97 hond accord 4 cylnd special edition replaced ignition switch and starter and still will not crank or have power to starter if I put power to starter I can start it and it will stay running but u still can't start it after with the key Nor do the power widows or door locks work no power

Hit the starter while he has the key in the start position. If it cranks replace the starter.

If the truck cranks over you have voltage at the ignition switch ! From starter to switch , First off starter to what switch ,ignition ? There is a 175amp fuse that supply's battery voltage to the power distribution center - fuse box under the hood . On the lower right side of the radiator support, below the battery !

Only way to be sure the pressure is ok is to remove the switch and connect a pressure gauge, should be above 10psi at idle , if ok replace oil pressure switch. If not the oil pump strainer may be blocked or the relief valve stuck or spring broken.

Problem with 1998 Honda Accord 2010 ford edge starts intermittently. Replaced no crank is
1: a weak battery (try different good one, or jumper cable it)
2: bad cables or conn. from battery to starter.
3: bad starter.
4: bad key line (alarm cut, PRNDL switch open, bad ignition switch.
Five minutes with any voltmeter finds this easy.
or or hot wire the starter solenoid, to cut the problem in 1/2
this proves problem is in starter or battery
or in Key line, in 5 min flat, (a 100 year old test )

there are very simple tests for each of the 4. ask.

About the only thing you didn't mention was the starter itself. You could have it tested. But before that, try to see if you have power on the small wire to starter solenoid on the starter, when key is held in cranking position. Pull the small wire off and check for power with a multimeter or a testlight while someone holds the key in crank. This is the signal wire from ignition switch that closes the elec. contacts inside solenoid so the starter gets full power from the battery to spin. (This wire also is in the circuit with the clutch switch and the starter relay.) If you have power on this wire in crank, it is very likely the starter is bad. If there is no power, check that circuit out. It is losing power somewhere from switch to starter solenoid. Good luck.

Starter relay is bad.

will your car start if you put ignition key in run postion and then put remote power to the starter to crank engine? If it will you probably have an issue with the electrical portion of your ignition switch. Check to see if you have power to the high voltage side of your starter relays. If not check for a bad fuse. If so check to see if low side powers up when key is turned. If so it means you are gettintg current from the switch. So keep checking for power all the way to the starter. If not check and replace the ignition switch.

There is still the starter relay and the actual ignition switch to check. Either could've failed, preventing current from going to the starter while trying to crank the engine. Check them out.

It could be the starter, test the small wire going to the starter, it should have power when turning the key to start/crank. If it does, and the starter will not crank the engine, whack it with a hammer, if it then starts, replace the starter. If there is no power to the starter, then it could be the ignition switch, or the neutral switch, or a fuse/link blown.

check powers out of the ignition switch big in big out usually first place to start
