HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Ok, there are several possible causes including faulty ecu, data line fault, or dlc short or open. I need the vin number to pull the wiring schematics for your vehicle

Hi,

Ok, I pulled up my database for this by the vin number and while I have some information, I dont have ecu pinouts or wiring diagrams, so I will need to opt out and see if another expert has them to be able to help you

used both my computer today on other vehicles worked perfect thanks sandy
Expert:  Greg replied 10 months ago.

Okay when this happens we find that the cran shaft sensor malfunctions ,

Causing the Scan tool to to communicate with the ECM .

Disconnect the battery .

Disconnect the main connection on the injection pump .

Reconnect the battery

Check for communication with scan tool .

If you now have comms replace the speed sensor on the injection pump .

Do this then get back to me if needed.

Expert:  Greg replied 10 months ago.

Okay ,

Does the scan tool turn on but it says no communication ??

or does not turn on at all.

Greg

Customer: replied 10 months ago.
hi it turns on and try's to connect but say connecting error of something along that line
Expert:  Greg replied 10 months ago.

Okay if the ECM worked on another car then you will have a comms problem though the wiring harness .

you will have to check the wiring from the DLC to the ECM.
