I’ve just completed my GTE swap install and I get crank but no start. I have fuel in the return side.

My concern is the ECU. It has the immobilizer in it but I don’t have a plug on my harness. I had a key programmed for it. Is this a reason for no start?

also, what is this plug for on the body harness side?

 

I assume you’ve gotten it running by now but if not, maybe this will help? The immobalizer ecu kills the fuel pump and will not allow your car to run. I had this issue when bypassing the abs. Source a non immobalizer ecu if you can. Next thing would be to see if you used the jumpers from the aristo( Orange and black I believe). Lastly, I had issues with a bad fuel pump. A walbro 255 is a great replacement.

 

I got it fixed. Ended up being a blown intercooler pipe.

 

How did you overcome the immobilizer ?

 

Sorry. I had a lot happen that I didn’t explain. I got a non immobilized ecu after talking with the guy that did my key programming. I didn’t want to go through the hassle of making that setup work. Then I got it running and it died. Because I blew an intercooler hose.

 

Glad to hear you got it running. The immobalizer ecu are a pain. Makes things difficult.
