    • Original Honda part for a great price
This part is 100% Honda and was provided in a sealed package. Going direct to Honda would’ve cost $150. Worked perfectly.

    • Engine hesitation after startup maybe relay problem
Only use OEM Honda nail relay. Very complex relay has to be the best quality.

Replaced RZ-0158 with this one (RZ-0159) and works great. Seems to be a newer version.

    • Helped fix 1998 Honda Accord engine stalling problem
If you have a 1998 - 2002 Honda Accord that has a problem with the engine stalling/dying on you when you are driving, I recommend doing two things: (1) change you main relay (for fuel injectors/fuel pump). That is this part that I am reviewing here. (2) Also, change out the ignition wiring because over time that gets old and wears out. Here is the link for this part: https://www.amazon.com/gp/product/B002E53RN6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Changing out both parts is pretty straight forward and you can do it yourself. See Youtube for some good videos. It took a long time for me to figure out what was causing my car engine to stall (or not start on hot days), but I think I finally resolved the problem by changing both parts out. I have not had an engine stall since replacing both parts. If you think you know which part is failing, you can choose to just change out one part; but if you're not sure which component is failing, I recommend changing both. If you haven't changed out either, it's probably about time to replace both anyway. I hope this helps someone. This is advice I sure would have loved to have read a long time ago. ... show more

    • No more stalling
My 2000 Honda Accord was stalling while driving quite often. Car was sitting in the shop for 2 weeks and no one had a clue what is was. I did some research and saw this relay was a common issue. Came on here and bought one and went up to the shop and replaced the old one. Problem solved! Drove home and haven't had an issue since! ... show more
