ok i just replaced sparkplugs and wires and now it won't start i have checked all wires and sparkplugs nothing is wrong and the distributor it is all hooked up right according to the Chilton Manual i even made sure i had the right firing order was right and it was right so if you have any advice please let me know it is for the 2.8 ltr engine.

 

Logic dictates 2 things

1) You didnt hook a coil wire back in or knocked something loose.....check for spark.
Im pretty sure you are getting spark....

2) You didnt put the wires back on correctly. Find TDC on your #1 cylinder and start over. Its a very common mistake.

 

ok how can i tell which is my #1 cylinder

Excellent video, I only have one suggestion. Im assuming your engine is still in your car, so this is also a little trick to find TDC. Take the little red straw that comes on a WD40 bottle and fold a wide piece of tape over one end. (This prevents the straw from dropping all the way down the cylinder) Now insert the straw and start cranking the engine (BY HAND from the crank bolt) When she starts to rise, take it out and place your finger over the plug hole feeling for compression......hand turn the engine again and you should feel the pressure building up. You will know when you feel it. Now you have TDC, grab your #1 wire and run it to the cylinder. Go from there. One other thing to check....did you connect the distributor cap? I dont know about the 2.8, but the V8's have two small pigtails that plug in to the distributor....Ive made the mistake myself several times.
