okay well im ordering from rock auto. by any chance would you be able to tell me what they mean by rotor cam .526" and another is .475"...... thanks!

... I have no idea what they might mean. just get the proper year. 92-93, 94, or 95-97.

Figured out what it is. went n measured my disty. what they mean by rotor size is you know where the rotor pushes onto? yah that little triangle thing. some r bigger n some r smaller.

okay well got the brand new disty a couple days ago waited for the snow storm to stop and it still didnt fix the problem.. heres what ive done now..

All done with spark tester n multimeter.

replaced Crank angle Sensor - no spark
checked for spark out of cable - no spark
checked all wiring and fuses - good(that i can see) still no spark
tried a 2nd ecu - no spark
tried a 2nd module - no spark
tried a 3rd module - no spark
tried for spark straight from cap - no spark.
tried to see if there was spark from the coil - no spark UNTILL i LET OFF the key. yah LET OFF and it sparks for a sec.
test fuel pump - ON and circulating
test injectors n everything to do with fuel - tip top.
bought brand new disty+cap/rotor. no spark. also tried multiple modules too.

now what else is there i havent checked? is there a hidden fuse or relay somewhere or something ughhhhh!!!!!!!!!

Let off, as in back to the ON position, from START?

How's your battery?

cWs306 · Post by **cWs306** » November 21st, 2011, 11:23 am

its BRAND NEW. went and go it warrentied thinking that was the problem but nope

and yes let off as in i crank it and then let off the key as it goes to on it would shoot a quick spark.

Sounds like a signal issue. If you get that one spark, then the coil is getting charge, and then discharge... just no ignitor signal.

The ECM gets the signal from the ignitor unit, so its either wiring, ignitor, or ECM, assuming your fuel pump runs when in the crank position. If it doesn',t then its the sensors in the ignition module, which is the same part...

Using the correct T0T#'s disty?

Okay, go buy a cheap chinese $10 analog multimeter.

I suggest turning the rotor by hand to get the readings... so you can control the speed and you don't kill the battery. Need to go fast enough though, those hall effect sensors don't work if you go too slow.

HUMMMMM!!! ill have to check them then, and yes matched the tot number to the one that was on there first. and yah fuel pumps on and working, i tried jumping it in the little box on the fire wall with FP+ground and i could smell fuel like crazy. ECM? i tried 2 different ones. the k8 and the one i got in there now, the kl36. both the same out come. im gunna go re-wire everything again. solder plus shrink rap. eff these damn butt connectors.

Edit: and thank you again for all your patients and help with my car and myself haha.

The problem you are having sounds horribly much like mine!
Im still waiting for a new dirsty hoping it will fix it but reading your post and how similar your fault is im fearing that the dirsty wont work...

My car does the same "only i checked it with a LED to the ignitersignal in the serviceplug" Getting a ignitersignal only when the key goes back to the on position after trying to start

But i checked supplyvoltages in both start and on position and theyre both there and the main relay cant be the fault because it powers the fuelpumprelay and i can hear it running, ill let you know if i find out something.

cWs306 · Post by **cWs306** » November 23rd, 2011, 9:38 am

ahhhhhh

im thinking it might be the ignition thinger inside my steering column... idunno, im finishing the wiring today when the sun comes out, if i fire ill let you know! i found a couple shitty cracked wires on my harness by the 3 prong plug.. chopped and soldered new ones. just gunna splice into the new wires with the module wires and hope for the best.

Have you checked for 12v at all the places on the disty that should be getting 12v?

And does the pump work without the F/P ground thing? If you can spin the disty by hand and hear it come on, the sensors the the disty are likely fine.

To reiterate, it's seriously multimeter time. You're throwing money at it that you may not need to.

On a long shot though, check your grounds, more specifically I can remember the ground near the VRIS not be connected and causing me no spark.

Could you describe a bit more about that ground near the VRIS, where it is?
