1996 gmc 1500 truck 4.3 L does not want to start when cold when it does start after many runs fine . has new rotor&cap & wires when warmed up it starts 1 st. time! it just started doin...

The ECT should be located near the thermostat housing, screwed into the intake manifold. There may be a couple of sensors in the general location so compare the plug in portion to confirm which one it is.

Before you change the sensor, I would use a scan tool to see what information the ECT is actually relaying to the computer. I know I've seen ECTs tell the 'puter the engine was opposite of the symptoms you're describing. In other words the ECT was 'saying' it was -40°. Yea you read that right, 40° BELOW ZERO! Needless to say the engine would run super rich with that info.

So I would say it's POSSIBLE the ECT could be 'saying' the engine is warmer than it actually is which would result in poor cold starts.

It may also be the Manifold Air Temperature Sensor (MAT).

The 'puter isn't smart and is only going to adjust the perimeters for air/fuel, timing, etc. on the info it receives.

I don't want to simply say "go buy an ECT and/or MAT and put it in" because I'm not a believer in loading up the 'parts cannon' and firing away at a problem. Diagnose then replace.

Hope this helps.

I have a 98 1500 that shakes on the uphill grade

first try running a high grade fuel injector cleaner in the truck, then pull out each spark plug and examine its condition if you find a black one replace the plug first if problem persists replace all plug wires and plugs the the distributor cap and rotor. Sometimes a MAF sensor can cause this problem

No Heat

You need to verify the blend door is operating and the heater core is not plugged or coolant flow to it is restricted.
