Default 1995 chevy s-10 Blazer won't cold start

I have a 1995 s-10 blazer that will not start when it is cold out. During the summer, it starts up no problem. as soon as the cold weather hits, it won't start. If i leave it in my garage with the heater on, it will start up after a while without a problem and will run. If it sits too long in the cold afterwards, then it won't start yet again. I have put a new fuel filter, fuel pressure regulator, pickup coil, coil, plugs, plug wires, distributor cap, rotar button, and crank sensor on it. It is still having this problem. Any helpful advice would be appriciated!!!!

Have you tested your fuel pressure when the no-start condition occurs?

It needs to be >55psi for proper operation of the engine, but lets assume that your gauge reads low and move on.

Have you tried wiggling the wires that run to the fuel injection spider inside the manifold? They exit under the throttle body.

What brand of ignition components did you use?

Many people have chased problems only to find that the connector on the injector inside the plenum was loose & in need of replacement. Pulling the wires can allow the contacts to complete the circuit resulting in a working engine, even if temporary.

For something that is so easy to try, I'm not sure why you are being so hard headed about it... Regardless, I'll play your game this once, but then I'm out. When its cold out, wires constrict, plastic moves, etc.

Good luck with your problem.

sorry about that, i'll give it a try. And thank you

So I tried to wiggle the wires, but all it wanted to do is just crank over, like its been doing. Still won't start
