Why won't my car start..?
Why won’t my car start..?
I have a ’99 Chevy Blazer with a 4.3 liter engine. I was driving down the street last Saturday night and the car stalled. I went to go start it, and it wouldn’t turn over. At first I thought it’d be the alternator because this has happened before with the same results. But the battery was fine, I even replaced it to make sure. I replaced the ignition module, and the coils and it still won’t start, it just cranks. I checked all of the fuses and everything is fine. The weird thing is my dad brought home one of those cheapy OBD II handheld scanner things, and it doesn’t work. I tried it on my Mom’s car and my Dad’s car and for both of them, as soon as i plug it in and turn the key, the scanner screen lights up. In my car it’s almost as if there’s no power going to that certain plug, but everything else seems to work, the windows, locks, radio, ect. Any help would be greatly appreciated as I am at a standstill here and do not want to go to a mechanic and pay a ridiculous amount for it.
Hey, thanks for the quick answers.
- Full tank of gas in the car.
- Fuel pump is fine.
- Fuel filter was replaced less than 2 months ago.
I’ll check out the ECM and/or the distributor…

Well, for one, it’s an American car…

try checking all wiring. Maybe something has been rubbing for some time now and it just happens that now it finally shorted out. How is your fuel pump and or filter??

Sounds like you need a new computer.

Sounds like the transflux capacitator. Have you checked that yet? Pretty easy to replace (and a cheap part). good luck.

Sounds like the ECM crapped out on it. But it could also be the distributor cap or the rotor button. But if it won’t communicate with a scanner I’d bet on the ECM. You can by a used one a the local junk yard or a reman. from a parts house.

First thing to check is turn your key on and look for a amber light that say check engine. Make sure that light come on and go out after about 3 to 15 sec with the key in on position. If you don’t have the light on the most likely your car computer do not get power recheck the fuses and fusible link.
If you have the light on then listen to the fuel pump running when you turn the car on, it should run for about 3 sec. and turn off. If you don’t hear the sound of the fuel pump then it would be your fuel pump or relay.

Since your Blazer is cranking, battery, alternator, starter solenoid are all out and are fine.
Since your car died while running this makes it sound like one of two things. Either plugged fuel line or problem with the fuel pump.
Best of luck

Because your OBD II scanner will not power up, it sounds like the ECM (computer) went bad.
