hey guys,
story goes like this, driving along and gave it a tad of a squirt in 2nd gear going up a hill, car misfired a little bit, i ignored it as i thought i must be running out of fuel as i was already low..
so i went and filled the old beast up, after taking about 10 seconds to turn over (usually instantly) i drove away, went to pull out on to the road and all of the sudden it wouldn't pull over 2500ish rpm, i thought that's very weird, as i was close to home i decided to nurse her home. max rpm became progressivly lower and lower till it got to the point where it was undriveable..
at first i suspected it was perhaps the fuel pump, so i had my eye on the knock light and monitering it like a hawk.. i have the alarm set at 30 counts per second and not once did it flash (power fc)..
from this point in the car would no longer start
after i got it home, i checked the fuel pump, all okay, checked fuel pressure, all okay.. i took the battery out and gave it a charge, and also pulled the seats out to do some other work, after i put it all back in i decided to try and turn her over for shits and giggles, and low and behold it started fine, i let it idle for about 5 minutes, then shut it off. about 20 minutes later i fired her over again, all good, gave it a rev in neutral to see if i could replicate any of the previouse symptoms but it reved fine. i tried starting the engine about an hour later and no go, would just turn over, so at this point i decided to check for spark (done with a timing light over the usual #1 plug wire at ignitor pack, it's a series 1) and no spark..
checked the 12V plug that connects to the coil side of the ignitor pack loom and it had 12V going too it, however when i performed a continuity test on the negative i could not get anything.. figuring that this must be the problem i then put in a temporary wire between that wire and the chassis to see if i could get her to turn over.. it obviously had current going through it as it sparked like all buggery when i connected it to the chassis, enough to make me double check to see i'd accidentally connected it to the 12V wire, which i hadn't.. i tried starting it but still no go..
i'm starting to think that perhaps the time without power gave whatever it was time to settle and come back good again, i can't see anything around the boot and rear seat area having any effect over the spark, so i think the seats in/out was just a coincidence, i'm thinking perhaps i have blown a ignitor pack, however i've got no pin diagrams and don't even know what the hell it does to be able to test it, unless of course it was just a loose earth somewhere, although everything else in the car works fine..
anyway, i would very much appreciate anybody's oppinion on the situation
many thanks in advance,
marcus
