I just put my 8v back in after the 16v blew up and the fuel pump is not priming off the key. When I bridge it with a wire then it runs, but won't prime or run off the ignition. I've double checked all the connections, the two red/black for the coil are on the -ve and the two black are on the +ve, the hall sender wires are ok, the wires to the pumps are clearly ok or they would run when the relay is bridged. Tried a diffrent relay, no luck. Any ideas anyone?
Could some one confirm this for me? I think its a faulty hall sender causing the problem as everything else is connected and not broken. Rubjonny, am I right?
hall sender would stop it sparking and pump running, but it wouldnt stop it priming. i think you have a wiring fault to ecu so its not powering up, 1st check is ecu relay. have a look in the scuttle as well there is a connector which goes between the ecu loom and car loom where all ecu power etc goes. is car pre or post 90?
I checked the wiring in the scuttle its all connected. Its pre90. I'll check the ecu relay when I get home. Which one is it? And which number?
Nope, id left it in there. I'll try a diffrent relay if it stops raining any time today, which i doubt it will.
have another look at the 2 2pin plugs in the scuttle as well, they arnt sealed so suffer from corrosuion. you could also check for ign live to the black/yellow wire while you're under there. have a look at ecu pins for corrosion as well, this is what made my 16v die one day without warning
oh when you swapped the loom back did you remember the 2 pin plug that fits into socket R? without that the ecu relay wont get power. and check fuse #17
Plugged it in and hey-presto! Fuel pump primes! And now to get that dizzy. Thank you Jonny, you've done it again!
try it again, the ecu wont have been getting power which is why both fuel pump wasnt priming and there was no spark
I got the other dizzy last night and have just put it in. Now what's happening is when I turn the ignition on I can hear a spark noise but when I turn the engine over there is nothing coming out of the kinglead. I checked the wires in the dizzy, they are all good, and then tried swapping the wires to the coil round (red/black on +ve and black on -ve) and now I get a very weak spark from the king lead and can still hear a spark noise when turning the ignition on. What is causing this to happen?
