1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic

i have a 95 blazer with the 4.3 in it. Last sunday I drove it and monday it would not start, it will crank fine but thats it. I can hear the fuel pump prime and I did check the coil for spark and it does. I havent had a chance to go any farther yet due to the weather. (Do you have any ideas where I should look next?)

If you have the spider fuel system, I'd start by checking fuel pressure.

Can you check for codes?

I can barrow the tool to check the codes. I had them checked just before it quit due to rough running and backfire and it said missfire cyl #6. The codes were reset and the service light came back on when I drove it again. Im thinking maybe plugs, wires and cap but not sure. Will low fuel pressure give a code?

Hello, sorry I didn't post back sooner. If you have the cmfi, it might be a sticking poppet valve for the fuel system, have you tried injector cleaner?

Just about anything can cause a misfire, fuel--spark--compression. I'd check fuel and spark at the number 6 cylinder.

Well I think my starter is fried now. I hooked jumper cables up the other day and it started cranking without the key and now the cylinoid wont even click on anything.

It may just be the solenoid? The solenoid is what connects battery voltage to starter field terminal. As long as the starter terminals aren't accidently shorted to each other?

Hello, if nothing electrical works, make sure the battery has a full charge. The cables/wires all clean and tight on both ends.

There is crank feed to the starter solenoid, purple wire, goes hot with the key in the crank position, then the solenoid connects battery feed to the starter field. There is a terminal from the lower part of solenoid into the starter body, that is the field terminal. With the key in the crank position, that circuit should be hot?

Any testing you do, make sure the tranny is in park or neutral.
