    Engine Cranks no Start

    Here's where I am at. I will have the leads for my multi meter today so I can back probe the crank sensor. Aside from that, I have gone through the "No Start Tree" from Vortexbuicks. I end up at the end of step 3 "Spark on all" > Check for fuel wet spark plugs. If OK see "Diagnostic Aids" on...

    Thank you. I have all of the wiring diagrams.

    Yes I have checked the crank sensor. The air gap is .025 between the sensor and the reluctor ring. I am not sure how to test the sensor itself.

    Engine Cranks no Start

    Sorry I posted that accidentally. How would I identify the ground strap for the coil pack? If that is one of the wires under the coil pack, it is fine and connected. As for the fuses, there are three associated with the ECM and drivetrain. Those three fuses are there and good. There is no code...

    Engine Cranks no Start

    Ok so now for some specific questions: Since this is a custom built car things are a bit different. It does have all of the ECM and sensors. Only things required. It's been running great for 40 years. I have checked all of the wiring between the ECM and the CCCI. All good. Also checked wiring...

    Engine Cranks no Start

    I apologize for not being clear on this. I replaced the module under the coil pack along with the coil pack. It's difficult to figure out why it would be fine one day, parked it in the garage, and a few days later it won't start.

    Engine Cranks no Start

    I just got an OTC 4000e Scanner with the appropriate module. I am not familiar with it but it came with all of the documentation. Does anyone know if you can perform tests on specific circuits to find out if there is a break or a problem in the wiring, or if you can run tests on specific...

    Engine Cranks no Start

    I just pulled all of the plugs. They are wet from gas. I take that as meaning that it's not an injector/fuel issue?

    Engine Cranks no Start

    I replaced the coil pack and still nothing. I put a spark tester on the plugs and there's no spark. What would cause that with a new ignition control module and coil pack?

    Same behavior with the MAF unplugged.

    Engine Cranks no Start

    I have a 1927 Ford Model T. My dad and I had it built back in the mid 90's. It has a Turbo 3.8L that was to go in the 1989 Turbo Trans Am. Other than a few niggly issues the car has be very reliable until a week ago. I took it for a drive last week and it popped back through the intake a couple...

    Surge after Cold Start

    I got a compression tester but none of the adaptors fit in the sparkplug hole. There is one that is the correct thread count and size but it won't fit down in the sparkplug hole to reach the threads. Does anyone know what adaptor I need?

    Surge after Cold Start

    I disconnected the vacuum hose that goes to the EGR and EGR controller and it made no difference. Surging cold start - I'm not sure you will be able to really hear this over the electric fan - https://photos.app.goo.gl/1ahM2t4oEfmBqY6N7 Idle after warm-up...

    Surge after Cold Start

    Thank you for the information. I will check the coils. Thank you for the "how-to" on that. I'm "leaning" :Dtowards a vacuum leak for now. Can I disconnect and plug the vacuum hose after the check valve going to the EGR? In essence disabling the EGR valve.

    Surge after Cold Start

    Thank you for the replies. I apologize for not providing enough information. The engine and transmission is what would have gone in the 1989 Pontiac Turbo Trans Am so it is a derivative the GNX engine as I understand it. We have had it since the early 90's when we purchased it new and put it in...
