Hi , i have still a couple problems with my bird,
i have build in new parts
fuel relay
fuel pump
fuel filter
spark plugs
rotor
disputer cap
icm
oil
oil filter
steering pump
steering cooler
coil
air filter
new brakes
now THE problem
i am getting fuel and good pressur ,relay,s are working ,fan is working ,ses is on with starting,pump primes 2sec with key on and after starting the oilsensor is working (fuel pump runs) after cranking THE pump runs 2sec after key in off
but i have no spark engine is turning good injectors are clicking
so what can it be

 

Hi ,i have try start iT ,i have power to THE coil 3wire not THE white
i try THE old coil and Icm still no spark

the fuel pump prims and after oil pressure THE pump is pumping ,and when key is of a sec2/3 still runs
cooling fan runs

so what can iT be

 

Check continuity in the coil to distributor wire. I had a bad one once and spent days trying to figure out why my car wouldn't start.

 

Thank you 👍I will take a look at that Tomorrow

 

Hi ,i have power to THE coil to THE Icm , i have try to take THE mas off and THE connector from Icm 4pin
and still no spark

 

Hi what are THE symptoms of a broken pick-up coil

 

Some random thoughts here;

If your injectors ARE truly being pulsed while your cranking the engine, then your pickup coil should be OK, your ECM will not pulse the injectors unless it gets a signal from the pickup coil (through the ICM) indicating the engine is turning. If your really curious, unplug the coil from the ICM and put an ohm meter across the two terminals. It should read some number of ohms that you can find by doing a search, it should not read "open" (Infinity) nor "shorted" (0 ohms) . Next measure from each terminal to ground, this should be infinite ohms (open circuit, no connection).

Have you verified that you do in fact have +12V on the fat pink wire on the coil while the engine is cranking?

I have seen an ICM fail in such a way that although it will supply the ECM with the cranking signal, it will not fire the ignition coil.

I have seen plenty of ignition coils that will pass an ohmmeter test, that flat out won't make spark in the car (The usual failure being internal arcing that only happens at the high voltage the coil operates at, and is not detectable at the very low voltage an ohmmeter uses to take it's readings).

Hopefully that'll give ya some direction toward troubleshooting it.........

 

Hi 👍 Thanks ,when i am home Tomorrow i Will take a look at that 😉

 

Hi,i have 1 ohm on de lead from THE pick up ,and that dont chance when i conect THE 2 leads of THE multimeter
,iT dont read between 500/1500 ohm ,i think THE pick is broken i have orderd 1 today
hope iT THE car starts 😉

 

Hi ,iT starts and runs ,but when i give iT Some pedal to THE metal ,iT bogs en stutter,
the magnet is cracked and little pieces off ,can this cause that THE motor not run good

 

Hi i cant find this part dont know how its called

if you need a distributor I have stock and a few aftermarket. I think this is what you need might double check application.

 

Hey, Tuned performance,

Do you have V6 Distributors? That link looked like a V8 shaft, or are they the same?

 

Opps sorry, just have tpi, tbi v8 distributors

 

The AC Delco rebuilt distributor from RockAuto is listed for $120. I don't know the quality of these distributors, but it might be worth buying, even if it's just used for parts.

 

Yes the magnet being cracked will cause all kinds of bad running, and, no, if it were my choice I'd stay away from the rebuilt ones and go for one of the new ones . "AC Delco" is just a name used to rake in extra $$$$ from brand loyal people, the stuff is all made in the same offshore factories anyway.....

 

Hi👍👍 i will go for a new one ,Thanks for all THE info and help 👍👍👍😉😉
