ok i replaced the starter and the ignition switch iam confused when i turn the key sometimes it cranks and starts no problem and sometimes when i turn the key nothing happens. the dash lights are on when the key is on the ON position, so idk help please

oh and it does start if i jump the starter

did you have the same problem before changing the parts? did you replace the whole switch-(key cylinder & igntion switch)- , or just the key cyl.? if whole thing was done, then check your grounds. how's your battery? test, don't guess.

yes i was having the same problem and my battery is brand new i changed only the ignition switch i dont think its the key cylinder because before i put the new switch in i pluged it up and used a flat head and turned it nothing....

check the neutral safety switch for adjustment & wear. since you've changed engines, re-recheck grounds. add ground from starter mount bolt to chassis...atleast 4-6 gauge wire. recheck all harness connections that may have been moved, damaged or not reconnected tightly.

It's probably grounds or bad connections. Check both connections on the starter, and don't forget about those two big ones sitting on that acid filled plastic box.

well its a 5speed and as far as i remember the only ground i have is the negative on the battery cable ill go add that ground you said

iam sorry but i have no clue what box your talking bout

that would be the battery bubba

for 5sp, there is switch that is activated when the clutch pedal is depressed. sort of a neutral switch for 5sp. be sure it's good and is being fully depressed when starting.

i had the same problem it was my ground the bolt was broken. check your grounds

The grounding strap bolt is located in front of the slave cylinder. I'd check that first. It should connect under the battery tray.

thats connected

Try running a new 4 guage wire from the + terminal on the battery to the + starter terminal. It sounds like the wire to the starter may be corroded.

to ground issues and adding the tranny/starter to chassis ground. Don't count out the possibility that you got a bad starter either, but definately add the ground first.

When you say jump the starter are you talking about taking a screwdriver and jumping the turn-on and constant leads? If so, then your problem is strictly related to the turn-on signal, which would most likely be the ignition or clutch switch. If its neither of those I would DL the factory service manual and start with other switches in the circuit, then move to relays.

You need to make sure you have power to the trigger wire. have someone try to start it and put a test light/multimeter on the trigger wire that runs to the starter solonoid, if there is no power there then you have an issue somewhere else and can start checking further into the system.
Assuming that the starter/IGN switch is the problem causes you to miss a lot of diagnostics in between those points.
Check the trigger wire for power then post back.

Check the clutch pedal switch.

Also make sure you check your fuses, there's a 7.5 amp fuse labeled "start sig" it is somehow related to the problem. My car had the same exact problem, it was very frustrating! I decided to install a push-button switch to start the car, wired directly to the starter, never felt comfortable using it but i had to start the car somehow! Then I changed the clutch safety switch, nothing. I jumped the wires on the clutch interlock relay, nothing again! Finally I changed the ignition switch, still nothing! That's when i looked at my fuse panel, and found the "start sig" fuse blown, replaced that and the car now starts every time! Yay! I think in my case though, I think I blew the fuse while i was using the push-button switch, or using the screwdriver to jump the starter terminals... My old ignition switch felt kinda "jiggly", the new one feels a lot better, which makes me think that might have been my problem all along

if its manual u have to make sure its pushed to the floor if its an automatic ur nuetral safety switch might be taking a dump

Being connected doesn't matter. Amps vs Volts. Volts can flow through the tiniest and poorest of connections, Amps will not. Google voltage drop test to learn how to find the part of the circuit that isn't allowing high amperage to pass through. After checking clutch switch of course.
