We changed the intake gasket and now the Jimmy won't fire,

It ran before we changed the gasket it was just over heating, we also put a new coil on it.

    I changed the intake gasket and in the process had to unhook everything on the top of engine including taking out the distributor and after putting everything back im not getting any spark. I replaced the coil but still nothing i know it has to be something i did in the process of unhooking and rehooking everything up. I just cant figure it out.I checked for spark by taking off the coil wire and putting a screwdriver in it on motor to look for spark but there is none.I know the distributor got turned while it was out of the jimmy but how do I go about setting it back in and setting the time the right way?

Get #1cylinder up to TDC (at timing marks on pulley) on compression stroke, and your distributor rotor should be pointing at the plug wire tab on cap for #1 .

I would have tried new pLugs and wires and using fuel injection cleaner in the regularly. You could also check to see that the Mass Airflow Sensor was not damaged.

1990 GMC jimmy 4.3 liter v6 is Being a ****

check to see if you have your plug wires at the right location on distributor cap. If you don't have a digram they are as follows- right side 1, 3, 5 front to rear. Left side is 2,4,6 front to rear. #1 should be on the location at front of cap closest to intake manifold. firing order is 1,2,3,4,5,6. Hope this helps. KS
