I'm trying to get my engine started again and I don't think I'm getting strong spark. I'm running a Haltech E6K, which says I'm dropping to 8.3v during the crank. I pulled a plug and confirmed spark by laying it on top of the intake manifold, but the spark looked really dim. My timing light won't pick up a signal. Can someone confirm whether or not the coil packs are getting enough power so I can move onto the next troubleshoot?

8.3 is kinda low. hows your battery, did you try charging it.sigpic

Average voltage drop during crank is in that range. If you are getting spark the coil is working under low drop out voltage. Next is fuel?? and Air?? Have those aspects been troubleshooted?I am back

I've got fuel pressure and the Haltech is telling me its firing the injectors for 1.18ms. Considering I have 550 injectors (three batches of two injectors each), I think the motor is getting too much fuel. Is it possible?Comment

too much fuel. try leaning it out to fire. and disconnect your injectors and crank the engine to try and get some of the fuel off the plugs. you may have fuel fouled them. step up to a heat range warmer (unless ur turbo).
think about changing that oil, ive had a disasture with fuel dilluted oil..no bueno3500, 1280 cam and PR, ls6 valve springs, port and polished heads, ported lim, ported uim, 4.3 70mm tb, ported trueleo headers and y pipe ALL FOR SALE (minus the car)

Does yours have a Flood Clear mode? I know on mine (Megasquirt) it will do it if you go past 80% throttle and under 400rpm. Sometimes after the first couple of tries if it doesn't start up it'll flood, so I just give it WOT and it starts.Originally posted by evilmiata View Post97 Cavalier RS

I don't think the E6K has a Flood Clear mode. My RX8 does, so I tried it on the 3.4l through habit without success. After getting the Haltech to feed .624ms of fuel, I went to pull a spark plug and see if it was wet. Well, the spark plug wasn't but the fuel rail is soaked; the schreader valve doesn't appear to be holding pressure, so now I need to figure out a work around.Comment
