who never had it registered and sold it to me. I drove it 1 day after battery died from blistery cold weather, charged it up, and it started right up, drove it all day ran fine...wen't to bring a friend home, and it won't start up, it cranks over fine, but not getting gas into carborator, why? any help...

Answer 1

This little trucklet doesn't have a carburetor, it has fuel injection, and you can't see fuel anywhere around it unless it is running.
There isn't much you can do to tell if there is fuel present unless you have a fuel pressure gauge and the wherewithal to use it in the fuel system.
The fuel pump is located in the fuel tank.
Ask a friend to sit in the driver's seat, and turn the key to ON (don't try to start it) while you listen very closely to the fuel tank at the fuel filler with the cap off.
For about the first 2 seconds after the key is turned on, there should be a "HUM" from the tank, then the computer will turn the pump back off. If you don't hear it, turn the key off for 15 seconds and try it again.
If you can hear it, chances are that there is fuel at the injectors as long as there is sufficient fuel in the tank (don't trust the gauge, if it is low, add a couple of gallons).
Remove the coil wire from the distributor and place it near a bracket or bolt on the engine and crank it
Is there a strong blue spark? If so, move on to on-board diagnostics. If not, repair the cause of no ignition spark (defective coil, failed ignition module inside distributor).

…and scroll down below the chart for an illustrated discussion of the procedure for retrieving diagnostic trouble codes from the computer. It is simple and only requires a paperclip.
if there is a computer related cause of a no-start, there will be trouble codes stored in the computer unless you have disconnected the battery since the cause of the no-start. With the codes in hand, refer to the chart to identify which circuit or system you need to address for proper diagnostics and repair.

Answer 2

check gas filters, in line and the one in carb, probably full of crud.

Answer 3

first be sure you have enough fuel, then check, fuel filter,fuel pump pressure,carburetor float setting,s................did you say 1989............that should be throttle body injection.
