b18b1, long story short... ctr pistons.. stock ls cams... crower dual valvesprings... (had other crower cams of course, sold em)

every once in a while, ill have to pump the clutch to get the motor to start, any idea what could cause this ?

 

either the clutch switch that prevents you from starting in gear is bad, or the act of pumping the pedal is shaking a faulty relay into working.

good luck, either way its only a matter of time before the pumping stops doing the job.

 

so how would one trouble shoot this problem. How easy is it to check the clutch switch or switch it out with a new one and also if it is a relay problem... does that mean.. its in the wiring ?

 

First..... back up to the beginning. When it "doesn't start", is the starter cranking over the engine but it won't fire up? Or is the starter not working?

Unplug it & use a multi-meter to check continuity thru the switch as you press it's button.

If that doesn't get you anywhere, then you need a wiring drawing to check the rest of that circuit.

Also check to see if the clutch pedal is pushing in the button when pushed down all the way.

actually, the motor wont even turn... it does the "click" thing.. all you hear is click, and you go to turn the key again.... click...

i know this might sound like a red flag but i fegured i would post a topic on it anyway, find more out...anyway.. when doing the motor swap i did.. the wiring harness didnt work for whatever reason, so i basically had a buddy take 2 wiring harness's and make me 1 good one. And its been working out fine and then all of the sudden it started doing the "click" "click"... the starter doesnt do anything, obviously the motor doesnt either.. just curious, thanks for all your help though!

i suppose i should just wing it , or probably buy another engine harness.. then again, i dont even know if thats the problem or even if the engine harness relates to this problem whatsoever?

 

Since that harness used to work, you can check it's connections rather than scrapping it.

Is that clicking sound coming from the starter? Or is it just something like the main relay under the dash?

When you try starting, check to see whether the small signal wire at the starter is getting battery voltage. For that matter, measure whether the battery voltage drops much as you turn the key to 'Start'.

Clicking sounds like the starter isn't getting power. Remember the starter needs far more power than everything else put together, so please check whether the battery itself is weak.

Dirty/corroded/loose connections at battery?

Dirty/corroded/loose connections at the OTHER end of each battery cable?

Did your buddy do any splicing in the high-current circuit for the starter? Check that for loose/corroded/etc.

Try again & hit the starter with a broomstick. Maybe the starter solenoid contacts are getting dirty or burned up?

 

You should check all the things mention above. But I would first recoment that You check the small pecie of ruber that physically pushes the button For you cluch. That has gone bad on a couple ff my cars an it is to fix.

It is always good to check for the easyes cheapest thing to fix first. Could be the battery to but I think it is some thing to do with that cluct switch.

Another way to test it to just hold the button down and try to crank it. Make sure the car is in netraul.

 

Thinking about it, you need to check whether the little signal wire at the starter gets battery voltage when you turn the key to 'start'. If it does, then your clutch interlock system (switch, relay, & wiring) is ALL OK.

In that case, you can concentrate looking at the starter & it's high-current circuit. Namely, the starter solenoid & the big battery cables.

 

wow, you guys are dope first of all, you know your stuff

i do have a very high cr, in an ls... with a standard battery.. the battery does not have a lot of cold cranking amps... that takes effect on the starter having enough "umph" right?
