my car wouldn't start today (corsa gsi with '90 c20xe from calibra)
had a quick look and there was no spark from the coil main lead.
had a fiddle about with a few of the electrical coonectors, but no luck.
called AA and the patrol guy was brialliant, did loads of checks and found no signal going into the coil amplifier, he even tried a new amp which he had spare in his van.
just wondering where the amp takes its feeds from. he looked at the hall sensor on the dizzy, and then the crank sensor.
hall sensor seems a little loose against the distributor body, but he checked under the sheath and the wiring itself is fine.
can't full access the crank sensor as it's behind the pas pump mount, but by shining a torch through the headers, he reckoned the insulation was not 100% just before the sensor plug.
i was just wondering if there was anything else that could cause the amplifier to not output a signal to the coil; or if it was one of the two things we looked at?
any input much appreciated.

could b the crank sensor..
can u get to the wiring connector for it which will b near your o/s wing i would think, lil three pin connector.
carry out an ohm test on pin 1 and 3 i think it is, and see what your getting.
check between all pins and ill look at the results if u post them up and compare to the data i have at home

Not another c20xe problem lol
As said above, fuel pump relay is a common one, there is a mod for it on mig web which cures the problem, soldeing in another resistor as it gets voltage surges or something.
The crankshaft sensor can cause alot of bother on these cars, at 56quid they dont come cheap but if you get a new 1, its ironed out one possible cause. This is what i did. Is your battery 110%charged?

the problem is no spark.
fuel is there ok.
AA man checked voltages at the connector by the o/s suspension turret, but i can't remember what it was showing.
my fuel relay is under the scuttle panel, and as i remember, there's only one there. i never realised ignition ran off a relay.
think my mums bought me the crank sensor today, so i'll try that, then come back.
cheers.
