i have replace the starter, which tested bad, i replace the main 175amp fuse block, tested all the other fuses and relays, the alternator is good, i have new distributor cap and rotor, the iginition coil is only 2 years old, i replaced the battery cables and the batter is fully charged, i replaced the fuel filter, i replaced the throttle position sensor and idle module, i also have replaced the plugs and wires
when i turn the key the fuel pump and lights come on but nothing else happens, i took the wire going from the coil to the distributor off and no spark came through it. help me please


ok i got your message thank you for answering and i will make a donation as soon as my truck is fixed and my wedding day is over.

i have no spark going to the ignition module, which i replaced, and no spark to the coil. the starter tests good. the only thing that happens when i turn the key is the fuel pump comes on. my ecu is throwing code PO413, something about an secondary air control. other than that it ran fine before i would not start. the oil looks good. the engine can be turned with a wrench so the engine isnt blow. the plugs are brand new acdelco platium, the distributor cap is new from napa and rotor. i am stumped.

I assume that when you took the coil wire off the engine was cranking over right?
If so, you must check for spark at the plug first. Obtain a cheap sparkplug tester that you hook up right inline with, or directly to, the spark plug wire at the plug. If no spark test the coil. If still no spark test the ignition module.(most it's the ignition module) If still no spark check all the wires leading to the ignition module. If all tests out good let me know, we'll move on from there..The key is to test all the items you suspect first and don't just go changing things. Autozone will do these tests for free...What brand of plugs,wires,cap-n-rotor did you use?
