2000 Accord 2.3L Just...

2000 Accord 2.3L Just completed an engine swap as well as an automatic to manual swap. I swapped everything from a car that was wrecked but ran great before that. Switched out the computers, wire harnesses, and the entire dash as part of the process. Car will only crank, and the MIL does not ever come on even for a bulb check. Scan tool cant communicate with computer. Ideas on where to start?

Mechanic's Assistant: Have you checked the fuel supply? And are all the spark plugs working?

Yes all good

Mechanic's Assistant: Are you fixing your Accord yourself? What have you tried so far?

Yes. Im a former tech so i know my way around but this has me stumped. Checked fuel, and spark... fuses, all the common stuff.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I dont think so

I just heard from my mechanic. You were right...a $45.00 job. THANK YOU!! Your response was received in less than 10 minutes!!

Linda B.USA

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA

Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help.

Mary C.Freshfield, Liverpool, UK

This expert is wonderful. They truly know what they are talking about, and they actually care about you. They really helped put my nerves at ease. Thank you so much!!!!
