i've had the dancing problem with my iacv for sometime now(idle bounces around 1200-1700, up and down)
it's a 95 del sol s, d15b7
originally had no issue, did an auto-manual swap a few months ago and started getting the problem occasionally, completely went away by itself after a couple months
did a z6 mini-me a couple weeks ago and dancing problem came back even worse(flutters all the time at idle)
other than that, car ran fine til today
car was sitting at idle(no flutter), then danced up to 1700 once or twice then died
car cranks just fine, but won't start
let it cool down for a few minutes, started up, drove a couple blocks, then it died again.
did this a few times til it didn't want to start at all
need help, any ideas?

 

Possible coolant issues, I would check to make sure there is no air in the coolant system. Other then that just your normal vacuum lines. I want to say coolant tho since its only dieing and bouncing when the engine warms up.

 

car's been sitting and cooled down, still won't start though
bouncing problem happens whether it's warm or cold

 

Can you hear the fuel pump prime when you turn on the ign., it should run for a few sec. when key is turned to run, [not start]. 94

 

yeah even cracked loose the pressure regulator to check for gas. cylinders r gettn petrol

 

new iacv gasket, cleaned the f*ck outta the iacv, bled the coolant, checked all vac lines, no leaks. battery, alternator, starter all good
car cranks fine, fuel system is fine, one cel(torque converter lockup or whatever cuz ecu is for auto, irrelevant to starting problem), has brand new plugs n wires, dizzy is good
still absolutely no results
bump damnit, any ideas? haha

 

only other possible thought is something electrical related, but no clue as to what it could be
thoughts anyone?

 

bump

 

tried 3 new main relays, resoldered all of them, tried running on my old p06. no result
main relays only wants to function properly half the time, fuel pump will prime maybe half the time
no arc in spark plug wires
still no idea, need help baddd

 

Do you have spark?
Is there 12V at the injectors when ign. switch is in run and start?
Is there 12V at the distributor assembly when ign. switch is in run and start?

After trying to start the car, immediately remove the spark plugs, is there gas on them?

Make sure there is a good spark during cranking.

If you have gas, it's a no spark issue.
If you have spark, it's a no gas issue.
If you have gas and spark, it's a timing issue.
One of the above is "missing" or engine would run. 94

 

Have you checked the coil in the distributor? Just a thought.
