Hello. I have a 2006...
Hello. I have a 2006 mdx 200,000 mi. My wife was diving it and it quit running and wouldnt start back up. Iv checked the fuel and its pummping fine. Timing belt was replaced about 6 months ago. Will crank but will not start. The green key light in dash goes out as it should so i dont think its that. Its showing no codes but we replaced the battery due to her cranking it dead. So that may be the reason for no codes. Any suggestions?

HI,

Ok, try either pouring a little fuel into the throttle body or spray some starting fluid into the throttle body and see if it starts for a few seconds and let me know

And do you have a fuel pressure gage, engine cylinder compression tester, voltmeter and scan tool with live data feed?

I do have a scan tool with live feed but no compession tester or fuel pressure tester. I took the fuel line off and turned the key o and it filled a bottle up pretty fast so i believe i have good pressure. Wont fire with starting fluid. Pulled a sparkplug. No spark

Hi,

On your scan tool are you getting either crank or cam signal, or rpm signal?

Is the engine turning over at normal speed or quicker than normal?

Ask Your Own Acura Question
Customer reply replied 8 months ago
Normal speed. Not sure which readings are the crank or cam signal 0 rpm.

HI,

Zero rpm signal means either timing belt, crankshaft sensor or camshaft sensor.

Because it is turning over at normal speed, I dont believe it will be the timing belt, but may have to check it.

Ok, let me see if I have a test procedure for the crankshaft position sensor.

On live data, crank signal should show as ckp and cam as cmp

Ask Your Own Acura Question
Customer reply replied 8 months ago
No ckp or cmp listed

That is fine. we know that one, the ckp sensor is most likely, since there is no rpm signal. the tachometer gets its signal from the crank sensor

What Customers are Saying:

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

Thank you very much for saving my daughter and her family a lot of money on her Honda. You are definitely on my list for future help. Thanks, again.

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

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
