no spark

Postby Bean » 10 Nov 2007, 19:27

i've spent the day on the Chevette today. Got the fuel to flow (after spending about 2 hours unblocking the feed from the tank), new cambelt on and bled the clutch.Tried to start it but i have not got a spark. from what i found out before it went dark there was no power going to the coil.
My question is, can i just put a new poss + negative supply to it or does it need a certain supply?
Also if i put a new feed to it what size fuse should i put to it?

Test the ignition feed with a test light (filament preferable). As you car has been stood for a while there could be corrosion in the system or maybe the coil has expired, thats why you need to test it with a test light. Give it a whirl. :idea:

i connected the poss and neg wires off the coil to a bulb to see if there was any power there but there was none. Checked all the fuses and they were all fine.

Check for power at the fuse... And Fusable Links (if any present).

Damaged or broken wires along the harness? Faulty ignition switch? Loose harnes connector ( at firewall, ignition switch, et cetera)?

Check the connector at the bottom of the steering column that links the ignition switch to the rest of the loom. My car refused to turn the engine intermittently, tried everything including the 'big hammer on the starter solenoid' method, but eventually traced the fault to a dodgy connection between ignition switch and starter solenoid. However, if all the lights etc on the dash are coming on, then perhaps the fault is with a broken wire or blown fuse. Best thing to do is to trace the loom back from coil +ve to source.

Could also be an earth problem - have you tried checking between the +ve and the chassis?
