No Spark....

peteremer · 09-09-2007, 01:15 PM

Ok so I just got a 1991 turbo supra last week for a really good deal because, it wouldnt start

. I tow it home and charge the battery and it starts, but wont idle worth crap and sounds really rough....

So I get a new battery, and check the alternator, look at the spark plugs <-- they were toasted and one of the wires wasnt plugged. So new plugs, and wow it sounded alot better but still wouldnt idle worth crap.

I start looking for vaccum leaks etc. and then while doing so re-sauderd the wires going into my cam sensor because they were like hanging all over the place and just looked bad. I find that the guy before me removed my EGR valve and didnt plug the vaccum lines! Yay fix. but I go to start the car....nothing happens. I pull out one of the wires, no spark.

Sigh...So I replaced my Coilpacks, Ignitor, and cleaned sanded down the edges of my cam sensor and still no luck. I checked the Continuity of every single wire in the "ignition system" from the ecu back, everyone was perfect. What else could it be?

I have someone sending me a new CPS because it looks like mine might have been one in a junkyard and could of had some moisture in it so we will see if that does anything..

Have any ideas? Thoughts? Please let me know! Thank yah all.

It was running. Then you did some work. Now not running. look closer at the area you were working on. CPS.

CPS, and make sure the harnesses to your coil packs are all hooked up, and then non the less check your engine bay relay box by the diagnostics for the ACC1 and ACC2 relays, i know if ACC1 is out the car wont start, it will just keep turning over.

Listen to mr nickleye. You soldered the CPS wires hint hint.

maybe when you were soldering it
u criss-crossed the wires

or maybe a few of the wires are touchinc each other

jus my 2cents

as per the idle problem, could it just be set to idle extreamly low?

I re-checked all the wires I saudered together back to the ecu and they all checked out alright...maybe my cps is just messed up. I have the new one coming tommorow, I'll let you all know how it turns out.
