I think the first thing to do here is visually inspect the coil terminals for corrosion... It might be as simple as cleaning these up and voltage may be restored... test the coil itself next to be sure it ok... if so then I would run a new wire to the ignition switch... hope this helps...;-)

Do you need to change the wire or look better at the wire connectors? Removing or adding a wire in bypass is not the best.
How you figured out there is too much voltage drop? Switched all devices off before measuring? Did a resitance reading and compared that to the wire gage table indication?

I worked years on wire harnesses and testing them.

I replaced starter on 1989 f150 5.0 now have no spark

Mike, Check for diagnostic codes. Check fuses/relays,wires/plugs for pinched,damage or corrosion. Could be a lot of things like distributor armature, cap, rotor, stator, ICM, coil,spark plugs,wires, make sure ground is good to distributor. Use the attached forum links,instruction, guides to help diagnose ignition spark problems, Good luck

The large eyelet wires go to the large stud on the back of the starter. The one small eyelet wire goes to the S terminal on the starter solenoid

1996 cad seville no elec pwr try to start nothing. no lights etc.

The first thing I'd check is the battery. Sometimes a battery may enough volts to run some of the electronics, but not enough cold cranking amps to start the car. When this happens, a simple voltage check won't help. I have a friend whose battery on his F150 had 12.0 volts but only 450 CCA, so it had issues. After checking the battery at the terminals, check for loose connection at the wires. Then, I'd go to the fuse panels and relays. Once all of that checks out fine, then I'd investigate the ignition switch and ignition relays.
Of course, this is all on the assumption that you don't have an aftermarket alarm system. If you do, I'd start there. Many aftermarket alarms have a kill switch that disengages the battery or starter if the vehicle is being stolen. Good long as it works.
Good luck!

2002 pt cruiser. Just replace the battery a week ago and the cables, the car runs fine with the battery disconnected so it cant be the alternator. when you put the key in and turn it on without starting...

I had the same problem. Check the wire in the terminal on the starter. That terminal is not crimped well enough around the wire.
It is pretty hard to get to, but removing the air cleaner and battery helps. When the PT won't start, have someone get ready to turn the ignition switch to start, reach down the left side of the battery (facing it) And give those 2 red wires (about the size of a lead pencil) hard yank just after your helper turns to start. You'll pull them out of a snap in wire holder, (which you can put back later when it is repaired). This should put the wire to the starter in a bind thus letting it start. You may see some sparks as the contact is made, or if loose enough, pull the wire out of the terminal. If this happens, you found the problem. Hope this solves your problem.

I just replaced battery and alternator on my 1999 ford f150, still wont turn over, need advise

I'm assuming you mean it won't crank.I believe Fords still have an external stater relay,try shorting acroos the two large terminals with a screwdriver.If it cranks by doing this,verify you get 12 volts on the smaller wire when you turn the key to the start position.If you do,then its the relay.

This may not be a complete solution, but surely a place to start. Take the battery and get it tested. If it's fine, but the truck starts like the battery is dead... this is a great indicator that your starter is pulling WAY too much current. This could damage your battery, so replace the starter. Starters can also be removed and tested by your parts store before committing to a purchase. They are both easy enough to remove, you could take them both in and get lots of answers right away. If you have glowing wires, you should replace them as well as check all major wires from the battery to the starter, ground, starter relay, etc. before placing any new components in the system. Make sure your battery terminals are good and clean as well... this won't prevent shorts, but will be good maintenance while you're under the hood. Good luck!

Tell him to check and clean the battery terminals and the wires connections to the terminals themselves, the lights are coming on because they only draw very little power, the starter needs alot of power that it is not getting through the conncetions. Hope this help, let me know.

How can i check my coil pack on a 1998 f 150 4.2

measure resistence between companion outputs. they should be marked on the coill pack.12 ohm nominal. mesasure the resistence of the input terminal. 3 ohm nominal. i recently had a coil pack go bad on a '97 crown vic where the number 8/2 tower was reading good resistence when i kept the meter probe steady. if i moved it around while still making contact, it would change. i was getting a cyl. 8 misfire and found a bad wire and the plug was worn funny, so i changed the plugs and wires. this did not fix the underlying problem. the bad coil pack. the vehicle was misfiring at cruise but upon acceleration no misfire was apparent. what are the symptoms the truck is displaying
