Expert:  justinsbg replied 1 year ago.

When you turn the ignition switch to the ON position (key on-engine off) does the check engine light come on for a few seconds and go back out? Does it come on at all?

Customer: replied 1 year ago.
do you have engine management wiring diagram and rerays location
Expert:  justinsbg replied 1 year ago.

You seem like you might be slightly knowledgeable with electrical testing so I will provide the diagram and relay locations. There are two main relays behind the glove box. If you have any questions about what voltages there should be at certain points just let me know and I will assist with any questions you have regarding the diagrams. I would appreciate a positive rating from you though so I get credit for my time. I have not been paid at this point and won't be until I receive a positive rating from you. I will continue helping after you rate so don't worry about that.

Expert:  justinsbg replied 1 year ago.

Please check the two fuses related to this circuit. Fuse 6 under hood and fuse 17 under dash.

Customer: replied 1 year ago.
fueses are ok
Expert:  justinsbg replied 1 year ago.

Try providing a ground for the Red/Yellow wire coming off of the PGM-FI relay and see if the engine will start. You can use the pin out diagrams that I provided to help you locate the correct wire at the ECM. That last wiring diagram I provided you can see which wire I'm referring to. I basically want to see if the ECM has lost it's ability to ground that relay, or if there is another reason it's not grounding.

Customer: replied 1 year ago.
already check for those
Expert:  justinsbg replied 1 year ago.

You already provided a ground for that relay? This isn't the fuel pump relay, this is the other relay called PGM-FI relay 1.

Customer: replied 1 year ago.
already check PGM-fl relay1 nex to the fuel pump relay under the glove box
Expert:  justinsbg replied 1 year ago.

I didn't ask you to check the relay, I want you to ground the wire I specified. That is not "checking" the relay. I'm concerned about other issues related to the relay, but not the relay itself.
