JaSSon Posted November 3, 2009 Report Share Posted November 3, 2009 Still screwing with this thing. Looks like now it's not getting spark. What typically fails in these? The coil pack? The Power transistor? The coil pack is wedged under the intake. I'm trying to build up the motivation to go out there and start ripping it apart.

Guest Removed Posted November 3, 2009 Report Share Posted November 3, 2009 (edited) check for crank and cam signals, also check fuses....if your getting all the ins and outs to the coils pack, then the coil pack is crap and also, there is a crank sensor...The crankshaft position and camshaft sensor are replaced as a complete unit.

JaSSon Posted November 3, 2009 Author Report Share Posted November 3, 2009 I pulled a cam shaft sensor out of an Elantra 4g63 @ pick-n-pull. The harness was different, but I spliced it together. Same condition. I double checked fuses last night, I can't find any that are blown. I'm using a Chilton's service manual. I just checked the ignition coil secondary resistance, they ohm out. I can't get my hands in to test the primary resistance without having another harness (junk yard maybe) or pulling the module. Anything else I should look at? Why did those assholes at Mitsu bury the damned coil under the intake and the fuel rail/injectors. I just need to get my hands on a COP assembly, slap it on and see if it fires up.

Guest Removed Posted November 3, 2009 Report Share Posted November 3, 2009 now if i rmemeber right, you was getting spark before when you was fucking with this thing...and i hate to say it, but the Elantra setup may have a different signal out put signature then the dsm one. cause the korean stuff is way different if i remember right. but it could be the same..might want to double check your wiring there just to be sure. i know swapping sensors like that in a honda cant be done with out other stuff getting swapped around...

John Bruh Posted November 3, 2009 Report Share Posted November 3, 2009 check your ecu and look at the caps inside it and see if their leaking. and check all other connections inside while your there. Quote Link to comment Share on other sites More sharing options...
JaSSon Posted November 3, 2009 Author Report Share Posted November 3, 2009 check your ecu and look at the caps inside it and see if their leaking. and check all other connections inside while your there. I've got 2 different ECUs. Both were rebuilt last winter. Quote Link to comment Share on other sites More sharing options...

I'll swap the stock CAS back in and double check. Edit: Installed stock CAS, reconnected coil, battery, etc... no spark! Fucking DSM! 2nd edit, tested spark from cylinders 3&4, neither sparked.

Lambguy Posted November 4, 2009 Report Share Posted November 4, 2009 Do you have the right test equipment to check the ignition output driver form the ecu? If so,check that. Then check the igniter output to the coils. P.S. If the ecu,crank or cam angle sensors aren't working in harmony you may not have pulse to the injectors either. Use a noid light to test the injector outputs. Could be as simply as a EFI main relay. And even if one of the angle sensors is bad it should still fire the coils. But the car will be in limp mode Quote Link to comment Share on other sites More sharing options...

Lambguy Posted November 4, 2009 Report Share Posted November 4, 2009 A lab/oscilliscope is the preferred tool to test wave forms and amplitude. But for a simple test of ecu and igniter outputs,a circuit tester like the Waekon SST will work fine as well. http://www.waekon.com/PS/sst42v/sst42vintro.html Quote Link to comment Share on other sites More sharing options...

(considering i watched a tech (gm certified no less) fry a pcm in a caddy with a tester just like that.) and just think about how the injector driver works. and then the issue of a noid light being used to test it. how many milli amps does it take to light the bulb off in the noid light? how many amps does it take to pull the needle up in a injector? big fucking difference there. granted getting a base idea if its working or not, it can clue you in, but i have seen this this back fire a few to many time's in my day. and watched people chase there tail on a pcm problem, because the noid light lite!

Lambguy Posted November 4, 2009 Report Share Posted November 4, 2009 A lab/oscilliscope is the preferred tool to test wave forms and amplitude. Rob,I understand what you are saying. And agree with you to a point. The idea here was to simply test for a output trigger. That's all. If that test probe is airbag safe,then it won't have an issue checking driver outputs on a 93 GSX. I have used one for years to do a "quick checks". Certainly wouldn't use it on CAN-bus or other systems extreme sensitive to current and/or voltage changes.

Guest Removed Posted November 4, 2009 Report Share Posted November 4, 2009 those "quick checks" , is where a miss diagnosis happens the most. and yes it can tell you , yeah, its putting out enough to light the bulb. but can it do work, like open a injector or fire a coil...due you under stand more of what im saying here? if you wanna lead someone down the right path to diagnosing a problem, dont put a fork in the road that can lead them right back to where they started.

Lambguy Posted November 5, 2009 Report Share Posted November 5, 2009 Rob,I understand exactly what you are saying. I'm not going to argue with you any longer. It's pointless. And I have better things to do. At this point we should be focused on the reason for this thread. Jason's lack of spark. So Jason,is their any update on finding the root of the problem?

JaSSon Posted December 12, 2009 Author Report Share Posted December 12, 2009 (edited) Got my hands on a new CAS. I now have spark! I have spark, I have compression, I have air (duh), I have fuel pressure... I have a running DSM! Mua-hahaha!

Drove it around the block...then down Main...then took it on 270 real quick! I forgot how loud it was tho! Quote Link to comment Share on other sites More sharing options...
