We have been working on this truck for about a week now replacing the intake manifold gasket. We took everything apart to replace it and now have everything back together and now it won't start. We have taken the distributor out and we couldn't get it to seat back in the right place. We have tried everything from moving the gears on the oil pump to make the distributor seat back in to the right position to bringing number 1 piston to the firing position. We have tried everything to get this truck started and have run out of options. Can anybody help please? As soon as possible would be greatly appreciated.

Another thing to add, the truck does roll over but it just doesn't fire up.

You have to have the distributor inthe right place or the cam sensor won't read right and allow the truck to fire. Bring #1 up to tdc with eh makr ion the harmonic balancer showing at pointer then point the rotor in the distributor to #1then hook up electrics and see if it will fire then. As you havne't given engine size the pics i'm sending are for a 4.3L. The mark on teh one distributor is where #1 should be on housing.

Thank you and we will try that tomorrow. If by any chance that doesn't work, do you have any other suggestions? And it is a 4.3 by the way.

Remove #1 spark plug. Tap the key use your finger to feel for compression on #1 cyl. Then turn the crank with tools until you feel the piston with a pencil. Turn the crank until the piston is all the way up. The timing marks will be close align the marks together. Now your on compression stroke on #1 cyl. Look at the cap the rotor should be pointing to #1 wire on cap if not remove and reinstall the the dist. With the rotor pointing to #1 cyl wire on the cap. Gl.

Well we got every thing fixed and now the heater does not work! Could it just be the heater core being plugged up or could it be something else?

Check to see if both hoses are hot when enginewarmed up if they are checkfor a vacuum line being off to the heater core, normlally through firewall. Then check tomake sure your actuators in heater are working. Generic pic enclosed.

Youll see the 2 heater hoses coming from the radiator and they go back to the heater core at the firewall. Their is a valve on the heater hoses. Vacuum operates the valve youll need to check that vacuum is going to the heater control valve.

@hmac300, I'm confused on what component each number is pointing to. @Cadieman, I will try this later, my girl is at work right now so I can't look at it yet. And if it's a bad heater core, how hard and how expensive is that to replace?

Also, @hmac300, how hard is it to locate the vacuum line for the heater core? And how can I find out if the actuators for the heater are working? Sorry, not very car literate.
