Resolved 1G No Start - No Spark, No Fuel

[tsiawd90]

I need some help here I am stumped.

I bought a non running 1990 Eagle Talon, I have replaced the motor, fuel pump, clutch and turbo. I have everything that I can see hooked up.

The check engine light comes on for 5 seconds and goes off the boost guage goes up half way and stays.

I have swapped the ECU, I have checked the CAS position. I have checked my fuses. Nothing seems to change.

Looking for other things I should replace, check or inspect.

No start, no spark and no fuel from the injectors. I have fuel to the rail. I have a coolant light that is coming on.

Maybe I should check the CTS? Is there a way to bypass the sensor to see if that is the problem before replacing?

They?

Glad you got it sorted.

They is the mechanic that was putting in the motor. I think "they" connected the sensors together when they lowered the motor into the engine bay.

I have the car at my friends mechanic shop, they are working on the project as well. I don't have all the equipment or time to do everything that has been done to get this car running. I'll start a build thread later but this has been quite the project. There is a probably still quite a ways to go.

My plan was to get the car running and driving and then finish the project at my house. I had the car delivered straight over there after purchasing.

Sensors and harness ends should be male/female. Mistakes like this happen at a shop.

Agreed, this is one of the mistakes made in the design on the first year cars that they corrected in 91. I would have liked to sat in on some of the feedback sessions down in Normal during the early years.

They might of thought when designing it, no one would plug a sensor into another sensor and not the wiring harness. I guess they were wrong.

Speculating on how/why things happened can be an interesting spectator sport.

Some things are easy like in this case, they used existing sensors from other vehicles and that drove the harness design. You can see the change to the 91+ style parts across the product lines about same time so what was the driving factor is hard to tell if you weren't there at the time.

I've had some interesting discussions back when there were Factory MOD's in Normal but few people there had insight into the "why" meetings.
