Hello everyone,
So I bought a 2001 Cobra with a blown motor and temporarily have put a 98 Mark Viii Motor in.
Everything is plugged up and she fires up as soon as you turn they key, then she shuts off immediately.
I PATS theft light cycles as it should, car shows mileage so computer appears to be talking I was able to plug OBD in and get a reading didn't get much for codes though as the car hasn't ran in months and computer hasn't been able to receive much to throw codes but it did communicate with the device. And for the split second she does start everything sounds healthy.
Has fuel pressure and injectors spray fine.
There is some issues vacuum wise but nothing that should cause the car to fall on it's face the way it does. Just some stuff that still needs to be buttoned up.
Unplugged MAF still didn't start. Unplugged and cleaned IAC still won't start. Has a new crankshaft position sensor. We're just kinda stumped and it's been a hell of a ride trying to get this swap done as it is which sucks because my last one was easy. The longtubes didn't help fitment though

Let me know what you guys think I should try I appreciate any help we can get at this point.

I broke my phone working on the car but I will try and post at least some picture.

Do you have an ODB2 scanner that is capable of monitoring operational data? If you did this might make short work of the problem.

Can you monitor the loop status? Want to know IF the operating mode goes from "OPEN LOOP" to "CLOSED LOOP" when the motor dies.

Here's some information on a very affordable Windows based unit.

While working on your car have you ever wanted: to find an ODB2 operational PID value (say fuel pressure or MAF)? How about graph a PID value over time? Or compare multiple PID's over time? Access a bi-directional PCM control such as test a...
