Need some advice on elec on 250 xflow efi
Posted 01 July 2018 - 12:03 PM
1,ecu turns on with no error lights
2, surge pump and fuel pump turn on
3,I get good solid spark
1,no injector pulse so thought because the wires in bad shape could be reason why so i made new harness but now I have 12v coming from both wires out of each injector which I can't see why I followed instructions from microtech diagrams
2,tps was sitting on 58% when ignition on so I replaced that with new one now sits on 0% like as I read it should BUT now when u flatten it to the floor it goes to a max of 14% fuck i have been doing this car for last two months now and it is really getting to me if some one could help me with a bit of advice or even a point in the right direction would be greatly appreciated I will take a couple of photos of the ecu and that coz I don't no if that will help

Assuming you've fitted the TPS properly, you probably need to calibrate it now you've replaced it, So the ECU knows what is 5% and what is 100%
Some ECU's will Ground the injectors to turn them on, (Negative switched), If this is the case there should always be 12V when ign is on.
Sounds like you may need someone who is familiar with the ECU to have an actual look at it, May be a bit hard to troubleshoot over the internet.
