Finally my engines in and all plugged in, turns over fine but getting no spark and no fuelling.

Checked the relays were the right way round n thats fine, all the plugs are in. The only bit of bdged wiring is at the inline fuel pump where i didnt have a plug so i wired the terminals in with connectors but the inline fuel pump isnt the one which primes anyways so dont think its that.. Checked all the earths and there all connected up.

anyone got any ideas?

Mine didn't start one time after sitting for a bit. Turns out the hall sender had died.

Is the yellow fuse the single one on its own?

hayesey

yeah the only blade fuse on the car, on the top of the fuse box with all the bullet fuses in.  The 12v supply to the injectors and fuel pumps goes through that, you should still get a spark though even if that had blown but it's easy to check!

Got a brand new dizzy so surely can't be the hall sender hmmm

PeteG40

position of the dizzy? mechanical timing? shit ground?

Etches

Two connectors by the coil pack? What are these? I have one into the coil pack and the others are just the thermo switch and the fan plug. Yellow fuse isn't blown tho

hayesey

theres a 3 pin plug that goes into the coil and a three pin plug/socket that connect together next to the coil, usually on a metal bracket bolted on with the coil.

Got them the right way round as the wire colours match, if the yellow fuse hasn't blown does that mean that I hav the online fuel pump connectors on te right way?

Etches

Someones said this aswell to try

if you're not getting sparks or the fuel pumps priming, Id check the wiring to make sure the ecu is working. can you hear the relays click when the ignition is turned on? if not make sure you have a live ignition feed from the plug by the coil. the black wire should be at +12v when the ignition is on. also when the ignition is switched on and the ecu is working, the wires to the injectors should be at about +10v (from memory), as its a negative pulse that fires the injectors.

if you can get a spark, then the ecu should be working. if you cant borrow a spare ecu I've heard of people using one from a GT to see if the ignition will work.

also on a GT the fuel pumps will still prime even if a distributor isnt connected

had same problem my self check you have got the white plug on the throttle body is the correct way round!
