    Ok so just I got my 302 rebuilt in my maverick it's bored over .60,edelbrok heads,intake,cam,carb,and hooker header,k so I was trying to get it started but it turned over slow but I'd get back fire so I knew I was getting fire,so I thought it was the starter that I needed a high torque starter but then I bought a new solenoid for it and cranked up great!! Only problem was..I'm not getting any fire now:( idk what happened please help!!!!

    You say it cranked up great yet it's not getting any fire? Do you mean it turned over great but did not start up?

    Was it an exact match solenoid? Also, some solenoids are grounded at the base, while others are not, make sure the ground is secure and make sure your grounds are in a loop Frame-Body-Engine-Frame...I had this problem with mine and it was a ground issue...it would turn over repeatedly but never fire...I replaced all the ground wires and added a few more and it fired right up.

    If your Solenoid is mounted on the engine bay make sure its securely connected and has a good ground, you may want to run a wire from the base of the solenoid to the frame or engine(Of course this produces another wire, but you can just use it as a temp test-wire until you figure out if thats the problem)

    Idk if it was the exact match the guy just grabbed one from the back and gave it to me lol,and the only wire I replaced was the wire to the solenoid to the battery I'll try buying one for the ground wire too and see what happens after that,and yeah it's next to the fender so it's on the car I'll see what happens tomorrow gotta go to work:/ haha

    i would check for spark. take the coil wire off the distrubtor cap. hold or set on the motor so there is about 1/4" gap between the terminal and the motor. have some one crank the motor over for juse a few seconds. you should see the sparks jumping the gap. thats really the only way to be sure if you have spark. i suspect that you do and your problem is the distrubtor is not in the right location.

    K so I bought another coil and I got spark now but it's really weak spark so my guess now Is the distributer not getting enough spark to the plugs so I guess it's down to that now hopefully it works

    the distrubtor has nothing to do with the strength of the spark. its all about the voltage that gets to the coil. you need a volt meter and need to measure the voltage on the possitive post of the coil when the key is on. also your battery needs to have a good charge to it.

    Well the distributer is nigged rigged lol we took off some parts from a 460 distributer and the wires from it too that's why I'm thinking it's that,and the batt is fully charged too

    ummm ****** rigged is highly offencive. i perfer to offend a mouse not fellow humans.

    well you know what your distrubor is but if its causing spark to fire while cranking and the cap and rotor match it should be able get the motor started. you need to check the voltage that the coil is geting.

    no its not the coil. its the power to the coil. dont buy another coil, buy a multimeter. use it to test to find the problem. you want to put the black leed on the neg post on the bat and the red leed on the postive post of the coil. now turn on the key. you should have 6 to 9 volts there. if you dont then you need to follow the postive wire back to the connector at the back fire wall. disconnect it and put the red leed on the wire that is in the plug that comes out of the fire wall. your trying to find where the resistance is that is causing the coil not to get the proper voltage. try that and post what you find.
