1995 chevy 1500 4.3. motor turns over but no start?

It might be your core pack. Try getting that checked at the auto store. Or it could be a gunked up fuel injector.

may want to have it checked out ,,,could be tappit,,valves and so on....could be so many things

Recheck your firing order for basics. If this is in good, a compression test may be necessary. Which enigine do you have?

Thanks for stopping by:

Right inline on the power line at the motor. Up under the dash.


I'll see if i can get you a diagram....

well you have to check for spark,compression, timing, and fuel. Spray starting fluid into intake,if it starts then a fuel problem exist.

code 12 is always present in gm motor products. it simply means no tach signal because engine is not running. i would go with the simple first and clean the throttle body real good . that takes care of 99% of idle problems.

You could have a dirty EGR valve, you can re move it from the manifold and clean it with Throttle body cleaner. Might as well buy two cans, since your cleaning the EGR, might as well clean out the throttle body too.
Spray the throttle body cleaner in to the throttle body with the engine running and try to keep it at 1000 rpm and then to 1500 rpm as you clean out the throttle body and let it idle down for 2 min then turn the engine off. Then turn the engine to the run position for 10 seconds and start and let idle, ro for a test drive and hope that solved the problem, if not there a few more things we can do which will consist for tune up.
Note: Clean the EGR first so you don't burn your self since the engine would still be cool before you clean the Throttle body.
Good luck and keep me posted.

1995 S-10 Chevy Blazer just replaced fuel pump now it is idles at 1500 RPM's what should I do.

Hello;
I would start with the fuse panel. Any blown fuses? Replace an dtry to start. On the firewall is a cover on the passenger side. Remove the cover and make sure the power is there. Check with a test light. The fuel pump relay is also there. Test is and also test the distributor and coil.
Hope this helps, rate me high please.
Thanks;

Have you check the injector relay or maybe a fuse for injectors.
