without knowing exactly how you have done the wiring the only bits i can suggest is check earths on the inlet manifold are securely attached, check the crank sensor is connected and working, check you have 12v+ on the green with red tracer wire in the loom when ignition is on
Thank you for replying to my help plea aha, I have an adapter that was made for me. Consists of two relays and a set of fuses and the following wires....12v, ignition live, pump, speedo, rev, obd and eml connections.
Iwas told by somebody that as long as I had the ignition live (black cable on my loom), the 12v to the power on the 2 relays/fuses and the fuel pump wire connected it should start. Do i need the green/red trace wire from the orginal ecu connected to my adapter in order for it to work?
if your using nige's adapter there should be a battery+ connection, ignition + connection connected and fuel pump out all connected, in the original saab loom where your adapter plugs in there should be a large green & red wire this is the looms main supply for all engine sensors etc, no power here it wont run
Just had a look and it seems Im getting power to all of those wires. The direct ignition is getting power and the fuel pump which is turning on. Just no spark :/ - Reckon my crank sensor might be screwed? Theres 12v getting in, relays are clicking on with ignition and pump is turning on...cranks over using standard astra loom just no spark still :
is the loom powering up? the two relays are for fuel pump and the others for loom power the engine will spin over on astra loom and fuel pump will prime just from having the ecu connnected if the coil pack is not getting power then no spark otherwise its a crank sensor or knackered coil pack
is it one of my adapters or someones elses first thing to check is that you are getting a ignition live to pin 60, and that the ignition feed you are using stays at 12 volts during cranking a lot of vauxhall ignition feeds turn off under cranking
Hate to jump on someone else's thread but I've just brought a Saab 93 with a b204L in to put in my mk1 cavalier.
I'm looking for someone to modify my ecu and/or loom so I can delete the immobiliser and get a idea of what wires I need to to connect to make it work. If anyone has any info I would be extremely great full.
